The core came from a short exposure taken last summer.
Calibration in IRIS, Processing in Photoshop.
Very much a work in progress. Hope to improve on this through the summer by adding more exposure.

Nice work. I look forward to more.
The background is very dark and I suspect that there is even more faint detail that you could extract. 20 min exposures is only a dream for me. Any problems with noise at that length? I might also suggest ISO 800, particularly with that filter. What is your estimate of the extra exposure needed when using it?
Cheers
