Appreciate any thoughts/comments about the scope too. I know it was a competitor to Tak's FSQ106 - which it lost out to - and that it was pretty limited production (how many??)
Thanks in advance.

When they were introduced, being a long-time Vixen fan, I was pretty excited as I thought they were quite a good looking scope but I never had a chance to get a hold of one.

It's a 4 element Petzval-Nagler astrograph (very similar to the TV101 optically). 4" focuser. f/5
HEre are a few pictures of the one I bought, and the ONLY advertising shots I can find of one.
According to one well known German company (), the DED108SS is SUPERIOR to the Tak FSQ106. Why it did not succeed is anyone's guess.

I have "settled" with a Vixen FL102S and this DED108SS, with a GPD2 mount, and an SXW (with NexW board) mount.
Vixen maintains Japanese quality at a reasonable price. I prefer of course the truly Japanese made examples, unlike the newer Synta subcontracted stuff.

fwiw I've been looking for info/acquiring an A100SS(?), a 4" f/5 achro big brother to the A80SS (made in Japan glass). I thot I'd seen it announced a couple of year back ...

It's moderately heavy at 6kg, but there's a lot of glass - 4 elements in total (Petzval-Nagler design). Tube is hefty, focuser is incredible! There are 2 focuser tensioner screws - one seemingly moderates the rearward travel friction, one the forward. It'll hold a LOT of weight (seeing these were made to hold the old 6x7 film cameras). Never going to need to even think of changing this focuser (not that I could!),as it is pure silk (but I have always liked the old Vixen R&P's). The knobs are Takahashi-esque silver anodised aluminium, though solid.
I took a deep breath, removed the sliding dew shield, and partially unscrewed the 6 locking screws from the objective cell. I marked the factory position, then unscrewed it to remove the almost not visible mold spore. I did this (after carefully blowing on the lens) with 6% hydrogen peroxide to kill and remove the fungal spores (which is what we do in micro labs to remove fungi). Repolished with a fresh lens cloth, and reassembled. WOW.
Baffling is EXTREMELLY good, and it does appear flocked, not just painted.
Of course, tonight has turned cloudy Down Here Down Under, so no first light tonight. Will try here out visually tomorrow on my favourite tree to line things up.
So far, without looking through it, I am utterly impressed.

Congrats on a great and very rare scope. One of the ultimate 4" refractors for sure!

I won't bore with details, but it was mind-blowingly spell-bindingly brilliant! Better than the Taks I have looked through. INCREDIBLE contrast, INCREDIBLE colours (no fringing, of course ).
Wow. Imaging tonight

It will be CCD when I finally get one done.

My SXVR-M25C went back to SX for repair, so I used my OLD SBIG ST-8XE mono with CFW-8 filter wheel. I exposed H-a only.
Shown below is a SINGLE 200 second H-a exposure on B33. NO flats or bias frames, and only MaxIM sequence generated auto darks applied to each image. Binned 2x2.
Needless to say, I think this scope and I will have a very long and happy relationship together. My Sharpsky autofocus system arrived 2 days ago (after this image was taken), so I should be able to nail it (the pinpoint focus on this, being an f/5 scope, is EXCEPTIONALLY small - microns of movement!)
