I'm continuing my attempts at overly dramatic Lord Of The Rings titles.
When you work so hard on an image you have to name it
something!
This data was collected in the month of July 2022 over many nights. NINA makes it easy to add a target at the end of a night when there is still time before the sky brightens, and the custom horizons allow NINA to know when objects appear and disappear for the night. Without NINA and the telescope covers I would not be able to collect 30 hours on a target with relative ease.
There is no comparison between Ha, SII and OIII in my data sets. I understand that Ha is the strongest signal, but I wonder if the filters make a difference too. In Bortle 8, the Baader 3.5nm Ha filter is amazing. Ten hours or so at f5.3 will result in clean data across the whole field. My Optolong SII 6.5nm filter gives me a decent but not great signal to noise with 10 hours. Lastly my Baader 4nm OIII filter gives me brutally noisy data after 10 hours. I think I may have one of the early versions with the filter peak at the wrong frequency (as per the many Cuiv The Lazy Geek videos on this topic). My most immediate gear replacement will be all filters. I have been told the Astronomik Deep Sky RGB filters outperform Optolong RGB (especially for bloated blues). I also want to replace my Optolong SII 6.5nm with a new Baader SII 4nm for f3.5 to f10. I don't know what to do with the OIII filter - it is difficult to justify the cost of Chroma filters (a 2 inch circular piece of glass with a coating applied costs $1,300 USD !!! WOW)
