  1. Hi everyone, My viewing has finally got quite bad so it's definitely time collimate. I've been putting it off for ages, and have read some guides, but am just a bit concerned about totally wrecking it without someone to help me! Plus theres the fact it'll be pitch black when I attempt it.. I don't have a collimation tool at the moment but use a bottle cap with a tiny hole made in the centre, I think it works okay...Should that do? Also, where should I start? I have never moved the primary mirror but I have adjusted the secondary, which do you think I should start with? I realise it's quite a simple process but am still a bit worried about it! Thanks
  2. Thanks for all the mentions - Should've said, I'm using a Skywatcher 8" dobsonian (200p)
  3. Hey all, Clear (albeit literally freezing) night due this evening. I'm in the UK and was wondering if you have any recommendations for things to look for. Due to the position of the house I am restricted to facing north with a 90o field of view either side, so I guess I can see directly East and West, but nothing beyond that! I saw Andromeda last night (as a smudge of light!) but I'm not too sure what else to look for! If you guys could give me a couple of things in that direction to look out for, it'd be greatly appreciated! Thanks (I have stellarium btw, so I can find things that way if you can give me a few names!) Con
  4. Hey all, Have a late start tomorrow so have decided to stay up! The sky is clear, but annoyingly the moon is out, full, and almost directly overhead...Coupled with the city lights (though it's not that bright), it's not ideal for viewing...Could anybody recommend a few things for me to take a look at in these types of skies (not the moon!), or is it one of those nights I should write off? Thanks! con
  5. I'm a real newbie to this stuff but I recently bought a skywatcher explorer 200p on a dobsonian mount and it's brilliant. Not hugely transportable (though It might fit in a large car..) but it's given me great views and was very easy to collimate. Also, for me at least, learning the sky and finding things for the first time has been great fun, so in my opinion I'd recommend against a GoTo scope for the time being!
  6. It's a dobsonian Skywatcher 200p 8" (love it ). Have followed your advice and remounted it facing down. Thanks
  7. Good point on the weather! Am I right in thinking Mars won't be visible for almost a whole year?! That's what I thought after watching stellarium! Also, just brought my scope in and its very dewy, it's in a warm room though..Can i just leave it to de-dew itself, or should I set the hairdryer on it?
  8. Just realised I've not left nearly enough info for! I'm in a small city (not a lot of light pollution) with an 8" dobsonian!
  9. Hi guys, It's been almost a week with the scope and I've still not seen Saturn. In the UK where I live it is only up in the early morning (about 5am and on!). As it's the weekend, I have decided that I will attmpt t ostay up to see it! At about 5:30am it will be at about 20o above the horizon according to Stellarium.. sunrise isn't til 7:40 (apparently) and if I can make it til 6 it'll be even higher! Is 25 or so degrees too low to get an alright view? Should I just wait for another time when it's got better visibility? Hope you can advise! con
  10. Hey all! I got my first scope last week (skywatcher dobsonian 200p) and was going through the receipt etc earlier (from FLO) and realised I've got no idea about a warranty. I am sure nothing will go wrong, but like to know what my options are should anything break! Does anybody know the warranty on these scopes? Can't find anything on the receipt! Thanks all
  11. Got it, hairdryer it is! A friend managed to get a finger print on the secondary which I used a very soft tissue to clean - Will this have done any damage to the mirror? There is nothing that I can see but am worried I have somehow impacted my view quality! I am probably over worrying! Cheers Con
  12. Hey all, First off, thanks for all the help so far! My 8" Dob is set up nicely with your help and I think it's (adequetely) collimated. I presume this because Stars seemed pretty sharp and when I unfocused them they seemed to be very close to a perfect circle! Last night I spent about 90 minutes looking at Jupiter, probably very boring to most of you guys but I was very very impressed! At times it would become more clear and I could see a LOT of detail, and the moons etc. Beautiful! The moon was also very impressive, I felt like I could see into the craters! Annyway, after a few hours the scope started to get covered in dew. I (stupidly) used a soft tissue to clean the secondary mirror, however after some reading into mirror maintenance realised this was a very stupid idea..Luckily I didn't scratch it! Anyway, what do you all do when the scope starts to dew up? Is it time to just give up? Finally, when I take it in it's often very wet from the cold/damp air..I understand that the scope is made of pretty simple materials (metal and glass by the looks of it), presumably it doesn't need to be thoroughly dried, but I wanted to check as I'd like it to last a long while! Thanks all
  13. Definitely made a huge error, I meant 22CM! Oops...I wanted to get it out tonight to mess about with the colimation, I think now the secondary seems adjusted the primary will be pretty simple..Damn fog.. Con
  14. Thanks for the reply. I've watched several videos and read a few guides now..I find it odd that the primary mirror needs adjusting, especially as it seems to lay quite flat! I will take it out in a bit and see if it appears alright, what I am seeing now seems to coincide with the guides, so I think I'll just have to wait and see. Con
