Great shot Ray! |
thanks Rob. Thought of suggesting Slightly Fortuitous Astro-imaging, but decided against it.

Hi Louie. have not yet tried 1 second subs yet, but it is possible with bright targets. The bias noise was not too bad and I used masked low pass filtering to subdue it - in future will have to take a new bias set when doing ROI imaging - it should allow more effective removal of the residual noise.

Thanks for that Rick. It is a darned small object and 0.5 arcsec sampling is getting into the realm of the limiting resolution of a 10 inch scope. However, looking at what happens with planetary imaging, there should still be some gain in detail out to about f20, so there is still way to go before all hope of extra detail is lost. will be an interesting experiment to try it with a 2x Barlow - might not be fruitful, but interesting.
