Astro Tech 115 APO ED triplet (engaged impulse drive)
What did it for me really was the fine tuning. I think that all telescopes should come with it.
I also bought the non-Meade Meade 82-degree 14 mm waterproof ocular they had a hundred of at half retail.

Triple lensed fracs are so yummy when looking at planets.

Re: Astro Tech 115 APO ED triplet (engaged impulse drive)
I noticed that right away: there is no neutral position. If the AT-115 does not work, it can sit in its case until I get a tripod and mount.
And I am still waiting for a diagonal and for other gear. I bought a 1x Certified Pre-Owned Explore Scientific 99% Reflective 2" Diagonal marked down to $119.95 and also from Stellarvue one of their 90-degree prisms with a focusser. (The Stellarvue is for my 102 mm.)
But thanks for the heads-up.

Re: Astro Tech 115 APO ED triplet (engaged impulse drive)
I might need to wait another week for clear skies to test it, but I did set it up again in the living room and it seems OK. It is front heavy. But so is my 102 in the First Light mount. As you can see, it is balanced to the back for more moment arm against the weight forward. And I added the foam rubber guards to protect it from falling forward.
I agree that the Twilight mount will serve well for the 102 mm. I tried attaching a grip to the 102 and just took it and the original off and just move the telescope by holding the tube. (It's like riding a horse Roman style plowing with two hands instead of guiding with one hand English style like they teach now.) Anyway, with the
Only thing is, the tripod spreader plate has a huge 2-inch hole. I understand: it takes 2-inch lenses. But I already had something fall through that disposal chute when I was setting it up the first time. It just seems to me that it is better to have a 2-inch attachment on the plate over a 1.25-inch hole than to have a 1.25-inch eyepiece on the ground.
As for the 115-mm

Re: Astro Tech 115 APO ED triplet (engaged impulse drive)
My first telescope was a Celestron
I know the same learning curve from numismatics. I was an editor for Coin World when I finally figured out that I am not a collector. As they say, education is expensive but less expensive than ignorance. Also: Better to regret the purchase you did not make, than the one you did.

Enerdyne website here: https://enerdynet.com/
My review of the store from two years ago: https://necessaryfacts.blogspot.com/201 ... s-bay.html
(My wife's family is from Suttons Bay. In all the years we have been up there visiting she never let me go to the store. She let me go to bars with her cousins because she knew that I would not drink more than one or two... but she never let me go to Enerdyne. The last time, I forget how it happened, but I was alone in a house two blocks from the store. That went OK, actually. I bought something for my telescope and paid cash, pocket money, basically. My mistake was locking the door on the way out. "Why???" Now we're all locked out." Village of 650: why lock the doors?)

Is that Nagler smoothie (aka "original" or type 1) then?mikemarotta wrote: ↑Thu May 20, 2021 12:58 am Now that I have one nicer ocular for the better telescope, I thought that I would see what a really nice one would cost. So, I went to Tele Vue Optics to look over the handiwork of Al Nagler. They do not list prices. But they do list sellers. And I know one of them, Enerdyne in beautiful Suttons Bay, Michigan. So, I called them for prices and availablity. Nagler 31 mm = $666.99; Ethos 21 mm = $854.95... "Ok," I replied not wincing, "How much for a 7 mm?" One ninety nine. (Wow!!) "... only have one... been on the shelf a long time..." So, it's a Model 4?, I asked. "It's older than that. It's from before models." So I bought it.

Re: Astro Tech 115 APO ED triplet (engaged impulse drive)
Dunno. I bought it over the phone. They messaged me a picture of the receipt and UPS shipping label. The receipt only says, TELE NAGLER 7.0
I just did a google search and found the Type 1 7mm "smoothie" discussed on Cloudy Nights and found a couple sold on Astromart. CN reviews were mixed, of course, and reflective of cognitive dissonance. Those who upgraded to later models are happy that they they gpt better coatings and eye relief. Those who kept them say they are great. When it arrives, I will post it here, of course.
(Rain and clouds through next Friday here. Do you think that if I stopped buying astronomy gear, the skies would clear up?)

Re: Astro Tech 115 APO ED triplet (engaged impulse drive)
I had to wait to get the finder scope and then get it mounted. It still is not perfect. As you can see the telescope balances nicely because I bought a diagonal and I am using larger occulars. I also have a non-Meade 14mm 82-degree.
We will see how shaky it is when the monsoon season finally ends. As with my 102, I wrapped some rubber around the tube to minimize the inevitable small shocks from touching the base.
