Thanks, thats pretty close, just about 1.3lbs different. Does yours have the R&P focuser? This one is a linear track not the R&P.

It's the R&P with the fine focus knob. Nothing special but good enough. Gerry

Do you have any closeup pictures of your focuser?

No I don't but it's just like the ones in the ES ad for the 102.

That's a beautiful looking scope. Hope that you get to try it out soon.

Having owned the Big Brother 127, may I suggest yoou shim the rings inner faces with a thin self-adhesive felt layer - even done fully tight, my tube still slipped quite easily in the rings, both in rotation and fore/aft. All mine needed was 1/2mm thick shim felt.

Glen- As far as I know ES is using the same focuser on all their refractors. I'm not aware of any design changes. Gerry

This one is a linear track crayford focuser. Designed to handle more weight with better holding power. I will take some closeup pics and post them in little bit. It does not have the power of the R&P but more than a standard crayford.

Yes that's the one I have. Couldn't remember the correct term. They call it a Crayford. It's okay but not like the Crayfords I have on my other scopes. Gerry

My focuser looks the same but mine doesn't have the smooth plate . Mine has the R&P type grooved track. Maybe it IS different. When I can tomorrow, I'll take a pic. Gerry

Congrat's on the new scope, I have the aluminum tube version and it is a great scope.
At the SCAE event last weekend I spoke with Scott Roberts for ES and they said all CF APO scopes come with the R&P focuser, the 3 they had on display all had them.
On the ES website they also sell a linear and R&P focuser separately.

Thanks for the clarification. I was confused about that. I have the "Essential" version and love it. Gerry

In picture two, what do the two thumb screws do. You need at lest four to adjust alignment on the drawtube.

I'm really liking the linear focuser on mine!

I believe they're tension screws for tightening the focuser for heavy eyepieces or cameras. Never needed to play with them.

Nice shot of the front lens. Mine was pretty dusty when it arrived, though the scope looked perfectly new. The dust was on the back and possibly some between. Has anyone sent one back for cleaning? Do they do a good job? I know a bit of dust on the lens isn't supposed to make a difference, but your looks much cleaner.

Conngrats Glen, Is that a Pioneer 77 or 88 in the backround?

My lens was clean when I got it but after using it a couple of times there was some pollen on the back lens inside the tube (I think I left the diagonal uncovered). I took the focuser off and shot some canned air up the tube and it cleaned up nicely. It makes no difference performance wise but when a scope is new you like to keep it that way as long as possible. Explore Scientific has a cleaning and collimation service if it gets real bad. Gerry
