Hi George,

 

Japanese scopes and optics are great aren't they!  The Altaz mount is nothing more exotic than a Skywatcher AZ4 that was disassembled and resprayed. It does look nice and just a little bit out of the ordinary with its altered colour scheme. It's actually quite an effective, cheap grab and go mount. When I bought it at first, some of the Chinese castings were a bit rough and catching in places. But when stripped down I filed away the roughness,  ensured that the original grease was where it ought to be, ( the Chinese just stick it anywhere), and reassembled it. It glides like butter now and I've even observed Mars at 474X with this mount. The tripod is a tall, strong aluminium Vixen tripod and is seriously solid, yet very light weight. Once set at the right tension the mount moves in altitude or azimuth with the touch of a finger.

It looks good.  Congrats on paying attention to visual aesthetics.

I keep thinking about a FSQ-85. What are they like for visual use? My FC DL rings & TSA ED extender 1.5x are suited to one, so only an OTA is needed.

 

That old Takitis has me in its spell..

I use my FSQ85ED visually, exclusively. My LOMO 80mm scopes slightly exceed the FSQ's sheer crystalline contrast; the FSQ exceeds the LOMOs' (f/6 & f/7.5) color nuances. After 3 years comparing, the FSQ is the survivor among my 80s. Add the Q1.5X dedicated Extender and you have a lifetime 85 for anything from Milky Way to galaxies to nebulae to planets to Luna.

Any downside to the FSQ85ED for visual?

I assume it is like a baby NP-101 ... flat field design?

But, a one 60mm can be a good  planetary scope? 

Thanks,

The Takahashi FOA60Q is an excellent planetary telescope.  There are quite a few reviews and comments about this on the web.

None whatsoever. Views are sharp edge-to-edge, and color nuance is is exceptional for the aperture. Flat field quad. f/5.3 and you can add the Tak ED 1.5X Extender to gain an f/8 scope for more magnification. -Phil

My two 80mm class scopes, a Vixen ED 81mm (F7.7) and an Orion 80mm Triplet (F6).

 

The Vixen has been the scope of choice recently, especially for having a quick, early morning view of Mars.

 

The Triplet is outstanding for wide angle views of the Milky Way. A 24mm Panoptic gives 20x and is close to perfect.

Bob,

 

What mount is this?

My Takahashi fc60 has Proven to be an excellent lunar and planetary scope!!
On really good nights, I can use up to 83x/inch on the moon and planets, a trait typical of Takahashi fluorite apo refractors!! 60mm may be considered by many to be small, but this little fc60 is light, easy to deploy, and provides outstanding views!!

Looks like an Orion VersaGo 2.  Here's a vintage C80 on mine:

I ditched the metal legs for a set of 1960s Eagle surveyor wooden ones.

I just realized last night that the Zenithstar can ride on my eq3 quite nicely.,It is very tail heavy but I was able to get it so it balances and it moves really well without shakes from thumping or focusing.,Another brain fart a day late but it's going to work out well I think. waytogo.gif

Does anyone have some experience and/or thoughts about the ES 80mm f/6 FCD-100 apo they're happy to share? How does it compare optically with its 80mm 'Essentials' counterpart? I am a visual observer; so AP doesn't apply here. . . at least not yet.

Yet even more beautiful "G & G" set-ups here.

 

  When getting started at this, I cleaned out the sticky "Synta Lube" and regreased the focuser on every Chinese refractor purchased. Afterwards, getting the proper backlash on the gear sets was always difficult.

  Eventually, it dawned on me that this infernal, sticky goo was a clever and functional compromise to keep the price low, as precision machining of a proper rack & pinion gear set is time consuming and expensive. The money saved here, by using the Synta Lube to take up the gear mesh slop, can then be applied elsewhere. Now, I have learned to live with it and to keep my hand and fingers off of it. This may apply some to the mounts as well, I don't know.

 

- mjd

 

I have cleaned and adjusted many Synta focusers.  I often replace the slides with Teflon.  Some come out better than others, probably just variation in initial quality.  But they are always better than before and some come out nearly perfect.

 

I find the key is adjusting the play and friction of the drawtube before installing the pinion.

The joy of a good, small refractor was also apparent to me Friday evening, as I tried to get my Vixen VMC 260L collimated and cooled down...

Today, I used my Tak FC60 to do a quick look at the sun using my home made solar filter. No spots visible but I was able to take advantage of a sunny day to briefly test the filter and observe our nearest star!!
