iapa Posted January 27, 2017 Share Posted January 27, 2017 Not sure this is in 'Beginners' other than we are all beginners in thi shabby, there ar eno 'professional' amateur imagers I have couple of issues with my guiding, log file attached, where the DEC goes running way off after a while. I'd watched it for about 30mins and all was OK. Last night I manage to get some 240s exposures of M51, Backyard EOS was used, ISO 1600 to try to get rough some of the haze. Of the some 23 where usable. Ive attached an example of an unprocessed unusable image.. The result is below, not compensation applied as yet. Debayers/demosaiced, intensity normalised, aligned and cropped (to remove uneven edges from stacking and drift of image) using Nebulosity 4. As was background colour offset, auto colour balance and some stretching. A bit of leaves in Photoshop SCC2015. The OTA was balanced in DEC after cameras etc. added. Balance is RA was with OTA east, with a over balance to that it would tend to drop downwards if released from about 45deg about horizontal - 'East heavy' M51 did not go past the meridian until c 04:50 this am at which time capture was halted. Average outside temp c -5C. PHD2_DebugLog_2017-01-26_212935.txt Link to comment Share on other sites More sharing options...
