After shipping back my CCD for some TLC last week I put the 60Da on the back of the RC8 cos I will go stir crazy if I don't do something whilst waiting for the next couple of months.
I checked all the collimation after installing a tilt ring and had a go at this gorgeous object just to make sure there were no major issues across the field. Its a smaller sensor than the STL so less grief on field curvature and as such I didnt need to crop. That was a very pleasant surprise.
Not a huge amount of data, the idea was just to check everything out so...
14 subs @ 180 sec, ISO 400.
There are a few compression artifacts on the attachment so Full Frame is
NGC5139 Omega Centauri
