What could be causing it, and how can I fix it?
The diffraction pattern around the bright star is consistent with petzval scopes, and I have yet to see the rainbow, however.
These are 60's exposures, 30 each RGB stacked and calibrated with 30 flats, 30 dark flats and 50 darks.
Processing is as follows:
Stacked/Calibrated in APP
PX Processing:
Slight Dynamic crop
ABE
BlurX
NoiseX
SPCC
Set up as follows:
AP mach1
Tak 106EDX4
ZWO 6200MM pro
Astronomik Deep Sky filters
Any input is much appreciated.
Much love,
Kevin.
