Mar 12, 2014 02:06 | #6 stars seem pretty round for 400mm, nice job on the tracker. Try exposing for the Surrounding nebula, and then the core. Looks like you've got the core data down pretty good now. A good free application is whitecalc and hasta la vista green, they help white balance astrophotography images very well. Your images would definitely benefit from proper white balance. Also, I bet you could get away with shooting iso 6400 on that full frame body, especially if you are shooting dark frames and bias frames. Nice job and keep em comin. Clear Skies! Wes

They are both design by the same guy. Here is a link to whitecal http://www.deepskycolors.com …hop-Plug-in-Whitecal.html Wes

Just a question, would I be able to re-use the images I already have of the core. If I go out and get some longer exposures using the same settings would I be able to stack them with the images I have already taken.
