A flat should show if its the sensor I expect.
I think it could be dust and dew...photoshop them out
The work load sure gets high as you do more in this game..with the narrow band you have 7 different filters..so every thing is times seven..I don't know what needs what so its seven until I learn more.
.I am not sure if you take darks and flats for all of then...probably to get into everything in the future will I get darks and flats for each.
.and in the case of Orion I guess a variety of exposures.
.mmm 15 seconds at small gain times seven then darks and flats then I guess some 30 seconds with darks and flats and some at 2 minutes with darks and flats phew... I knew there was a reason I wanted not to go narrow...some much to do....and I still have to work Rays chart into things to work out exposure and gain
...
Damn it I should have just bought a Hubble coffee table book full of photos
.
All I do is astronomy. . buying stuff, setting up new stuff, learning about new stuff, fixing stuff, adjusting stuff and then stacking on pappy (the desk top) and processing on lappy...I need a fridge stove and toilet in the room to save time
Damn... its clear outside now and I feel compelled not to waste it but I need sleep.
When I miss a night it goes crook the following night...I want to set up the new camera on the eight inch ...maybe get both mounts going with a camera on each
