I'd been hankering after one of these scopes for a while as a replacement for my ST102, purely for use as a wide field, low power sweeper scope, paired with a SW 127 Mak on the other end of my Skytee. Yes, I'd been tempted and befuddled by all of the alternatives available but stuck to my original choice and pressed the button!
After the now expected smooth purchase and delivery experience from FLO and DHL, my scope arrived all boxed in cardboard, containing the aluminum case in which the scope lay cosseted in foam...good stuff! The first thing that struck me was how substantial it was and how beautifully made and finished. I'd only ever bought budget scopes before and this was my first premium scope (well premium to me at least) so I was pleasantly surprised in the jump in quality.
Conditions lately haven't been great so I only managed a few viewing sessions with the new scope alongside the ST102, just to (hopefully as I'd paid out 800 quid) see the differences between the two. I need not have worried as the SM was noticeably clearer and sharper, and an altogether more satisfying instrument to use.
As ever, FLO sent the obligatory clouds so that has limited use so far and we are now here just saying goodbye to Hurricane Fiona but I can't blame that on FLO!
My only annoyance with the scope was a self inflicted one as I declined to purchase the bundled vixen mounting bar with it. as I'd already purchased a nice red Askar Losmandy plate whilst in the US recently.. In my naivety I'd assumed that a universal plate would fit the SM but no such luck! The Askar plate had drillings at 88mm centre not 80mm, as the SM drillings on the tube rings. I guess I'll have to wait until FLO get stocks in again for the StellaLyra Losmandy plate with the correct spacings!
All in all, Im very happy with my purchase and am sure I'll get a lot of use and enjoyment out of it, which is the important thing.
