Nik Szymanek has been writing about it the last few (4 I think) issues of Astronomy Now. Neil

HI again Karen, I live just outside Marchwood. And the apps are good but a while ago I put together a little presentation to help beginners navigate their way around the night sky - I've attached it here - it may be of some use. Now all we need are some clear skies. Regards Neil NightSkyBeginners.pdf

Thunder & lightning here in my bit of the New Forest

I'm lucky in that I have a dome, so I just leave the kit capturing darks at the end of an observing session (or sometimes do it the following morning when ambient temp is low) Neil

That fluctuation may have been caused by the cam having to work flat out to maintain the temp - what ambient were you working at, bearing in mind at best it can get to 35-40 below ambient? Regards Neil

Sharpcap default to SER video files when using very short exposures. It goes back to Fits or tif or png when exposures are greater than 1sec. Also, you can change the file type in Sharpcap itself (turn off the auto button) or you can set the default file type in the sharpcap settings. Neil

12 luminance subs 11 bad pixels 10 (k)nights with clouds 9 RGB frames 8 amps of power 7 planets shining 6 wavelets altered a 5 position filter wheel 4 narrowband filters 3 element Triplet 2 stars binary 1 Crab Nebula glowing in the sky Actually just a ZWO ASI 533 - there has been so much bad weather I didn't think I'd make it any worse

to me, it looks like Registax is not Debayering the image - set debayering to RGGB before stacking - or you're not capturing in the correct video format - either RAW or RGB24 - preferably RAW
