Hello all, I'm not sure if this is OT or not but I would like to make my own off-axis-guider. I have my own CNC machining capabilities. I was wondering if...
I have one or two of those. But they are getting to be a has-been in astrophoto uses. They are difficult to find and focus an adequate guide star for the...
Hi Greg, I appreciate the response. I think that I have two problems one of which is "mirror flop" as my C11 mirror does not have a lock. Also my guide scope...

Good work Norm. The repeatability of readings is precision. Accuracy is another matter. Repeatability is what you need to do this comparison. The fact that you...
Hi Norm, Aren't IR thermometers fun!? I have a lot of fun with mine. Anyway, I have a comment about the cooler reading you are getting near the edge of the...
I have become fixated on reaching thermal equilibrium because of its detrimental effects on the figure. This point of view had become so habitual I did not...
Interesting setup Michael. I have not seen this approach before. You are using hypercool or hyperwarm air to accelerate the mirror's acclimation. No doubt this...
Michael, It would appear that this project has kept you off the streets and out of the bars. Thank you so much for sharing. Love your website. Definitely a...
... True. The project was a year in design and has been four years in construction. I've been using the telescope for about two years while construction has...
Michael, You are an ANIMAL! When I lived in Idaho, I had a neighbor that built an airplane. He fabricated the wings in his living room with glue dripping on ...
I changed the subject of the thread to answer your post: ... Nope, no parts used from a Coulter. Although you might notice in one picture a 13.1 red tube...

Hey everyone. I have acquired some PTFE strips 1/8" thick x 1" wide x 9 ft long. I can cut these into any length you desire. And if you need 3/4" wide, I...
That stuff sure has gotten pricey. Tim, what glues seem to work well in your experience? I have a fair amount of Teflon on hand myself. Guy ... That stuff sure...
It is pricey. Tim is selling it at about $3/foot less than McMaster-Carr. I used epoxy on mine. Al...
