A nice comparison especially for the beginner:

I like the fact that he and his local society donated 150 Orion 4.25" starblast dobs to libraries. Let's get some scopes out there!

He is the top expert in his own right. Ed Ting forever!

Great timing for this comparison as well, as a lot of scopes are purchased around the holiday period, and many of them end up not being used, or are junk.

This makes me really sad when you can totally make functional, inexpensive scopes. Like mini dobsonians or the ST80.

I think it was a nifty idea on Ed's part not only to equip local libraries with starblasts but also to equip them with zoom eyepieces.

Ever read Ed's report when looked through "Godzilla", one of four 36" Obsessions ever made.

 

It's great.

 

Clear Skies.

Ed’s video is accurate, clear, and succinct. Hope the mods will include it in “Best of Reflectors” or provide a link to Ed’s U-Tube Channel for future reference.

I like his strategy with the 8 for an every day scope and the 12 waiting there when he wants it.

I think 10" is my favorite size, honestly.

 

12" is too big for a solid tube dob in my opinion (it won't even fit in many vehicles).

 

8" isn't enough smaller than the 10" for the drop in capabilities.

 

4.5" pretty much sticks you with a cheap 1.25" focuser, and is awkward to use for an adult.

 

6" is a good size too, the longer focal length makes them more resistant to miscollimation and imperfect optics, so it's a good option for a cheap but effective planetary scope.

 

I mean all sizes definitely have their points and I wouldn't reject any of them but I think I like 10" the best and 6" next.

This was a fantastic video. I wonder- what does Ed think of Truss tubes? Does anyone know of a comparison of Truss tube dobs? This video is pretty great:
