I would hope shortly, but I don't have a solid date yet.

Do we have an idea of the weight of this scope?

We'll know when we get the production prototype in for testing.

I believe Mike has said it will be somewhere around 3kg, probably a little over. Looking forward to seeing the prototype!

A big difference between the TMB92SS and TMB92L is the weight, due in part to the L not having a collimatable cell.  Will the AT92 have a collimatable cell?

 

I wonder how this triplet design would compare with the equally-fast fluorite-doublet design of the Borg 92FL?  I note that the Borg does not use a collimatable cell, yet it was designed as a portable 'scope and presumably able to withstand the inevitable bumps and knocks, so maybe 90mm-size is in the goldilocks range of not requiring complex and heavy cells?

Bump...   any further word on...

   Prototype arrival?

   Weight?

   Still on schedule?

I am looking at the AT 92 triplet as a potential upgrade of my current 80ED scope. Eagerly waiting for some news - testing or otherwise to get some more details. Thanks all (and Mike & Fred) for their generous contributions here ...... Anil

Mike, to clarify... does on schedule still mean Q1 2018? And if you could say, would you say sooner or later in Q1? Forgive me if I'm mis-remembering. Thanks!

We were hoping for end of January 2018.  I asked for an update yesterday, but I have not made it into work yet to check my mail.

The sample should be finished this week.  With any luck we will see it next week.

Exxxxxxcellent. That is very very good news Mike. I may fight off this Takitis after all! End of January is honestly not that far away...

We have the original TMB92 here to test it against and verify it is all it should be.

Hot business. Are you going to do a full optical bench to compare them, as well as a real night under the stars, or just an optical bench? Or how are you going to compare them? And... one last thing, when you get the time, I would also love to get some final measurements for LxWxH, as well as the weight. Thanks Mike!! Really looking forward to seeing some photos and hearing how it compares to the original.

We will do under the stars.  When we get it here we will take all the measurements and post them.

Just curious as to whether there is anything new to report. No pressure. smile.gif

I'm also eager to hear! I'm especially curious about how much it weighs. If it's not too much trouble, could you weigh the dew shield and maybe focuser by themselves? Trying to figure out how much weight I could save if I modded it with lighter materials, to maximize its portability for travel.

Being that it's a rainy night in Georgia, time to give this another bump. smile.gif

 

Has the sample arrived, and if so, was it tested and deemed satisfactory?  Any specs yet?

 

Thanks!

It was at .94 Strehl. They are continuing to work on it so it hits the .95 minimum. I also assume finishing up our 102 and 60EDs have gotten in the way.

Mike, do you think the 102's are headed this way yet?

Jay, reading of your experience with the Borg, I was about to ask if you were still considering the AT92. :-)

 

Still have mine on order, and am hoping for an update as well.  My main concern is that they get things right, so a bit of a delay is not that big a deal.

I'm really curious about the weight honestly! Once Mike clears the optics I wouldn't worry too much about them. If it can be reduced to a low weight, only a little more than the 90FL, then it might be the better scope.
