First light, new mount and Ha filter

[Datalord]

Last weekend I got a used 10Micron GM2000QCI delivered and switched it in for my distrusted old Celestron CGX. I mounted my 11" RASA on it and for the first time tried the f/2 Ha filter from Baader with the QHY247C camera.

I'm well pleased. This is a stack of 14 images, 180s each, for a total of 42 minutes. No calibration frames at all. Just the stack, a quick AutomaticBackgroundExtractor, arcsinh stretch, nothing else.

A very nice image, 42mins, a mere flash in the plan for you. Wish I could do something, weather is terrible out here, over 5 weeks now without a decent sky.

Haha, yes, usually 42 minutes is barely enough to get started on my Spain rig. But this one is from my light polluted back yard in South England. 

Every. Minute. Counts!

That bodes very well... congrats on your new purchase - a used 10micron... I thought those were in the realm of hens' teeth and rocking-horse dung!

No, it's the CGX that's in the realm of dung...

That's a lovely set up.  Good to see that everything seems to be in order.  Look forward to seeing what the RASA delivers for you.
