It’s one of the late Charles Riddel’s last mounts, a version 2 FTX. Best alt-az available IMHO...though only on the used market now, and rarely at that.

Just picked up my TEC160fl from UPS this morning.  Excited to open up the box when I get home from work and get it under the stars.

Those of us who have TECs understand how excited you must be.  Congratulations!  Looking forward to your impressions.

Very nice, Mike!  You're going to love the 3.5" FT focuser if you've never used one before.

Absolutely gorgeous scope.  I am sure that scope is going to knock your socks off.

Hopfully I can get it mounted this weekend and get a clear nite to try it out. This truly looks like an amazing scope.  I just need a clear nite to try it out.

TEC lists the weight as 24 lbs.  It is very front heavy.  I will be retiring soon , so it was a retirement gift to myself.

Ok I’m retiring in June and am thinking about a retirement scope. My first thought was a mewlon 210 but I keep thinking about a larger refractor. Specifically a tec 160. 
 

not as much cool down 

no collimating!!!!!!!
better lower power use with wider fov 

can go almost as high as mewlon on great nights

no diffraction spikes

no mirror flop

almost as much light as 210 when secondary obstruction included

excellent optics better or as good as mewlon

ota 24 lbs + rings finder etc still under 33 lbs

will fit alongside tak fc100 on ioptron az mount pro

probably a lifetime scope

costs four times as much :-(

 

is my reasoning sound ??

Completely good IMO.

 

The effective difference in light through put to the eyepiece is only ~20% +/-.  Nothing dramatic.

 

But, have Yuri shorten the tube by 1" or so, use the Baader BBHS silver diagonal with T2 quick changer top and get a pair of those Zeiss 30mm bino-viewers from Denis.  Just one look at the double cluster with that configuration via a set of 24mm Pans or APM UF's will completely-bowl-you-over (!).  And then there is the 160 FL with a 41mm Pan on the Pleiades...... and M31....M81/82.....M33....

 

That low power, wide field punch is one thing the Mewlon, an excellent scope, just can't manage as well.

I own a Mewlon 210 and Tak TSA 120 now and have owned an AP 155 and AP 152 refractor in the past.

 

 

You are generally correct.

 

Just a couple of thoughts: The Mewlon will just edge-out the 160 on smaller deep sky objects. The Mewlon is more portable and compact. The Mewlon will always be fussier than the refractor with the refractor better able to deal with thermal and sky and seeing conditions.

 

The refractor will most likely edge-out the Mewlon on planetary with the lunar views being close.

 

Visually they will be close so it really is the ergonomics of these 2 scopes that should be considered: cool down, portability mount size, cost, field of view, etc.

 

If cost and portability are not issues, I would opt for the refractor. When portability became an issue for me and I downsized (selling my larger refractor and mount), I went for the Mewlon but also added a smaller refractor ( the TSA 120) to keep some of those refractor attributes.

 

Bob

the AZ Mount Pro might be a little overwhelmed with the a TEC160(FL). If it is not the weight its the moment arm, thats just too much and everything will need considerable time to dampen down. My TEC140ED goes well with the AZ Mount pro. But put the same weight in form of the LZOS130 f/9 on it, and its definitly more prone to vibrations. What I have yet to try is a more fitting tripod than the standard 2" SW tripod with the Mount Pro. An AZEQ6 in AZ-mode might be an alternative though.

I plan to use the upgraded mount NOT the 2” tripod

I’ve got the Az Mount pro, and while I really like it, I think think the 160 would be a bit much for it.  The 140 is the upper limit for the mount to comfortably handle I think.

From my reading the most stable is with the tripier I’m sure this in my future.

Although not made to the same standards as the top tier mounts, the AZ-EQ6GT is the best for my various setups and has performed well for several years......

the pictured binoscope weighed in at 17Kg with a similar weight on the other end !!

 

Edit: the key to these setups is actually the tripod, the stock SW GMT128 is simply not up to the task, the Berlebach Planet, Losmandy FHD or in my case the Tak TMT70300 with a 1000 lbs weight capacity, make for the best setup..

 

Edit 2: Seeing this is a TEC-itis thread here is a pic of my modified SW tripod (new longer and stronger tubes and DIY Kunama brace)

Listen to Matt. The AZEQ6 is very capable. See the attached picture showing my CFF185 on an AZEQ6 on a Losmandy tripod. It is a scary set up considering the ota is 10x the cost of the mount. However, it works very well!
