Here is a picture of my Triplet. I should have mentioned that if it is a Triplet, you should easily know by how heavy the nose end is on the scope.

it could be the same lens. Barska doesn't provide any details. They mostly manufacture hunting gear. This is a departure for them. From what I could see they manufactured the OTA and focuser in house. There isn't anything else like it. The lens could be the same as the one you have. The color correction and contrast are superb on the 80mm triplet I have. When I shined a laser pointer at the lens, I could see 3 sets of double reflections. I don't know if a cemented lens would show that.

it's a heavy telescope. The tube and dew shield are heavy tubing as well.

I was amazed when viewing on the night of a Full moon with bino-viewers in my scope, the Contrast was stunning.
I had Two Takahashi Apo's and the Chinese Triplet won.
I've just done a laser pointer on mine and I only see one set of double reflections, so I guess that the Barska may very well be air spaced.

Meade has relatively low cost air spaced triplet APOs in their 6000 series. the 80mm is f/7. I wonder if it could be the same lens.

There is a VisionKing 65mm triplet APO (Visionking 65390) available for less than $500 free shipping.

the Barska cost me $377 for the 80mm. I did spend about 150 for a focuser. I had mountings that fit.

I have owned several Barska products, I have never been unhappy with their goods.

!!!! THANKYOU for sharing this. I was just about to mail the focuser to moonlight and pay an extra 100 to have them custom fit a dual speed, now I have many more options! I owe you one.

The barska uses FPL-51 glass, vision king makes a similar scope and the glass comes from ohara after confirming with customer service.

Which base size did you choose from GSO? there is an option for 86mm, 96, and 112mm on ebay.

The 86mm is a perfect fit. The focuser on the Barska unscrews from the main tube and the thread size is identical to the C80ED. You need the c80ed adapter also. The Barska focuser has two threads. One for the rotating collar and the ring behind the rotation collar that screws into the main tube. You have to unscrew the part that goes to the main tube.

Here is another picture with the tube extended. The focuser makes a smaller package. It is 18 inches with the tube and focuser collapsed.

Wow that looks great. Do you think the fine focus is mandatory for astrophotography? I find that i rarely use fine focus on the existing crayford.

I don't do photography but i do use the fine focus at times. I don't think it's absolutely mandatory. it just makes focus easier sometimes.

fantastic, is that a CG5 mount? I just ordered a GSO setup off of ebay so thanks for being the first one on the internet to figure out the focuser on the magnus! This is really going to help people out with this scope, I think the number one reason people return it is because it wont support the weight of a camera or eyepiece/diagonal very well.

It's an older CG-4 mount but i think it's equivalent to the newer CG-5. I was scratching my head as to how to adapt the GSO Crayford and while playing with the Barsa focuser the part that screws on to the main tube came loose. i had the C80ED adapter and amazingly it fit. It does shorten the tube so you may need extension tube for certain eyepieces.

Well jrbarnett - you just cost me $369. I was planning to get one of the 80mm Orion short tube refractors I've been seeing for about $100, but now I have a C80ED on the way and it should arrive on Tuesday. Oh, since I was going to spend $100 anyway I guess you only cost me $269! Now to find a mount worthy of it.
