NGC 2359 aka Thor's helmet Combination or rgb stars using the Optolong L-pro and dual narrowband using the Optolong L-Ultimate. I made a lot of errors with this night including incorrect backspace as I added a filter wheel to utilise the filters and to get ready for when I will go the mono road. All put together and stacked in Astropixel processor. Processed further in Photoshop including removing the stars and adding the rgb stars from the Optolong L-pro data. StarXterminator and NoiseXterminator are so useful for this. 1 hour RGB at 60 seconds each and 4 hours with the L-Ultimate at 600 seconds each.
