Guest Steve Posted September 29, 2012 Share Posted September 29, 2012 It's a lot to get to grips with - scope, mount, laptop, focusing. subs, stacking, post processing - still a lot to learn. But here are my first efforts from KH2012: Pleiades, Andromeda, M13 and M31 - can you tell which is which? The galaxies were through the Celestron C9.25 on an ungiuded CGEM with a Canon 450d computer controlled with BackyardEOS. The Pleiades was taken with the Williams 66mm Petzval. Processed in Deep Sky Stacker and some tweaking in GIMP. Lessons learned: Focussing is a pain but do-able by taking previews and checking the image on the laptop - trial and error. Maybe a Bahtinov mask would make life easier. 60 seconds is about as long as I can expose for before I start to see trails - I had some 120s and 180s subs that were unusable. Be methodical with naming of subs for later identification. I need to get a set of Darks prepared for exposure lengths and probably ISO setting. I used some darks but no flats. DSS and GIMP are usable but I've no real idea what I am doing - just playing with the controls at this stage! Next steps will be more of the same to find my feet and then maybe think about auto-guiding.... Steve Link to comment Share on other sites More sharing options...

Antares_Paul Posted October 1, 2012 Share Posted October 1, 2012 Steve - a Bahtinov mask will be the best sixteen quid you have EVER spent. http://www.morris-engraving.co.uk/bahtinov.htm Regards. Link to comment Share on other sites More sharing options...
