That is awesome tracking for 400mm! What does you tracker look like and how do you polar align?

Thanks corduroy.
see my thread here regarding the tracker:
https://photography-on-the.net …/showthread.php​?t=1359426

For polar alignment I installed a red dot finder on the tracker which I lined up with the hinges.

Reprocessed using PixinSight trial version. Managed to bring out some minor detail in the Running Man nebula…

Hi Ken, WOW

That is a fantastic result, well done.

The hard work has really paid off there.

That first shot needs to be framed.

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!

Thanks for the comments calypsob. Having a look at HLVG now but can't find the whitecalc app, any ideas.

white cal is on the same site as hasta la vista green, you use it after running white calc. They are both design by the same guy. Here is a link to whitecal http://www.deepskycolo​rs.com …hop-Plug-in-Whitecal.html (external link)

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.
