awesome, thanks rkelley8493.  I think you are right after checking again:

Micro Pinion Assembly Takahashi Retrofit, 2.5" Diameter Telescope Focusers (fits Takahashi Sky 90, FCL-90 Telescopes, and FC 100)

DZ uses the same focuser as DF & DL, the 2.5".   TSA models need the 2.7".

I guess what confused me is the Tak America page says:

"The FC-100DZ utilizes the same focuser used on the FC-100DF and DL and weighs approximately 3.8 kg."

and the DF page says "The FC-100DF is optically identical to the DC model, but features an enhanced 2.7 –inch focuser"

That's what threw me off as well.. A few Cloudy Nighters informed me about it actually being 2.5", otherwise I wouldn't have known. 

Another curve ball, Starlight lists the 2.7 MPA as being compatible with the FC100, but I think they're referring to the older model (not the DF, DZ, or DC).

Again, thanks all. I need to read back through the thread but does anyone use an electronic focuser? I think in my case if I got the MPA-TAK2.5 it would be this:  https://starlightins...&product_id=475

 

Just curious since these are ASCOM compliant can they be controlled via software for autofocus like with SharpCap while you are imaging? Or is it more like you have to check it every hour or so?

They are. 

 

I also got fouled up with the newer 95mm FC-100 series and thought my 2.7" stuff would work.  It didn't and I had to scrounge around for some Sky 90 fittings and things to make the scope work for me.

 

The lenses are just as good with the new scopes and I guess that's the important thing to remember.

 

Cheers,

 

Ron

All this confusion could be sorted if Takahashi actually updated and modernised their web site. 

 

When buying the extenders, my dealer contacted Tak Europe (also outdated), who in turn had to email contact Tak Japan for the correct model.

My former Tak Mewlon 210.  Yeah, I know it’s not a refractor, but since the topic was about Taks with FeatherTouches...

Scott, would you mind elaborating on how you setup this Feather Touch to your Mu 210 and what model FTF it was? I've been thinking about getting this scope and like the idea of outfitting it with this type of focuser.

 

Thanks!

This was a few years ago, but I believe that I bought the adapter directly from Starlight Instruments (you just have to find the correct one for the scope on their online catalog, as they make adapters for a multitude of different scopes).  I believe it cost somewhere around $75.  You’ll want a FeatherTouch with a short draw tube, but I can’t remember right now whether I used one with a 0.8” draw tube or a 1.5” draw tube.  I bought a used FT focuser from a fellow CN’er, RAKing.  Possibly he remembers and will chime in here.

As Scott noted, get the correct adapter (A20-261 for the 210 ($115 new)) and I'd purchase the 2015BCR ($515 new) for the 210 Mewlon. You  can always keep an eye out for used and save.

Yeah, maybe the adapter was really $115 and not $75, or maybe the price has gone up over the past few years.  But it’s the focuser that’s the really pricey item.  Unless you really want a brand new focuser, or must have it right away, I’d recommend waiting to see if one shows up on the used market, and you’ll likely save a couple hundred bucks.  People list these on AM and CN Classifieds all the time.

I tricked out both my TSA’s with with the 3035 focusers. I managed to get both sets used save for a couple of pieces I got from SL and the was still $1700. About the price of a nice used  4” Tak ED. However Scott’s right I saved about 300 bucks per focuser.

 

I just put a want ad out and I had two responses. The trick is making sure you get the right parts and adapters necessary or it could be an expensive lesson in attention to detail.

 

I bought the scopes used and sold the micro focusers from both so that off set the cost as well. However if and when I do sel these scopes...more likely when the SL focusers are going with each one.

Scott, here's a better image of the focuser on your former FS-128 smile.gif

 

FTF 3035 has been a joy to use and makes this great scope even better. The stock focuser was by no means bad, but I did notice  some image-shift at higher powers and I could never quite adjust it to the smoothness and stability I wanted. FT upgrade was totally worth it for me, especially because I use a heavy Binoviewer for planetary with this scope.

 

 

My former FS-128.  You can just barely see the FTF 3035 3” focuser at the back end.  Sorry I don’t have a better image of the focuser handy.
