Imaged on Sunday night 06-03-22 this is a Barred spiral galaxy with a massive black hole at its core. Luminance of 10 x 300 RGB of 5 x 300 each all binned 2 x 2 scope Celestron 11" with a F 6.3 FR camera QHY9m pro

Thanks it is a good target I have imaged most of these vdb targets well worth imaging them.

Imaged over two nights Luminance of 16 x 300 un binned from 20-12-20 RGB imaged on 22-01-22 all binned 2 x 2 Red 10 x 300 Green 7 x 300 Blue 6 x 300 QHY9m Pro camera Scope WO 90

Imaged on 11-01-22 I had lots of problems that night getting everything going but managed to get four and a half hours in the end but no calibration frames. This is a SHO image Ha 20 x 180 + 6 x 300 Olll 20 x 180 + 6 x 300 Sll 20 x 180 + 6 x 300 QHY294m Pro camera TS 65 camera Bob

I imaged this target on Wednesday night having a bit of a experiment with exposures in narrow band in the past with my ccd camera ( QHY9m ) I needed 15 or 20 minute subs so with my new CMOS camera a QHY294m pro I first tried a run of 10 x 180 in each filter then a run of 600 sec subs I think I need at least 10 minute subs anyway I have combined all the data to give a Hubble palette image. Ha 10 x 180 + 8 x 600 Olll 10 x 180 + 8 x 600 Sll 10 x 180 = 8 x 600 QHY294m Pro 1x1 ( 47 mp ) TS 65 scope Bob

This is my first light with my QHY294m pro at 1 x 1 ( 47 mp ) imaged on 30-10-2021 colour processed in PS I am going to try colour masking in pixinsight to see what the difference is if I can. Ha of 20 x 300 astronomik 6 nm filter Olll of 10 x 300 astronomik 6 nm filter Sll of 10 x 300 astronomik 12 nm filter QHY194m pro camera T S 65 scope

Thanks Adam it is a bit short on data I hope to add to it if I can. Bob

This is the first light with my new QHY294m Pro camera still finding my way with setting / software and hardware only flats applied Imaged on 07-09-21 Luminance of 14 x 300 RGB of 6 x 180 each camera 11MP mode Scope TS 65 Bob

Imaged over two nights 07/08-09-21 Luminance of 13 x 300 un binned RGB of 5 x 300 each binned 2 x 2 WO 90 scope QHY9m camera I think this one will benefit from more data Bob

I had first light last night with my new QHY294M camera and collected LRGB data but when I tried to stack align etc in Image Plus which I have used for other older QHY cameras for years it couldn’t manage to go through with the data as these image files are a lot larger I was thinking this could be the problem has anyone any advice ?

I imaged this spiral galaxy over two nights 14/15-04-2021 Luminance of 36 x 300 RGB of 7 x 300 each all binned 2 x 2 scope Celestron 11" with a F 6.3 FR camera QHY9m Bob

Thanks for that Chris I thought I had missed something with the mirror lock I have been imaging with mine for about eleven years now and it is a struggle at times to keep focus but I now watch all the subs coming in and if the stars seem to go out of focus I do a refocus. Where as I have another set up with a 500 mm FL refractor on a equatorial Mount and it just runs all night with no need to refocus. But for all the problems with long focal length imaging I do like to have a go at the tiny targets. Bob

Thanks Chris for your feed back. I have found in the past that the blue is usually the one with a problem with the Celestron it just seems to effect the brighter stars. You said that your mirror was able to be locked I thought only the Meade scopes had this facility I would be interested to know how you did it was it a DIY job ? I have imaged at F 10 for a few years now but it is difficult to get he right conditions in the UK that is why at Focal lengths of 1764 mm and 2800 mm with the 11” I now bin all my subs 2 x 2 which seems okay for me.
