A lot happier with this process

r rgb C11 sigma extender 30 secs each colour

run through pipp stacked in AS2 wavelets in Astral image combined and finally beaten into submission in PS6

Nice one Steve.  Great to see the moon and shadow.

A little red maybe but some detail showing through. I think you would benefit from longer AVIs and hence more frames captured. 150 secs each colour really wouldn't be a problem at that image scale.

and I knocked the green down a tad :smile:

150s / channel I thought was too long but will give it a go next night we have with decent clear spells

maybe too far the other way now

maybe too far the other way now

Looks a lot better, It was too red

But Freddie is right about the times capturing. Look for a tutorial about winjupos and under good seeing up the image scale with a higher power barlow, 6000mm is a good scale though that's with my camera, yours might do better a bit lower. a C11 can do wonderful images even in the UK

My x2.5 powermate is out on loan so I'm using a sigma teleconvertor  @x1.4 maybe the x2 would be better idea if the local seeing would hold, the obs is a bit cramped so i have decided the 11 can go back on the EQ6 outside as it will also give me room to move.

I have convinced myself that some of the seeing problems are down to me being in the obs with the scope

the x5 PM is too much except on maybe 1 night every 5 years

I will have another go at winjupos

I did try it a couple of years ago but failed

thanks for the suggestions and input
