Hi All
I must admit it is nice to have some cloudless nights, now if we could do something about the sky glow, light pollution and poor seeing conditions it would be even better.
This is of the globular cluster M 3 on Sunday night which was as mentioned above, I had to wait until it got near to the zenith as too much either side appeared misty. This is first real attempt at globular clusters, I did have a bash at M 13 when I first started imaging with a Meade LX200 3 years ago, this attempt can be seen on my website http://www.imagingtheheavens.co.uk (http://www.imagingtheheavens.co.uk/). I wasn't sure about exposure times so did 30x1 minutes each for RGB all unguided. Just simple autodark subtraction was used, no bias or flat fields. It was taken with the Takahashi BRC-250 and Starlight Xpress H36. It is cropped top and bottom due to some heavy dark banding on the subframes, haven't figured that out yet. Overall I am reasonably pleased considering the seeing conditions. I have come to the conclusion that emission line imaging is a lot easier than RGB from where I live.
Thanks for looking
Best wishes
Gordon

Nice one Gordon. With Summer (and better weather) approaching, will be good to see how you handle some of the summer targets with the BRC. Looking forwarding to seeing more.

Hi Jase
Thanks for the comments, I am particularly looking forward to some narrowband imaging in cygnus when it comes over our house in the summer, but better weather? When was the last time you were in the UK?:lol:
The weather is so unpredictable where I live that I did more imaging on Sunday and Monday than I managed in the whole of February and March and still only got three images
Best wishes
Gordon

Very nice Gordon.
Nice pinpoint stars.

I love your set up, BRC 250....phew! and a nice looking solid mount to go with it...mate I am drooling!

Stunning work.
