Hi Mike
I mounted the TEC finder base with those two screws in the
GT tube. Fit perfectly. Now I can use the TEC/AP finder or
MRF in that base on the GT. I like the idea that the finder
doesn't have to rotate with the focuser.

Wes, I believe this is a good solution to the two screws on the tube. I would expect AP to at least but a finder base there so that the two screws don't spoil the look of the OTA.
The peel off lens cap can be improved though. Even the cheap Meade 127 APO triplet has a screw on lens cap. Not that I like that, but it still look better than a peel off cap on a nearly 6K AP scope! The TEC lens cap has a really nice touch to it.
Otherwise, I think the GT is a really exquisite scope in the sense that it can be break down for portability.

guys, what do you think would be a resale value of the Gran Turismo? This scope is quite new, sells for $5675 by AP.
Any idea what would be its resale value?

How does the color correction compare?
--------------------
18" Dob
12" SCT
8" TMB F6 + Chromacor
6" F6 APM/LZOS Fluorite triplet, 32", 32lbs
2ea. 6mm singlets, one blind

Ref: Color Correction
I see the color correction of the 130GT as being excellent
so far; I haven't really cranked up magnification on Vega
or Sirius though. No color on any other star visible now
in the evenings to midnight and no color on the limb of the
Moon at high power (240x-330x). Jupiter is white with ex-
cellent contrast of the bands. Jupiter's color is all on the
disc, not around it.... Double Cluster has the Red stars
stand out easily. I can easily see the red/orange color of
Antares and its green companion. As far as Doubles are con-
cerned, it easily splits Nu Scorpii when seeing is steady.
Using high power terrestrially on pine tree needles against
the blue sky in broad daylight shows no purple haze (300-400x). So, color is not an issue for me.
BTW I viewed through a TEC160FL for comparison so I am
familiar with excellent optics as you are too, judging by
your equipment list.
I'll try to answer any specific questions, as this was a very general answer. And, the view of the Milky Way impress-
ed me by the sharpness and clarity and fine detail visible;
I believe a better indication of the excellent optics.
Clear Skies,
Wes
ps. I view stars and planets etc in focus

Not only Nikon, but other camera manufacturers as well. This definitely isn't something that was invented by TEC. This might be new for telescopes but lens covers like this have been around for a long time.
