Is this the same refractor as the AT80ED f7 ?

Looks, specs and price are very similar to the AT80ED. But hard to say if it is "the" same - only the guys at Astronomics might know for sure. Functionally I would think they are going to be very similar.

Which of your Morpheus EPs work best on the moon with the AT80?

They all work well for me - low or high power. I am a Morpheus fan boy grin.gif as I think these EPs bring out the best in my refractors. But on the moon, with the AT80, I think I particularly like the view with the 9mm and 6.5mm. I am not a big Luna watcher, although I would like to do so more - the moon is available so often...

 There are 2 listed and it appears that the  less expensive  one has a 2 inch crayford focuser , not the 2.5 rack and pinion  ,  you would have too clarify that with TS .  Even the page header comes up as second hand and special offers  .   Lunt offered theirs with the 2in "crayford"  focuser  , nothing inherently wrong with it  IF you want too save a few  euros

I don't need it, but an AT80ED is on the way. Astronomics needs our help in these difficult times.

That thought has preceded ALL of my observing purchases!!!  grin.gif

 

Good on you, Ken!

Any reason this tube couldn’t be shortened on the focuser end to  better accommodate binoviewers? It looks like the focuser slides on the tube as opposed to threading on . Correct?

FedEx delivered today. Here it is sitting on an AZ-GTI on a Manfrotto 475b tripod. I luckily had an extra Vixen finder foot on hand as the scope doesn't come with one. 6x30 RACI mounted. First light will have to wait for some clear skies. Really nice looking.

Love it. Makes my AZ-GTI and Stellarvue M1V much more stable.

Hey Guys,

I just received my AT80ED yesterday, looks like an awesome scope, I had a few minutes between clouds last 

night to view the moon, I couldn't see any false color on the limb, the craters were super sharp !!

I do have a question about the focuser, it's a little notchy feeling in spots especially with the course 

focus knob, will this wear in and smooth out or is there an adjustment I need to make ?

 

Derrell.

Ken:  Now that you’ve had the AT80ED a couple of months, what do you think about it?

I like it. This is my 3rd AstroTech refractor, I also own the 102ED and 60ED. I think they are just incredible values. I just got a 35mm Panoptic so I can't wait to cruise around with that.

I'm trying to locate a finder that will attach to this scope, no luck so far.  What are you folks using?

My SV80 (similar scope) came with an Orion 9x50 RACI. I didn't like the way it looked so I removed it but it worked well. I find don't really need a finder with that scope. If I added one it would be a RDF like the one on my my AT102. What problem are you're having putting a finder on?

I don't know of a shoe that fits and has the screws aligned the same way.  I got a Celestron RDF, which came with three different shoes, but none of them work with this scope.  I don't want to keep buying finders that won't work, so I figured I'd ask here.  I emailed Astronomics, but I think they're pretty busy and haven't had time to reply yet.

 

Maybe I don't even need a finder, as you suggested.  I have a 30mm eyepiece, giving ~19X, and I haven't tried using that as a finder yet.  Since I'm going to be mainly observing the moon and planets, that might be enough...?

My SV80 came with a finder base but I used this on my AT102 - https://www.ebay.com...=item288557bb32

 

I just unscrewed the 2 focuser screws off to the side and used them to secure the base.

Finder, isn't that what the AT80ED is ? grin.gif

 

OK, kidding aside, the fov with a 32mm Plossl is almost 3° and with my 2" 40mm Paragon is almost 5° so an optical 30 or 50mm finder always seemed to me to be not very useful. I admit for a few years (I have a 1st gen AT80ED) I did use a zero power red dot finder but now I don't bother. Ensuring it was always aligned each time out seem to take more time than just swapping eyepieces to find something. Over time a finder on this scope just seemed to be more bother than it was worth.

I use an 8x50 raci on my AT80ED but have removed the crosshairs as even in my 8" dob simply centering the object in the finder is more than enough to quickly locate most any object even at high magnification. Without crosshairs small optical finders are great for conjuntions (still awesome for finding too) and too allow for primary and secondary magnified views of an object, for scopes with very narrow views like maks or scts or other longer focal length scopes crosshairs become critical but on widefield instruments they are really not needed and counterproductive in my opinion. Having the 8x50 without crosshairs on the dob has more advantage than on the 80 of course and I really enjoy working the cleaner view without optical obstruction blocking what might be and often is a very pleasing image in the optical finder even though it is just really a tiny achromat. Dammed crosshairs ;-)

Just to add a data point here.  I've had my AT80ED out a handful times and seeing has been mostly mediocre with a few better nights.  On the calmest I was able to push the little 80mm to just over 200x with my Meade 5.5 UWA and 2x Barlow, and I'm happy to say it held up pretty well (I was viewing Izar and the split and color differences in the two stars were quite apparent though a little messy due to seeing conditions.  There were some calm moments of better clarity).  Mostly I've been using it between 63-124x, so it was nice to see it form a good image without becoming too dim.

My AT80ED was due to arrive Monday but instead was delivered today. It certainly is a nice looking scope and seems solid and well-made.  Hope to have it out for a test run soon.

Probably not a bad idea.  If they perform well, it's a real bargain in my opinion.

 

I ordered an Astro-Tech Voyager 2 altazimuth mount with it.  I assume this would be an appropriate mount, what do you think?

 

https://www.astronom...muth-mount.html

That mount looks like the head can be offset (see the bolt pattern on the bottom part of the arm)?

Yes, it can be tilted back to allow the scope to point at the zenith.
