Wide View for Testing a Telescope

We were having trouble with our Celestron CS5 f/10 telescope, it is not fast and collecting a decent amount of data takes hours.

We have an Orion 80mm f/5.0 Refractor that came with the guiding kit. We decided to give it a try as imaging telescope.

We started with 30 seconds at 1600 ISO and 17 light frames. Since this is just for testing purposes, we didn’t use any flat, dark or bias frames.

Considering this is just a $130 telescope, it works much better than we expected. We are planning to get a better refractor telescope to replace our slow Schmidt-Cassegrain telescope.
