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...
... long illness. ... Though I had my humble Stellarvue 80/f6 at both Arunah Hill Days and Connecticut Star Party, at both events I had the pleasure of looking...
I never met the man, but read great things about his work and company. Sounds like he wanted everyone to be able to enjoy astronomy, no matter if you were rich...
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...
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, ...
Congratulations Patrick! I have never been near splitting delta Cyg. in my ST80. In fact I have some pretty tough job splitting it in my C80ED @ 160X. A friend...
Thank you Magnus. I have not tried the Plato crater. I also have a C80ED. These are great little refractors! Clear Skies, Patrick ... have some pretty tough...
By now some of you have heard of the sudden increase in brightness of Comet 17P/Holmes. It suddenly jumped from MAG 17 to MAG 2-3. I read about it on the...
After reading news of the comet's sudden increase in brightness in the Nexstar group I setup my Nexstar 8i and got out the 80wa that I use as a spotter for the...
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...
Thanks Rod, That tells me that the ST80 will not mount directly to the EQ2 using rings. A pity because the EQ2 is much more sturdy than the EQ1. -Walt ... ...
Well, it might certainly be possible to rig up an "adapter"...that said, I find the Little Guy is just fine on an EQ-1 (what I've been using my li'l one, one...
I had an Orion ST80 on and EQ1 a few years ago. Maybe I got a bad one but the mount was really poor. The RA and dec. knobs kept coming loose and after only a...
... Walt, As Rod mentioned the rings must be a lot closer as the tube is short. My ring mount has the rings spaced at 3-5/16". As for an adapter I'd suggest a...
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 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...
Regarding eyepieces... You want eyepiece(s) that will give you magnifications up to perhaps 150x at most... probably 100x to 120x should be about what you can...
... Dan answered your question about Eyepieces well but I'll add to it. I suspect your "customer" won't be doing much high power viewing with the 8mm due to...
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...
Never seen anything like this. Is this a genu-wine ST80 from Orion or Skywatcher? Peace, Rod Mollise Author of Choosing and Using a Schmidt Cassegrain...
Yup, genuine Orion ST80 direct from Orion themselves. I'm assuming this must be some sort of production issue. I can't be so unlucky as to have received three...
By the way, best way I can describe this problem is like this: Imagine looking through a window. It hasn't been cleaned in a while, and now has a grayish film...
My comment won't matter much, as you'll see, but I'm curious.. is the grayish film on the rear surface of the second lens in the doublet, or the front surface?...
Hi Dan, It's hard to tell, but the grayish film seems to be on the front surface of the second lens. It may be on the rear, but since I didn't disassemble...
Strange, it seems to me. I'd agree from your description and your previous attempts to clean others that it sounds like a manufacturing problem during the...
... For a case - I use a pluck-foam briefcase style case. Several hardware store chains ave them - lowes, home depot, harbor freight. Holds the st-80, finder,...
... I just checked my wife's original Orion ST-80 and the lenses look fine. It was bought a NorthEast Astro Forum about a year after Orion announced the Short...
Hi, I'm Jon and I just picked up an old Helios ST80 :-) I'm currently getting a pinched view of a poorly collimated scope. I have tried the tips and tricks...
