I had a TEC180FL for several years and it was my primary  high end scope.

 

I did not use it visually very much but I did view through a few times. Orion was very detailed and overall the views were great but I think not as good as I recall with a Tak FS152 I had with a 22mm type 4 Nagler.

 

I used the TEC180 mainly for imaging and it was quite good for that. Although I found images from a friend's Tal TOA150 often showed more detail, sharper and more of the subtle things in an image. I also saw a test report of the TE180 and it seemed weak in the red channel. I'd describe it as a very good imaging scope but it could be improved. It seemed it was more optimised for visual.

 

I did have  scare once with the TEC180. One night when it was coldish (2C or so) the lens oil developed spiders veins. They went away when it warmed up and I never saw them again (several years). It was soon after I received it and I think it must have been from the air travel.

 

I have since had an AP140, Tak FSQ106EDX3 and a CFF105 F6. The CFF is one of the more impressive scopes I have owned. I prefer it over a TEC110 FL I had which was quite a nice scope.

 

So for imaging I would rate a TOA150 as slightly superior.

 

The TEC180 is fairly large and heavy and I would describe it as about the maximum I would want to have to handle to mount and dismount. I could do it but I was very careful as its a very expensive scope.

 

Greg.

Dave, I see you sold a 160FL a few months ago. Do you miss it?

Not at all.  When compared side by side with my 1990 era C11 it couldn't keep up in most categories - resolution, contrast transfer, magnitude reach.

 

Well, at f/7 it did have a wider field of view at 6mm exit pupil...and it is a better photographic lens but I'm not an imager so much..

Dave: Do you ever use a Celestron reducer - corrector for wider FoV? When I had a C-11 I preferred it most of the time unless I was looking at the planets, dbl stars, PN or GC.

No, never have.  I'm into exactly what you listed, and even in that order.

Dave,

I'm a bit surprised because you are a master with double stars. More in the sense of how the two scopes present stars.

Thanks for the compliment, Daniel.....

 

I'm sure you remember the Kruger 60 thread.  My C11 and my (now gone) Lockwood/Teeter 12.5" dob both had excellent success splitting Kr 60 visually.   Several attempts last fall with the TEC 160 came up empty....too dim.  I'm sure the 1.3" separation was not the problem.....

 

Etched in my brain is the view of Kr 60 in the C11 on a night of 10/10 seeing -- at something like 600x the two little spurious central Airy discs were there and the exquisitely delicate first rings were kissing...  

 

My C11 rocks!!!

 

Dave

Well, it's now official, the $3K deposit has been paid for the TEC160FL. A big thank you to everyone that has participated in this thread.

And in case you are curious, the lead time for the 160 is 8-10 months. Should give me plenty of time to figure how to run the G11G mount.

I just picked up the G11G mount at Losmandy today and made another side trip to pick up a used AT130EDT. Figured that I might as well have something to put on the mount while I wait for the TEC160FL to get built. This can be my training wheels to learn the mount and have some fun in the mean time :)

A short update on things. I'm #25 on the current production list. Serial number 160FL-025.

 

If anyone else farther up on the list has an update on delivery please share it.

I have #61 but from 2014.  Wonder if he starts at 1 for each year?

From a size/portability standpoint, the 160FL should be quite manageable, unless you have some significant physical limitations, such as a damaged rotator cuff, etc.  An AP 155 EDFS is almost the same size at 24 lbs, and no problem for me, although placing it into the tube rings is always a little nerve wracking!

I have a TEC160ED. I'm 56 and it's not a problem at all to mount. The problem I have, however, is looking at stuff near zenith. I almost have to sit on the ground. To solve that, I ordered a Lynak DL2 a couple months ago. It's due to arrive in a week or two.

I'm running the G11G with an AT130EDT until the TEC arrives. I've got the 12" tripod extension plus the tripod sits 7" off the ground on the wheelie bar. No more sitting on the ground or kneeling on the ground for me.

I'm #22, and just heard late summer of 2021 today.  We are probably in the same batch.
