EDIT: I think this is the first time I've seen someone post details of their calibration frames. Something I just take for granted... considering its the light frames that count. LOL.
Anyway, you may wish to check this flats analysis on the ADU, quantity to make a master - http://www.darkhorseobservatory.org/dark_horse_observatory_22oct07_021. htm
Point being, don't waste too much time going for "bucket loads" of calibration subs when the value returned is minimal. |
The reason i didnt raise the black point was just personal, i thought it looked more natural that way..... each to their own i guess.(
have played with it since your post and did an auto levels in photoshop......
next time)
I put in the calibration subs as i have had a discussion with a number through PM about how many to use, figured more is better, put the info in more for those whom i have had discussions with, and it got a nice link from you which i will peruse after this post.
i am willing to try /experiment to see if i can improve my images rather than just settle for OK. Some times it helps ....... and sometimes it doesnt, its all worth a try.
As always thanks for your input jase.
Leon, Gama, Hagar, Ric, GaryH, RB, Thanks for your kind comments.
