My TMB/LZOS 130 F/9.2 on the T-Rex mount:


How does the Trex handle that long moment arm?

How does the Trex handle that long moment arm?

Brilliantly. Just so much better than any other mount that I've had the scope on. Vibration dampening is 1 second or less even at 370x. Given the compact design of the T-Rex (no counter weights needed either) you do wonder how the design manages to do what it does but the stories turned out to be true. Slow motions are very smooth and intuitive to use as well. The mount just gets on with its job leaving you to enjoy the views.

 

I count myself lucky to have found one of these in the UK smile.gif

A sturdy and stable mount is definitely a force multiplier. Looks like a great scope on a great mount.

My modest GnG setup SW72ED on AZ5  (complements my 10" dob).

 

72ED is also used for terrestrial viewing  (45 degree prism diagonal + zoom).

 

Don't have many fancy stuff, only 2 scopes and 6 EPs  (am pretty much minimalist).

Thanks.  Very very stable, no shaking, nothing.  Solid at high powers.  AZ5 has 5kg capacity, and the 72ED + diagonal + heaviest EP (Delos 6mm) + RDF = 2.6 or so Kg.  Thus, half the AZ5 capacity.

 

Before I had SW80ED (my avatar picture), which was heavy with 2" diagonal and EPs, almost approaching the 5kg limit.  And 80ED had unusually big OTA (similar to 100ED OTA diameter), thus such unnecessary heaviness.  That combo was shaky and was stretching the mount, almost impossible to focus due to shake.  I sold the 80ED.

 

Now I am happy how this GnG works, both for astro and terrestrial viewing.

It’s a Vixen APZ advanced polaris alt/az mount. Very good and solid. Also very good the slow motion manual controls. It can be motorized. With the Vixen SXG tripod I think you will have one of the best alt/az mount available. The only drawbacks are weight (but still quite portable) and high price.

My younger brother was given this telescope as a gift back in the mid-70s. Sold through Montgomery Ward, it is a 60mm f/11.7, and nothing special as the images through it are like just about every other scope of its type produced during that timeframe. It came on a wibbly-wobbly alt-az mount that so many of us have struggled with in the past. 

 

The scope came to me after he went to his reward and I passed in on to my neighbor, a woman in her 70s who is interested in observing the planets and Moon, who joins me on any occasion when conditions are good for that purpose. Vixen is currently blowing out their 70mm alt-az refractor at a low enough price for me to get one and give it to her. Using it two nights ago, it proved much easier for her to use, which I am relieved about.

In my youth I had sth like this! Mine was a Tasco 9T with same shaky mount and tripod.

What do you think about the optical quality of your vintage refractor? Is it quite as good as the achromats nowadays, or even better?

Well, I have not looked through any current-production achromats and so cannot render an opinion regarding quality of views, and I did not set up a side-by-side with my neighbor's new Vixen, that would have been awkward. Moreover, I have no idea if her scope is representative of low-end achromats produced today, but I should think most scopes are built to a price point and their performance would  probably reflect that. 

 

I have another 60 f/11.7 from a different Japanese mfr but probably the same time period, and it throws up images which memory tells me are quite similar. Perhaps I will look at having them together for a comparo soon. This kind of scope is fun to use on occasion, even with the 0.965" ep, but we're all spoiled by the cornucopia of high-end optics available relatively inexpensively, these days.

My ED127 is a gen 1 which has the "flip over" dew shield. You take it off...flip it over and put it back on....before you put the scope in it's case.

 

The "This End UP" sticker covers a small "ding" I accidentally put on it when I bumped it when taking it off the mount in the dark.

Thanks Matt. They give me a spread of focal lengths for imaging and the big one will be nice for viewing planets.

I'll be keen to hear your thoughts on the SW150ED, especially compared to the iStar 150 F10 which I thought gave great views for a large achromat.

I am looking forward to the planet season to test out my 152mm beast as well as trying out the brass monster Skylight AR101 F15........ grin.gif

 

as for the "value segment" ....... I am amazed at the quality of the scopes from the value segment, the performance gap has got to the point where it really doesn't matter in visual use.... 

if Chris had decided to keep the LZOS optics to himself I think I would have been perfectly happy with the APM 140mm F7 ED......

The 150ED figuring seems excellent and visually there's no obvious in-focus false colour. It does a better job of imaging than I thought it might too. Planets should be interesting.

 

One thing I like about APM is that they provide the design strehl graph for their ED doublets, something I'd like to see for the Skywatcher.
