Time to put my almost ruinous filters to work! Tried a different approach to capturing this. Normally I would dedicate an entire evening to capturing only one filter at a time. Unfortunately, as we all well know, this can mean getting a decent amount of data on one or a couple of channels, and then months of cloud to which the target can be gone behind a tree or ridgeline by the time you get back out there. I used one of the plug ins in NINA to calculate my filter offsets and its actually pretty good. I captured this by using the Lum filter to focus and used the focuser offsets to adjust for each filter change, allowing me to capture subs in LRGB order without focusing in between. I know the concept is well known but i was a bit dubious but thankfully it works a treat. Captured last Saturday night and a couple of hours clear sky last night. Processed in Pixinsight, no narrowband, no star reduction/removal, no SCNR green removal. Just as it is.
