I missed the best of the GRS but it was nice to see what it looked like - it's been a while since I've been able to image it in better than average seeing.

There appears to be another spot approaching the GRS at the same latitude as the LRS did - it even appears to be the same size as the old LRS but it's just not red/orange in the middle.

12" Newt, 5x powermate, DMK21AU04. 30fps for ~52 seconds in each channel.

There may be more from the session coming later but these are probably from the best of the conditions.

Thanks for looking.
Hi Mike,
Great work, best I have seen with 5x very sharp and not over processed.

Reworked my 3x from the 30th. Took your advice with the curve adjustment. Used the curves adjustment within Astra Image Pro to lower it a bit, made a major difference, not up to your standard but I am working on it.

Regards
Trevor
