Another image from today, double stacked image as the single stacked image had some processing artifacts and the double stacked image looked better anyway.

Enjoy

Nice images Stu!
Are you shooting through a diagonal which is flipping your images? It is customary to have north up and east to the left (just makes it easier to correlate your images with info from the GONG & other on-line sources). Presently your images have east to the right .

Hi P&C,

Yes, I am shooting through a diagonal, need it to get the backfocus. Also on An Alt-Az mount, so field rotation is an issue as well...

I don't really notice as I can compare mirror images (something to do with an organic chemistry background). I'll try to flip and rotate in future.

Cheers
Stu
