    If you are in an area with little or no light pollution, every beginners telescope from a reputable astronomical manufacturer should give excellent views.

    Reputable companies in this category: Skywatcher, Orion, Meade. 

    What you have to decide is what type of telescope and mount you want.

     

    Telescopes:

    Nb, just the telescope tube is known as an 'Optical Tube Assembly' or OTA.

     

    -Newtonian Reflectors ('Newts') They use 2 mirrors in a tube. The tube is open at one end with the larger (primary) mirror at the closed end of the tube. You get the most aperture for you money because mirrors cost less than lenses to manufacture. These reflectors can be mounted on an astronomical mount and tripod or, more commonly now,  on a dobson mount.

    Biggest disadvantage of a Newtonian Reflector: collimation (adjusting the position of the small and big mirror so the sharpest in-focus image is achieved).

    Also because the tube is open, the mirrors will need to be cleaned (following instructions on the web) relatively regularly. Finally, they can be unwieldy on traditional mounts and tripods . For this reason, Dobsonian mounts were invented. A dobsonian mount is a type of mount that  sits on the ground: the Newtonian tube is supported in a rotatable box. No tripod and counterweights are needed. Very large Newtonians can be mounted this way.

     

    -Refractors. These are what most people imagine a telescope to be - a long tube with glass lenses. The longer tubes are typically used for Moon and planets at high magnifications. Shorter tubes emerged in the 1980s around the time of Halley's Comet. These are used for lower magnifications and for 'sweeping' the Milky Way and wider Deep Sky Objects.

    Advantages -

    They tend to have very 'clean', aesthetically pleasing images.

    No collimation is needed. Closed system so inside lens surface stays clean.

    Disadvantages: Smaller aperture for your money compared to Newtonians. Longer tubes are unwieldy on cheap mounts/tripods. Refractors can get very expensive (i.e. ED refractors and APO refractors.) 

     

    - Schmidt Cassegrain and Maksutov Cassegrain Telescopes - These are compound telescopes that use a combination of a glass front and a mirror to fold the incoming light.

    Adv: High magnification in a shorter tube than a refractor. Cheaper and lighter than a comparable refractor.

    Closed system so rarely need internal cleaning.

    Disadv: Narrow field of view. Collimation needed but easier than a Newtonian reflector because you only move one mirror (Some 'Maks have two moveable mirrors but they are not so common.)

     

    Mounts.

    Altitude-Azimuth (Alt-Az) Mount:

    This is the easiest mount for a beginner to operate: up down and left right. 

    They tend to included with beginner OTAs.

     

    A dobsonian mount is an Alt-az mount. You can also get table top Alt-Az mounts.

     

    Equatorial Mount:

    This mount has to be set up so the mount points at the Celestial North or South Pole. It allows for long exposure photography.  You need counter weights. 

     

    Hope this helps

    Bumping this thread because I have a result!

    First of all, I decided to let it go to court.
    The first court date I got was in April, and it was postponed twice due to Covid. So the date was this morning, 10.30.
    I'd decided to hire a lawyer. I know a lovely lawyer just five minutes walk from my home, whom I'd met earlier this year in another matter. I went to him just after lockdown opened so I was one of his first clients after lockdown and it was all a bit disorganised -- he really is lovely, which is not a work I've ever used on a German lawyer!!! 

    ...
    I went outside and Barry came out and said I was being sent to prison for 14 years but he'd visit me there.

    And then he laughed and said the case was dismissed and I should drop the €50 into his office. 

     

     

    Sometimes I really miss Ireland

    I'm pretty sure that this courtesy was thought of a long time ago where we lived in small communities and talking ill of the dead was seen as likely to upset loved ones.  In this day and age it's just not the case anymore, when famous people die we don't know their loved ones and they are very unlikely to see or hear anything we say.

    I suppose it's a universal truism - the dead cannot defend themselves irrespective of their social standing. 

     

    I think maybe for the ancient Greeks and Romans, it was up to the Gods to judge people, not mere mortals.

  4. I was watching a tv program a while back and it was about a couple and their young child who lived on a house boat near Hamburg - he worked as the harbour master. It all seemed very nice. If I remember correctly, they had bought the whole harbour.

    @Brexitania 

     

    Another conundrum for @Brexitania to consider, with a no deal scenarion looking more likely there's a good chance that UK citizens will need to resit the driving test here in Germany in order to exchange their UK licence for a German one. This is the norm for Third Country Nationals where there's no reciprocal agreements. 

     

    Ouch! 

     

     

     

    I know it's all speculation but the latest mood music from the current round of negotiations is more positive that there will be a deal (albeit more limited in nature than what London wants). The Pound is recovering against the Euro also which indicates the markets think a deal is in the offing. 

     

    Of course it could all go pear shaped.

    Looking back I had EXCELLENT swimming teachers who taught the moves very precisely. Learnt to swim aged 7. Somehow their details have always stayed with me. Which is why I thought I could pass it on... Must have been an impressionable age. And the Brits had all those Victorian swimming pools and a lot of fishermen... 

     

    I read somewhere that traditionally, fishermen didn't learn how to swim because it was considered unlucky (this could just have been in Ireland, not sure).

  7. OP, it really sounds like a horrible situation - you have my sympathies.

     

    Just trying to think who might have made the complaint. Do you live in an apartment or house with retired neighbours? Maybe someone that has made complaints about children's noise in the past?  Or didn't but lives close by? 

     

    It could be the case that they thought your child would start Kita in September but clearly now it's October and you haven't started Kita. This would indicate to me that it's a neighbour that made the complaint, for whatever reason. If it had been a family member, they would have made the complaint earlier.

     

    I don't know where you live. If it is the former West, the reportee could be someone from the former DDR - sending children to Kindergarten early was something seen as normal whereas 3 or 4 was the norm in the West (according to my wife).

    You have been away from Germany AND out of school such a long time that you are completely out of touch with German reality (although reading the media would have helped):
    - No, kindergarden teachers aren't supposed to willy nilly hug the kids anymore (based on previous abuse cases)

    - No, teachers no longer are considered professional when wearing speedos. It's swim trunks now.

    - Students assisting other students in sports (so-called Hilfestellung) has been the norm for decades

    - And reading is fundamental - the OP just described that of course the teacher intervenes in emergencies (quote you: "a kid falls off the parallel bars and gets hurt ") and administers first aid!

     

    Edit: I'm kind of sad to hear the old German saw "You're overreacting! Suck it up!"

     

    Metall, thanks for your informative post.

     

    I'm still curious what do PE teachers do in Turnen? Surely there has to be instances were some sort of physical contact is unavoidable? 

    0

  9. OP,  what happens when the children have to do Turnen? It would seem to me that it would be required for some physical contact between the PE teacher and a participating student (obviously in appropriate areas)  when dismounting from an apparatus or doing exercises. 

     

    Reading your posting, it seems that it was a mistake by the teacher if there was a school policy in place regarding swimming. The teacher put the decision on your son which was wrong in the circumstances. 

     

    But in my eyes, it has all escalated way too much. I would personally talk again with the principal and the teacher, clear the air, shake hands and move on. Following this,  it will be crystal clear what the school policy is to everyone present.

  10. We are in the process of decluttering the Kellar in order to build a home office. Quite a bit of success with eBay Kleinanzeige and zu verschenken - we put  up unused boxes of tiles and they were gone within minutes. A guy thought we had more and wanted to drive from Bremen to collect them! Also garden tools and metal. We had quite a lot of childrens things that we made into a job lot - the lady who came brought a big bag of apples that she had picked from her garden which was nice.  A carpet took a while to shift though.

     

    Furniture is almost impossible to give away. It works both ways though - the home office desk and lamp came from eBay also so we helped someone else's decluttering :rolleyes:

    That's odd. The Miele of my parents lasted 25 years with only one small repair. It actually stood in a shed as well. They paid a 1 month salary for it back then in the 1970s. 5 persons household.

     

    I have a Neff myself. This is a subbrand of Siemens/Bosch. 17 years old. I use it 2-3 times per month.

     

    Yes, the old Mieles are legendary for their longevity..you just don't get that level of reliability any more in consumer products.

  12. Ok. Update on the Miele we bought 2 and a half years ago. Couple of days ago, I heard a knocking sound every time the drum was rotated. The Miele technician looked at it yesterday. He said the bearings were completely worn down and basically nothing could be done to repair it. He was really surprised and said usually he sees it in much older machines. We use it a lot but it should have lasted longer in my opinion. This along with the earlier touchpad problem means no more Miele.

     

    Just as well my wife had taken out extra insurance in Saturn or we'd be up the creek.

    Get a new instructor for a few lessons and then reschedule the test.

     

    I had something similar happen to me before I took my motor boat test.

     

    Goid luck!

     

    I second that suggestion! My original driving instructor got stressed with me and I got stressed with him. It got to the stage that I was not making any improvement and hating the lessons. 

     

    It helped that I moved to neighbouring town but I took a break of a couple of weeks, started in a new school (with a younger, but excellent instructor). I had maybe 6 sessions around the new area I would be tested on, had the test and passed first time. The important thing is keep at it but really focus on  your mistakes..As my second instructor said, 'We are in Germany. We never give up!'

    A friend of mine was head of IT at a UK staffing company. He interviewed a Brazilian guy straight off the plane. According to my mate, the interviewee asked when he would find out the result of the interview, and was told it would be next week. The following Monday, my friend was away from the office, and the interviewee turned up. He was under the impression that he had got the job, so he sat down with the rest of the IT guys, and one of them gave him something to do. When my mate turned up the following day, he was too polite/embarrassed to tell the guy he didn’t get the job. 15 years later, I can see from Linkedin that the IT interviewee is no longer in IT: he’s now the Director of that company’s South American operations.

     

    I guess a stroke of luck like that only happens when the interviewer is a British public school type with an inbuilt aversion to “making a scene”.

     

    What's your friend doing now? Actually probably best we don't know :lol:

  15.  Ok, sorry for reviving a 15 year old thread but currently watching Die Bergretter and they've said 'scheisse' 17 (!) times at this stage..and I didn't even start watching it from the start..Oh, make that 18!!

    I used to warch this when I was a boy in London. Because I was feeling a little homesick, I started to watch it again last week and was more than a little surprised

    that most of the characters are now either Indian or black.

    I am not a racist, but does this really reflect the makeup of society today in London?

     

    This BBC article is from 2013 and gives a good overview of trends in UK internal migration:

  17. The music magazine Q has stopped publishing. When the news was announced a few weeks ago, there was an online comment about one of the regular pieces called 'Who The Hell Do They Think They Are?' where they would interview celebrities. Well Jimmy Saville was interviewed in around 1990 and the interview is mind boggling (there's a scan online ) - it's basically the Louis Theroux interview done 10 years earlier.

    There is a general hatred towards foreigners who live here for many years and can't speak the language properly. They didn't get on with me from day one. It happened instantaneously from day one. That means that they heard my German+accent and stereotyped me into a category. There were some colleagues who told me that some managers keep talking about how bad my German is behind my back. This way they raised negativity around my name. After that, even a slight and small mistake, would make it look huge and lead to more negativity. As you would expect, I tried to be very efficient and a good worker to counteract the negative press. Many do that, I noticed it. It's a survival mechanism.

     

    Unfortunately the people at the airport are uneducated people who dropped out of primary school. These are the usual suspects who hate foreigners.

    These are also my managers, even at the higher levels of management. They take these positions through connections and definitively not through skills or educational background. Many express openly their racism and some their love for Hitler. There are times that they don't greet foreigners properly with a handshake (pre-Corona). Some of them greet like Hitler and despite the fact that it got reported it has never been punished.

    Men of power like Policemen at the airport are highly racist against foreigners who work there. Countless examples. They have been warned to not interact with foreigners at work to avoid conflict and scandal. Now they appear and walk like cold and emotionless robots between us.

    Discrimination at work at the Airport of Tegel and Schönefeld is huge. Foreign workers who are born in Germany told me that they got used to it. For me this is new and as someone with an academic background, I am curious to know what I missed all these years that I wasn't in Germany and why the society evolved this way. I find it interesting. I lived in other multicultural societies and I am able to compare.

    But I am telling you. If you want to live racism like in the old days of Germany, get a job at the airport.

     

     

     

    Sorry OP to hear about your experiences. What I will say is you can experience prejudice when you speak the same language perfectly - personally, I had the 'you Irish go home' twice in my life (in the UK and US, not at work). If the person has a predisposition , there's little you can do about it. Move on. 

     

    Racism is out of order at work - you need to report it to a different person and get it investigated properly.

     

    Airports - I suppose you have the normal hierarchies as well as the pressures of working in an environment where security has to be to the fore. It's never going to be your typical workplace.
