How to a Use Dobsonian Reflector Telescope

This video is aimed at new astronomers who need some help on getting started or returning astronomers who may have forgotten how to use a dobsonian telescope. So if you are of the latter, this is going to be a good refresher.

1. Inspect & Assemble Telescope
2. Collimate Telescope
3. Align Finder Scope
4. Observe Through Finder Scope
5. Observe Through Eyepiece

If you are just starting out, I highly advise that you first practice observing larger and brighter objects like the moon because it will be easier to locate.

Sir excellent explanation. I did not even consider that observatories use the same type of Mount but only larger. I’m thinking about it now the Dome swivels left and right and the telescope goes up and down. Wow the lightbulb just went off in my head.

I have a 6×30 optical finderscope (also from Skywatcher) , and because it only has 2 screws it is very hard for me to align it to the main tube, any hint about that?
It is this one : https://www.alphacygni.com/6411-thickbox_default/buscador-skywatcher-recto-6×30-con-soporte-blanco.jpg

Thanks for your video. I’m thinking to buy a telescope like yours, and I’m intricate about the black piece between the two OTA pieces. What material is it and how you put it. Thank you very much!

I was going to comment on this last night and got side tracked. We need more videos like this so beginners can see the working ends of how a telescope like this works. Great Video and very informative. Astronomy is the most amazing thing and with today’s technology and the more advanced scopes with larger mirror cells or glass; the heavens are limitless.
