Russia came thru... 80mm f/8 nicknamed "Kiev 3" for it's first postal update arrived. Box was travel worn, but the seller did a good job anticipating and the scope survived.
It's heavy; don't have a weight yet, but it is heavy. Glass is quite quite good. Focuser is firm and slip free aannddd not 0.965". Not "within tolerances" bs close. Have to find the good calipers but it's around 28mm - 0.965 diags / eps just flop around. I borrowed the SkyChief Jrs diag in the end, applied 5 layers of blue tape to the barrel and still had to shim to remove the slop. Oh well. It is centered & tight. I have a number of ~80mm focusers avail if needed - but the current config works. I'll dig out one of the nice diags Em sold me a while back and upsize it or something.
OTA is 96.5mm diameter - it is currently sitting in a set of guide/finder rings on a vixen rail and it seems happy enough. The finder peepsights are not installed yet. I'll do those and a synta finder bracket shortly - there are a couple extra holes on the tube. Somewhere, I do have proper rings.
Removed finger smudge from center of objective with optical wipe. No clams or coating degradation. The tube is thick and heavy - repurposed electrical conduit would not surprise me.
I have smoke haze (I guess), clouds, the moon, Mars, ver few stars. I did manage a couple faint - ghostly faint - star tests. 20mm & barely discernable, but discernable 6 & 5mm. AD/rings look(s) good - no comets, no skews, etc. Concentric and as clean as tonights skies allow.
5mm is the current limit with the SC Jr diag. Focus + ~1/4 turn in. A focuser replacement is in order, given the non-standard kinda 0.965 vb - which, btw, is very, very well made.
Lunar @ 6mm, CA is low on the limb - a fine highlight, unnoticeable along the terminator. Skies probably help in that respect. Plenty of detail.
Mars - Any detail @ 6mm is blurred @ 5mm. (~106x/128x). As expected, not a big nor bright image - but, +/- skies, clear & fair sharp. Really need a good night and proper star, test, but I am not unhappy at the moment. Better glass than I knowledgelessly expected.
$250 / $340 shpd. It's a Russian scope, it's an 80mm, f/8. I have longer & shorter 80s, but no Russians, so I found that enticing - how would one measure up? So, for me the price was okay = it was worth it. It's good I have a number of 80mm focuser 'upgrade' options - maybe get 10mm more 'in', maybe go 1.25 or larger - depends what fits, what works. I don't think this was designed with diagonals in mind. It isn't a Cadillac, but it isn't a Skoda either - it is "Kiev 3"!
Peace and Good Skies...
p.s. the long bolts came with the rings and are tipped, but ugly, yes. It's also undermounted.
