  1. this was going to be my subject last night, got everything setup, spent an hour guiding to ensure the new cam is working as it should, went indoors to warm up a little and let the scope cool down. Went back outside 30 mins later and could not see a thing (blumming clouds). I'll be leaving Northern Ireland and the Mourne Mountains soon and heading for the mainland, the Mourns seem to be a cloud magnet every time i want to image. Nice pic by the way.
  2. being as m42 will be leaving us shortly what is the next easiest neb to image? nothing too hard guys as i have only just started imaging so something easy to find ?
  3. your pic look similar to mine, the north/ south line of the crosshair(blurred one) is slightly offset to the left compaired to the vivid thin black line within the center spot, so it looks as if the thin line is spot on but the blurred line is off if you get me???
  4. The scope is an LXD75 N-6AT (f/5) used more for photography than visual. aint ideal i know but i just want to get the best out of it.
  5. when you say it's off slightly, can you explain where mate? i'm new to this
  6. Thats one question i meant to ask, when star testing do i just slightly de-focus or rack quite a way out. The reason for asking is i carried out a star tested last night and defocued from what looked like a pipoint (in focus) star to say a 2cm size star and got the pinched mirror pic on astro baby's website, but if i very slightly defocus i can see the rings around the star showing perfect collimation. i removed the primary thinking i had tightened the clips down to far but the are loose, when i say loose i can easily place a playing card between the mirror and clip. The clips are made of a very soft rubber so have a little give in them
  7. went and bought a cheshire collimator as pictured below as i did not trust my lasor collimator and was stupid enough to buy it in the first place, cleaned both primary and secondary mirrors using this tutorial then collimated them with astrobaby's tutorial. http://www.astro-baby.com/collimation/astro%20babys%20collimation%20guide.htmhows it look with your trained eye??????
  8. a unmodded spc 900 is great for planetary work but no good for dsi, as you wont be able to gather enough light to process the faint nebula or deep sky object. this will hopefully explain it in more detail Exposures for Deep-Sky Astrophotography
  9. 100% improvement mate, well done and another nice m42
  10. cant wait to test my guide system out when i see pics like this. Blinkin clouds
  11. spc 900 probably wont give you any better results mate. use your nikon and use longer exposures and iso settings to experiment before tracking becomes an issue. Start with an exposure time of 30 seconds and an iso of 800 and adjust from there. The spc 900 cam is great if you have it modded for long exposures and want to guid with but you would be better off modding your dslr or buying a better dslr that has been modded. For instance an unmodded canon eos 350d body will cost you around £120 and will be far superior to a spc900. You would need the T-piece and adaptor about another £25. if you really want an spc900 modded webcam there is one here on the local auction site. http://www.ebay.co.uk/itm/phillips-spc900nc-flash-upgraded-web-cam-long-exposure-mod-/160754099276?pt=UK_Photography_Telescopes&hash=item256db0e44c just my 2 pence worth
  12. I watched this youtube vid (there are nine parts to watch) to give me the knowhow along with my previous post (astro babys) hope this helps you mate.
  13. This is the method i use. Astro Babys Guide to Collimation
  14. it's great to see different variations of the same neb. i can't see anyone getting bored with it at all esp me.
  15. getting rid of the grainy red in the sky will make that captured image pop. if you have photoshop there are plenty of tutorials on youtube how to adjust this. another nice capture
  16. The "Great Nebula" in Orion is likely the most photographed deep space object there is. It is considered one of the most beautiful objects in the sky and a smidgen away is the horse head. lovely pic
  17. dont forget you darksthought mate. nice capture by the way
  18. fantastic pic and very pleasing colour. was this pic taken with your canon 350d (self modded) or your canon 5d? Also how hard did you find self modding your 350d, i'm itching to do mine but just have not got the dogs danglers to do it yet!
  19. It aint as bad as it sounds, the plumbers ptfe tape sorted out the little bit of slop in the focuser and using various sites, youtube, astrobaby i have managed to sort it out.
  20. going to start from scratch with both the secondary and primary mirrors by removing them and giving them a clean as i have had this scope for over a year and even then it was bought second hand so there is a fair ammount of crud on both mirrors, got nothing to loose really as my new scope (Altair Astro 115mm f805 EDT APO) will be with me soon. cheers for your help Jason D
  21. i think what i need is an 1.25" SCA Adapter but can only find a SCA T-Adapter or First Light Optics - HoTech SCA laser collimator i now believe this to be one of my problems as the collimators i have move when i tighten up the focuser thumb screws.
  22. Many thanks Jason for your input. I have just read the last post you placed in this thread - http://stargazerslounge.com/discussions-scopes-whole-setups/177056-laser-collimation-not-all-its-cracked-up.html I think my problem is with the secondary mirror not being correctly positioned under the focuser, it is round but i think it is very slighlty twisted as i cant see all three clips on the primary. i also have another problem - when i insert either the lasor or cheshire they both have a very slight wobble so dont fit perfect. When i tighten the thumb screws that hold them in place this tilts them slightly. I am going to wrap some plumbers ptfe tape around them to get a more snug fit and see if that makes a difference or is there some gadget that will fit in a 1.25" focuser to center them?
  23. i'll take some pics tomorrow morning to try and explain in more detail
  24. collimated my laser collimator and still have problems - see my post http://stargazerslounge.com/beginners-help-advice/177491-collimating-newtonian-help.html
