+1 I own one & its never disappointed me.
I agree with the last 2 posters and suggest looking at the Explore Scientific First Light (Bresser in Europe). It's not so well known as it hasn't been out long. Here's a link: https://explorescien...ht-10-dobsonian
A couple of years ago I spent time in a number of shops comparing commercial Dobsonians soon after the First Light came out. In the end I bought an upmarket used Orion Optics UK (not to be confused with Orion US). However the First Light was my second choice. It's also highly thought of by a number of members of the UK-based Stargazer's Lounge forum who have used it in the field, and a search there will reveal several topics.
One of the most overlooked parts of a Dob is the mount. It's easy to upgrade the accessories, but not the mount. Therefore I feel that this is possibly the most important factor in choosing which make to buy.
The First Light has large altitude rings. Firstly, this makes it smoother. Secondly, it's much easier to carry the tube as you can use the altitude ring to do so. In fact an able-bodied person should be able to carry the tube in one hand and the mount in the other. Being somewhat disabled this allowed me to buy a 10 inch compared with only an 8 inch with makes without an altitude ring.
The Bresser also has tube rings. This makes it easier to balance different weight eyepieces and accessories, and also rotate the tube. It also means it's easier and less costly to convert to an equatorial mount later if you want to.
Some other features:
Primary mirror: made from low expansion glass so cools down ready to view quicker.
Focusser: A very good heavy duty focusser that you can easily convert at low cost to dual speed for easier fine adjustment.
Eyepieces: Only 1 but it's higher quality than with some competitors. Many buyers of the poorer quality eyepieces quickly upgrade them anyway, which of course adds to the cost
IMO, the First Light is well worth the small amount extra money. You'll forget this very soon but will appreciate the advantages for a long time.
That 10" ES is a nice looking scope. The rings plus large altitude bearings will make for a good viewing experience.
The only issue I see on that is it appears to have a single speed focuser. Not a deal breaker, but a dual speed would be nice.
There's a truss version at costco too, same deal with the focuser it seems.
Oh okay I really appreciate your comments!!!!! I should really consider the 10" ES and Explore Scientific! I am really learning a lot of variety of telescopes from all of you! Thank you!
