I revisited an old favorite for my first quick test with my new Takahashi FSQ-106EDX4.
23 x 600 second integrations, Baader Hydrogen-Alpha filter, FSQ-106EDX4 @ f/5, SBIG ST-8300 with FW5 filter wheel, processed with PixInsight.
I have a post that shows the internals and disassembly of this camera and filter wheel here:

I got a second amazing night for imaging and despite it being a Tuesday I couldn’t resist having a go at some RGB data and eating the lack of sleep. I combined the RGB images with the hydrogen alpha data I collected on Saturday to get this image.
SBIG ST-8300m camera, AstroTech AT65EDQ 65mm f/6.5 refractor, Astronomik 1.25″ RGB and Ha filters, Orion Nautilus 7×1.25″ motorized filter wheel, Losmandy G11 Gemini-2 mount.

30 x 5 minute Hydrogen Alpha sub-frames for luminance
20 x 5 minute sub-frames for each red, green, and blue filter
30 averaged darks
30 averaged bias frames
Total of 7.5 hours of exposure time.
