This is my first attempt at a narrowband project with my new-old Skywatcher scope purchased recently. End result is not too bad. Not as sharp as a $3k scope but didn't expect it would be but I couldn't resist 4.7 inches of glass for $300. Managed to get the ONAG on with 2mm of spare back focus..buckets! Think the image is horizontally reversed but decided I liked the blue on the right so that's my excuse. Slightly overcooked and a tad clipped but it makes a great desktop image on my computer. Enjoy.
