hey Garry do you know who made them for telescopics? or who was the mirror maker? I know they came as a gold aluminum tube in 6"to 12"

I owned one back in about 1985.  It was an 8" F/5 with a small secondary (1.52") and a 1 1/4" focuser.  The scopes were advertised as 1/20 wave peak to valley with enhanced aluminum coatings.  Best set of 8" optics I ever saw.  The star test was perfect and color contrast and detail on the planets best I've seen in an 8" Newtonian.  The scopes were not available for that long, but I wish I had kept it.  the rumor mill had it that the scopes were produced at JPL labs by an employee on their high end equipment.  The story went that that employee moonlighted selling scopes that he produced the mirrors for with JPL equipment.  Not sure how accurate the story is, but the one I owned had the smoothest Newtonian optics I've ever seen.  The only issue I had with the stop was that the secondary was hard to keep in alignment.

I bought quite a few ATM parts from Telescopics back in high school in the late 60's. Great company. Never had one of their mirrors though.

I would love to see a picture if anyone has one.
Back in 86😂, I had a Coulter Odyssey 1 at 15 years old!
Long story short, somebody had one of these puny 8” dobs that was in some way outperforming my cardboard light bucket. It obviously left an impression on me.

The pic of my Telescopics Newtonian,,, slightly upgraded from what the scope looked like back in the early '90's..

 added feathertouch many moons ago

 added telrad

 added a larger secondary and I use it for imaging & viewing

 

But stayed with the same tell-tale sign of the gold anodized thick aluminum tube,,

viewing quality excellent once everything cools down

imaging quality same as viewing,,,

not bad for the 8" f/5 newt..

 

image of helix was done using canon 60da and pic of helix was taken using my cell phone to shoot the laptop screen,,

5x 200sec. exposure time

In late 1988 i placed a order for a 12.5" F/7.5 Newt from them. Took over 2 years and had to get SKY&TELE on their butts to get the mirror.  They went out of biss soon after.
