This was an exercise again with short exposures not because auto guide was playing up but the seeing was very jumpy and little clouds kept rolling in and out of the field of view...I had to disgard a great deal but expect there is about 3.5 hours of data all up...no darks or special treatment as I don't feel like really trying whist I have oval stars ..see below.
I am having trouble with oval stars on the outer limits which I corrected to a large degree but the problem still has not gone away..I had altered the filter wheel and moved things and cant find the sweet spot I once had although I am starting to think the sensor may not now be laying perfect..I have a tilt corrector on the 8 inch that I may put on the 80mm...anyways there is still so much stuff I need to do, so I thought lets see how high I can run the gain and so most of this was captured at 30 seconds with gain from 350 to 400... surprisingly the data ws not too bad surprising really..Used all filters except O11 and S11 which I took but screwed both sets up a little so did not include them in this work up,..now I know its too saturated for most but I like this approach as I see more detail...I did have my eyes checked but the specialist said I can leave doing my cataracts for 18 months
Anyways been on this for two days and probably lost all sense of what is right...
