Making a DOB base will be phase 2 once I can verify if the image quality is worth while. When i get some clear skies (hoping this week) i will test it on a planet and see how it looks. If the optics are OK then i will plan on a dob base.

Seeing as it only comes with a single EP i have ordered an Orion 7.2-21.5mm Zoom which will give a fair amount of viewing options without the need to change EP's. the EP should arrive within a week

Managed to get it under the sky tonight
The image quality is not so bad for such a little scope with the 25mm lens i could se Jupiter and it's moons. They were small but viewable. The next open sky should be Sunday and by then I will have my Zoom lens so it should provide much better images.

Not bad for $25

Ok after getting a new EP the images get way blurry even with the one it vame with it was not great. After inspecting the primary mirror it looks like it has some light marks on it like it was cleaned by rubbing

Any ideas where I can get what I think is an F8 4.5 inch primary for this scope

Figured out what was wrong. Both of the mirrors have super fine lines if the silvering missing. Looks like the bad attempt of cleaning by the original owner ruined the silvering. I removed them yesterday and have shipped them off to be recoated.

I dont think the surface is damaged in any way but when looking at the back of the mirror with a torch shining on the front face I can see the missing silvering

I removed them yesterday and have shipped them off to be recoated. It will cost me about $70 to have them stripped and recoated..not too bad

Sure looks that way. I should get them back with new surfaces in a week or two. Then the snow may be gone and the skies will be clear again

I also did some measurements and the scope is a 4.5 inch f/6

Which should still return some nice images with the new silvering
