Well done Greg

- looks like that 180's a keeper!! 15 hours is well into mega data territory too - hats off to you.
Can't help feeling though that with 450 mins Ha you should be able to bring out some more contrast in the streamers without adding noise/artifacts. How are you blending in your Ha?
Yes, I'd say the baffling is pretty good not having to deal with flare from Alnitak. Interesting what you say about masking the chip and blackening the edges of the filters - haven't heard that before. My Tak showed 4 greenish semi circularish refection flares - but they were fairly easy to process out.
Again, well done - look forward to more!
Cheers, Marcus
