At least with nights of average seeing one can get reasonable data for DSO imaging. Maybe not luminence but certainly the RGB.
Great seeing
Average seeing.
Long and the short of it though and for those wanting to learn about seeing, Mikes point is well made. Luminence should only be gathered near the meridian and during good seeing. Likewise planetary imaging should not be conducted in poor seeing. If you are using one shot colour, well image when the seeing is best if you can, but if you have constant cloud, image whether the seeing is good or bad. |
Thanks Mike and Paul for posting these, it makes us beginners feel a lot better knowing it isn't *always* our fault
I find for planetary bad seeing is amazingly awful, it makes it impossible to focus as the planet dances around like a cork in a washing machine. What do you do when it is like that, or do you just pack up and try again on a better night?
