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](https://amzn.to/2SUqxzT?ref=macobservatory.com)mount,[ZWO ASI1600MM-C](https://amzn.to/2SV5ahO?ref=macobservatory.com)main camera,[ZWO ASI120MM Mini](https://amzn.to/2SYC0OX?ref=macobservatory.com)guide camera, ZWO Mini Guide Scope,[ZWO 8-slot electronic filter wheel](https://amzn.to/2LU50qe?ref=macobservatory.com)with LRGB and 5nm narrowband Astrodon filters, Moonlite focuser,[Baader Sky Surfer V](https://amzn.to/2LVraZk?ref=macobservatory.com)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. ](https://storage.ghost.io/c/8d/3a/8d3ae6c9-185e-49c7-b8a6-36d44545d9f9/content/images/2026/03/vk2labdthtsj_1824x0_wmhqkgbg-format-original.webp)

![ 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. ](https://storage.ghost.io/c/8d/3a/8d3ae6c9-185e-49c7-b8a6-36d44545d9f9/content/images/2026/03/fvdcl5qlpxs6_1824x0_wmhqkgbg-format-original.webp)

![ 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. ](https://storage.ghost.io/c/8d/3a/8d3ae6c9-185e-49c7-b8a6-36d44545d9f9/content/images/2026/03/o7obyj5i5zip_1824x0_wmhqkgbg-format-original.webp)
