It's a repurposed Astro-Physics 80mm x 900mm achromatic guide scope (Mechanicals by Nihon-Seiko) on a beef-ed up Porta II mount. The finder attaches to the dovetail which allows me to use it with other OTAs on the same mount.
Now if last night's snow would just melt.....

Im not really sure if its "thee" coveted version
What i can say is i just had a few good nights with it to assess it. I have heard conflicting reports on this scope some same its a true APO some say its a Achro some say it performs like a doublet.
This version i have has not be tampered with a i can say from my view its a very nice. At 50x per inch it works at ease 160x mag. even at 200x 63x per inch it works great!
I will tell it like it is about the CA, have had a few smaller achros/ED doublet and looked thru a few APOs, I can say its most likely a older triplet APO.
At 200x on the moon there is virtualy no CA and when looking at Jupiter there is a bit of CA but more a slight burgendy/green depending on the in and out focus. There are no purple halos!
So i think its a OLD triplet with old glass and is not a triplet by todays standards and acts more like a doublet
Being picky about CA i can say that this scope is more than acceptable.
I picked it up mainly for a traveller scope and i think it will be a great travelling partner easily mounted on a tripod

Really cool to see a GEM set at -- what? -- 20 degrees or so.... I'd love to get back that way with a fine scope and look South! Thanks!

Good Eye! We are about 20.5 N here. The counter weights just clear the leg. It is funny but the classic refactor "pose" on a GEM is always around 40 or 45 degrees, so it does look a bit off at first glance (but some of the southern stars and deep sky objects are awesome - Eta Carina just gets up 10 degrees here but is a great sight for the brief time it is visible!)

I'm happy with the views these allow me to enjoy.

The TOA 130 IS a big scope for a 130 apo. With accessories it comes in at about 30 lbs. But the IEQ 45 can handle it nicely. It has a rated capacity of 45lbs (maybe a bit optimistic) and for visual it works quite well. And with the tripod legs extended, the eyepiece height is just about perfect. The IEQ45 is also lighter the other GEMs with the same load capacity which is why I choose it. So I think for a visual observer it is a good choice for this scope (for the times I don't need tracking I plan on getting a discmounts DM6 and save even more weight!).

My TMB92L had its first white light yesterday. I'm eager to get it under the sun again.

Of course so did the clouds...
First light will have to wait for a day or two.
