Hi Heinz, ... I agree it's something of a special purpose telescope, since of course the diffraction-limited field of view of an f/12 Dall-Kirkham design with...
Hi Morris, the easiest solution depends on what software you are using to guide with, does it support the ASCOM pulse guide and the Shoestring guide adaptor? ...
Hello Iver. I have a choice I suppose. I have the following in no specific order of preference: PHD MaximDL GuideDog I will likely be powering the mount with...
Hi Morris,PHD and MaximDL are ASCOM compatible I'm not sure about Guidedog, why don't you install the ASCOM platform and Chuck's Temma driver and give them a...
Iver, Thank you. I will track down both the Temma driver and POTH and see how I go. I am so new to the mount that I have not yet attempted anything other than...
I've spent a couple of frustrating nights working on the collimation on my new Mewlon 210. I also am having problems getting the in focus and out focus images...
Hi Michelle, Hang in there. Collimation really does have to be bang on the money with a Mewlon or the image degrades quickly. A Dall-Kirkham Cassegrain is way...
Hi all, Not to detract from Michelle's response but does anybody have any comments regarding my original posting of : a) why my in and out focus collimation...
Hi Greg, Only just read this thread. I own a Mewlon 300 and live in the UK. A couple of years ago at a specific request I resonded to a forum in the UK on...
Please contact us and speak to Fred. He can help you. Art Ciampi ... From: Michelle Stone To: UncensoredTakGroup@yahoogroups.com Sent: Tuesday, January 01,...
Michelle, SOME of your issues may well be seeing related. As for tight collimation screws, I think that they ALL ship that way from TNR. My M300 came like...
... comments regarding ... ignore the out focus ... Jim, I'm thinking that it is very important that we get our scopes collimated so that in and out of focus...
Hi Jim, Definitely you should contact TNR! But... here's a speculation. If your pinhole is 75ft away then you are shifting the infinity focus point of the...
Hi, I have a Mewlon 250 and must admit have not had come across problem before (although I must admit I had a lot of "fun" collimating the telescope especially...
Jim, Researching a little, it appears that possibly the centering of the secondary could be causing your problem. I never experienced this, but apparently, if...
Hello all, This will be my first post here on this forum as I am fairly new to the Takahashi family. I have several questions. First, I am currently using my...
Hi all, I somehow managed to get my Tak FSQ106's multi adapter ring and a Feldstein 4 adapter stuck together. Nothing I can do will get them apart. I hgave no...
I would like to hear the specifics about how to center the secondary. If anybody knows the procedure or talks to Fred, it would be nice if you could describe...

Taylor, I use strap wrenches similar to this one: http://www.amazon.com/American-Science-Surplus-STRAP- WRENCH/dp/B0001CUMX2 I believe I bought an inexpensive...
Taylor, I have imaged with my FSQ-106N and an Extender-Q in the past. The sections of the Ext-Q have male t-threads, and the ST-series camera D-block (or CFW-8...
There's been several threads about this problem. You are seeing either metal expansion/contraction or aluminum galling. Or both. In the future if you...
Jim, I'm with Bill on this. I would REALLY like to hear what Fred has to say about "centering" the secondary. I've never seen an "how-to" for this, but ...
If you are defocused so far that you are seeing a "donut hole" you have gone well beyond the range for a good star test for collimation. Likewise if you are...
Without a doubt, Gene is correct with his ring concentricity explanation as an overly defocused star tells us very little about anything, but I would like to...
On my M300, took baffle tube off of secondary housing and got a set of calipers and adjusted from the edge of the mirror to the edge of the tube. Took several...
