New TMB 92 Light, same 4.5 star optics.
      #2906650 - 02/03/09 10:14 PM

The stellar review in Sky and Telescope's March issues has kind of opened a box. When I was talking to Tom about the 92, we had talked about it from an imaging standpoint. Addressing back focus and large chip cameras. However, it has become clear to me that people really want a visual scope in this size and could care less about the imaging aspect. So here it comes.

The TMB92L proposed features.

Same exceptional optical system S and T called virtually perfect.
90~95mm OD tube.
100mm of backfocus. The tube would be around 15" bow to stern.
2" crayford focuser, maybe 2.5". We are trying to save weight.
Possibly not baffled, but flat black pebble painted interior or flocked. This has worked for years in other high end scopes so I don't see why it can't work on this one. I have some fears about the light cone and the baffles may just prove to be useless in that size tube.

Best part. Price....$1495ish.

We hope to have a sample or two at NEAF.

That is one sweet deal, Mike. Looks like the TMB booth will be really busy.

WOW!!!

This is a good news to me to have a TMB 92ss for imaging scope and visual scope. Do you have a dedicated field flattener for this scope yet? When to finish?

Thanks

Is this a 2" or 2.5" feathertouch focuser Mike? If this can be done for around $1500 I definitely would be looking to get it

Sign me up!

I would consider this for a travel rig, so I support a flocked/thinner and lighter tube over a fatter one with baffles. The flocked tube in my TV102 works pretty well.

I don't think it will have a Feather Touch at all. To go with a FeatherTouch will put the scope at around $1795. We are trying to keep the price reasonable as well. It is a fine line since the 92 is priced so well with the focuser it has currently. One of the few ways to drop the price is in the focuser. The optics will cost the same, and the tube will be a little less expensive. It all comes down to the focuser.

My flocked TV-102 has served me very well. While I like FT focusers, I don't consider this a deal killer. The folks who gotta have one can probably upgrade.

This sounds like a very nice travel (or GnG) scope, with a "just right" aperture.

See you at NEAF.

The 90mm triplet market sure is getting interesting!... and a great bargain, to boot.

It's always good to see another premium-grade small APO with a sub-premium price. The Feathertouch would be nice, but it would also jack up the price like Mike said. Anyone who really wants the FT bad enough can always get one afterwards and retrofit it, I imagine.

I've got two scopes with FeatherTouch focusers and an AT-90 with the stock focuser, which I believe was used on the early TMB scopes. I don't use any of the scopes for photography for the present. The FeatherTouch focusers are very nice, very well constructed, and very smooth. The focuser on the AT-90 also is very well constructed and almost as smooth. The knobs are a bit larger and have a slightly different tactile quality, and to be honest, I actually like the feel of it it more than the FeatherTouch focusers. From a photography standpoint, the AT-90 might be subject to a bit of flexure, but apart from that, it is a very solid, very well constructed little beast. So I see no reason why the absence of the FT focuser on the TMB92 should detract from it's value.
And off topic just a bit, the optics on the AT-90 are excellent. This scope has not attracted the attention it deserves. Even at the original price before it went on sale, it is a steal.

Just a few comments, questions:

I think a feathertouch would be well received even at the higher price. It's still cheaper than the original 92SS, and would be high end front to back... Perhaps a choice?

Why 100mm back focus? It seems that 2.5-3" works well for visual 99% of the time.

So- sliding dewshield and no tube extension, right?

Lastly- my vote would be 95mm O.D. 90mm O.D. might look funny having a fat cell in front of a skinny tube...

I want one, then I again I want alot of scopes. I'm looking at picking a scope up at NEAF and this might have to be it.

100mm gives people that want to image with the scope a good chance.

Sliding dew shield and not extension is correct.

THe 90mm is a standard in the industry. That means no special tube rings or exterior accessories. The WO and SV scopes use a 90mm tube right now.

I have to vote for the NOT Feathertouch focuser. I do not believe the added expense makes sense, and the asian focusers are just fine.

I have to agree the Asian focusers are more than adequate. And if the goal if this model us to reduce price along with weight, that is the way to do it.

On the barrel and baffles, there would still be dome room for a few baffles once you were about 70mm from the front of the tube. They wouldn't be very deep, but they would still be effective. Then again, a well flocked tube may be a 99% solution if the focuser draw tube is well done.

Yep. The tube is going through final design and I hope to have a solid price shortly. They have two cells to build the scope around and it will be at NEAF.
