I ordered an ST80 for use as a guide scope and for birdwatching, but it is back-ordered until the 27th of Feb.. Anyone know if there is a story behind this?...
There is a bit of play on my ST80's focusser tube. I am fairly sure that there may have been a shim put in to stabilise it, but probably the glue holding it...
... Hi Gene, Sorry for the slow response, been away from my scope for a few days and unable to make the measurements. The focuser travel of my old Celestron...
I bought a very cheap (Chinese) 80mm scope to use as a guide scope. The lenses are dirty, but the objective cell is glued on and will require a painful...

I'm on my 3rd ST80, after the previous two had terrible QC issues. This one fortunately star tests very well. It did have a very bad case of astigmatism due...
I picked up an Orion ST-80T on eBay yesterday. It came with an Orion Paragon HD-F2 tripod. No finder, diagonal, or EP's. I'll have to pick those up. I would...
Hi group - I just posted a video on YouTube of the comet: http://www.youtube.com/watch?v=ZpUf19AbJH8 I recorded it thru a Celestron 80f5, using a security...
I have an Orion EQ2 mount and I want to purchase the ST80 OTA from Orion. They sell it with the EQ1 as a combo but I obviously don't need the EQ1. My question...

Hi all, I have a fairly detail review of how the ST80-A can perform after being optimized. The review is at Astromart if anyone is interested. Clear Skies, ...
Hi group, I have been attempting to find out if the Orion Express 80 and William Optics Megrez SD 80 use the same glass in their objectives. If anyone knows...
Thomas Back, the talented optical designer responsible for TMB apochromatic refractors and TMB eyepieces, has passed away after a long illness. I met Tom years...
Hi all, Has anyone here done a side-by-side comparison between the older Orion ST-80's, and the newer ones with the "fully multi-coated optics."? If so,...
... With the pretty much "standard" 25mm supplied with most of these telescopes, you'll get 80x with a 5x barlow. 62.5x with a 32mm. A 2x or 3x barlow might...
