I’ve finally finished getting all the pieces together for this little scope. Pictured here is the William Optics RedCat 51 refractor telescope, Celestron CGX mount, ZWO ASI1600MM-C main camera, ZWO ASI120MM Mini guide camera, ZWO Mini Guide Scope, ZWO 8-slot electronic filter wheel with LRGB and 5nm narrowband Astrodon filters, Moonlite focuser, Baader Sky Surfer V red dot finder, and some dew heaters from AstroZap.
Now that everything has been put together I’ve managed to grab some imaging time on quite a few clear nights.
The SADR star region. That’s Sadr in the middle. I shot this as one hour of RGB on my ZWO ASI071MC-Pro camera, then managed to get a second night where I added 4 hours of Hydrogen Alpha data using the ZWO ASI1600MM-C camera. I then processed and combined the RGB data, and replaced the red channel with the HA data from the other camera. Then I cropped the final frame to the size of the smaller camera.
This is the North American Nebula (NGC 7000) along with the Pelican Nebula (IC1050). I captured this over 4-5 nights for a total of about 16 hours. It’s All narrowband, Hydrogen Alpha, Oxygen III, and Nitrogen II.
The Veil Nebula, which is a supernova remnant. Its circular shape is the expanding gas from a star’s explosion. Pretty cool. This was a quick shot, just three hours each of Hydrogen Alpha and Oxygen III filters.
