Portability can be defined many ways. I once had a 600lb 20-inch telescope that took an hour to assemble/disassemble, two cars to move and three people to set...
... In that case, you need to get a copy of newtwin.exe (it's free) to help design your scope. John has already mentioned that a 10" ID is too small. Newtwin...
Thank you to those of you who have been encouraging. Though I realise mine is the measliest of projects, I'm flummoxed as to why a lot of you seem to be...
... I think what's really happening is we're trying to slow you down. When you mentioned using wheels for az, and a 10" ID tube for a scope with a 10" mirror,...
... I think you've gotten the wrong impression and your nose is now out of joint. I've followed this post (and offered several responses) and non of the...
Stick to your guns. There's absolutely no reason that a scope can't look great and function great as well. Aesthetics don't effect the view at the EP and...
Dive in and learn from your own mistakes if you must. Your optics can travel from scope 1 to the final product. It's just materials and time. I'm very familiar...
Not to worry...I'm not building it for quite a while yet...I think maybe my enthusiasm made you think I was gung ho & full speed ahead on this immediately. I...
Good luck building your scope! I kind of cheated when I made my first, a truss Dob. I bought a commercially made Hardin 12" Dob and used it for a while to see...
Hello Bruce, I went to your album and looked at each photograph. I admire your telescope construction and ideas that you incorporated into your telescope. I...
Hi Charlie, I'm also a ham since 1975. It is rather amazing what can be done with a scroll saw and a table top drill press, but then I've been working with...
HI, I just acquired a 2" and 1.25" H-beta filter. Besides the Horsehead and California nebulae, are there other targets that an H-beta is good for? Thanks, ...
Jim, I wound up going a slightly more expensive route. I bought 3/16-24 SS threaded rod and three SS Knurled-Rim Knobs with a 3/8" set screw (McMaster...
Hey big dobers. Just uploaded some LD (low definition) Video of my install and operation of the Servocat drive system on YouTube. I am compiling some HD right...
There is a non-contact pocket thermometer (infrared) for sale at Harbor Freight Tools this week. Price is $12.99, shpping extra. Reads to 1/10th degree C or...
I am ready to upgrade my focuser on my 12.5 dob and I am interested in your opinion as to whether or not the Starlight Feathertouch Focuser is still the best...
Be careful with these infrared thermometers and check the instructions. Most of these instruments are calibrated to read accurately only for materials with an...
One other thing: read the instructions and you will likely find the accuracy of this instrument to be no better than +/- 2%, maybe worse. And, factoring in...
-Hi there. You may also want to consider the Clement focuser, at www.clementfocuser.com as well as the Moonlite focuser, seen at www.focuser.com/index.php . I...
Since the front of the mirror is not only poorly emissive, but also highly reflective, the temperature measured will be governed by whatever is reflected in...
I had bought a feather touch 2020 for my 10" Dob, and then just recently I bought an 18" Dob with a Moonlite CR2. The Moonlite is nice, but I find my feather...
Nils, Excellent point about the mirror temp being measured on the reflective side. I had forgotten about that. And yes, I am referring to temperature units of...
