  1. ok cheers. I have woods directly behind me (blocks anything below 30 degrees! (height not temperature)) so dont think its a heat source but will wait for a couple of hours after sunset to see if this settles.
  2. I have a 80mm refractor (skywatcher startravel) and is generally cooled down for about half hour minimum before attempting to view.
  3. Hi, Over the last few weeks we've had a few clear nights (no clouds) in the evening time. I get the scope out and find that the objects i'm looking at are quite fuzzy or flickering. I know this is due to the quality of the air and movement of it but is there a site or a way in which the quality can be predicted, or easier, a site that tells me! Tonight has been predicted to be clear for a couple of days and i wont know how clear everything will be until i look through the scope! Slightly confused!
  4. Cheers for that. I'm forecast clear skies for an hour or 2 so will give these a try. One or two at a time i think until i know where they are without a starmap!
  5. Hi all. I spent a little bit of time looking for Jupiter when the sky was last clear (January??!!). I found it and the moons but was just very bright and could only just make out the colouring as my scope only has a focal length of 400mm. Anyway, my question is 'What deeper sky objects can be easily seen with a magnification of 32-42?' I've calculated that a 25mm eyepiece with 2x barlow will give 32x. 10mm e/p will give 40x. I think i'm going for orion nebula and andromeda. Any other good simple spots that anyone can suggest would be great. Ian
  6. Cheers, i've dowloaded the DSS and am going to have a play with lots of 1 sec images.
  7. Hi all, advice please???!! I've got a dslr, and want to tak esome deep space photos (orion nebula and andromoda galaxy) Apparantly i need to open the shutter for 30 seconds ish. Surely with the spin of the earth, any pic will be streaked across my photo? I dont have a tracker, Am i right with the streaking? or what do i do? Bit confused!!! Please keep it simple, i'm a simple lad!! Ian
  8. Thanks all. Brantuk, The pictures and links you've posted are superb, thank you so much. I'm off to look for some extra bits now!
  9. Themos, I don't have a very powerful telescope, therefore the eye pieces and the magnification they bring will benefit any pictures i take. I don't know what magnification i'd get just using the scope and camera, therfore i'd like to use the lenses also? I don't know if i need the eyepiece in the optical train, just want to know how to set up my camera so that the eye pieces are in use to magnify any image.
  10. Cheers for that, i'm sure it will all make a bit more sense then!
  11. Am i reading correctly that i'll need a t-mount that is long enough to hold a 1.25" (lens size for my scope) lens? The ones on the links Brantuk suggested are a lot longer than the one i bought?
  12. I don't want to use the lens, i want to be able to photograph what i see through my telescope using the magnification lenses. I thought this was the way to do it until i put everything together. Anyone know what i need to do?
  13. My t-mount arrived today. The only way i can get the camera to attach to the scope is to remove the diagonal plus lenses and attach it directly to the main body of the scope. This means i cant use any lenses to magnify any images as they cant attach anywhere? Is this always the case as it doesn't make sense to me that you can take photos but not magnify the image first? I have a pentax K10d and a startravel skywatcher 80mm refractor and have attached a photo for comments. I'm a complete novice so any basic tips would be most welcome as i don't understand all the terms yet!

    Downloaded Stellarium, thanks for the advice to do so. just wish i could paste my own back garden as the background setting to make it even more accurate!

    I've always been a little bit interested in astronomy and the bigger picture (Thanks to 'A brief history of time'!) Found out about Hartley2 passing this month and read up about it, realised i'd probably need a telescope so bought a skywatcher startravel 80mm refractor scope. Thought i saw Jupiter the other night, was disappointed as it was just a large white dot (got a feeling now that it might have been a star??????) Couldn't see Hartley as the range of view from my garden is very hampered by surrounding woodland (probaly the reason why i thought a star was Jupiter too) Looking forward to g
