what are the advantages of the telescope that you use? thanks
Compared to my SkyWatcher Esprit 80ED f/5, the TS-Optics 8″ f/4 UNC Newtonian gives cleaner star colours with my filter set and tighter stars. The focal length also provides more details in galaxies and small nebulae. However, the SkyWatcher Esprit 80ED f/5 gives a larger field of view and is lighter and more portable and easier to set up.
this is a very good sight
