groberts Posted March 21, 2017 Share Posted March 21, 2017 Having purchased the 1600 MM-cool at the end of last year, what with one thing and another (Xmas, travel, EFW problems but mostly cloud – lots of it!) I’ve really only just started to try to using it. This camera marks my attempt to transition from DSLR and boy is it a whole new ballgame. With a brief gap in the cloud last night, using APT I focused on Sirius and then turned to M44 for a few 30 sec luminance frames before the cloud inevitably returned. I just wanted to: (a) obtain focus with the new set-up – I’m also new to APT and used the Bahtinov aid (b) run cooling and (c) obtain some basic luminance subs just to see the outcome! - As far as focus is concerned visually the Bahtinov spikes looked good + using the APT aid the focus circle was OK but still not sure if I have nailed it (Image-2 below), how can I improve this? - Using the APT Cooling Aid the temperature did not seem to change – having set the parameters I then started. Am I missing something or do I have a problem? - On using DSS the resulting stack (Image-1) is covered in weird artifacts – what on earth is happening here? - Looking at the aforesaid stack in Photoshop the image looks OK but when ‘fitted to the screen’ is covered in a Bayer-type grid (Image-3) – any thoughts?
