    Default 1st light with Long Perng 110mm f6 APO .



    Well I managed a few hours last night with my new ( to me ) LP 110mm f6 APO , the night was average at best with a high haze covering the sky that caused a bit of wash-out at higher powers 150 - 200x . I tested this with my little 60mm LP triplet that I grabbed out about 1/2 way through the night and it showed the same hazy views , no matter we cant have perfect night all the time .

    On with the review .

    First thing I noticed was that at f6 the sweet spot of best focus is very small , I am used to f10 scopes , my 102 refractor and C9.25 but I got it sorted after a bit .
    On the focus it was basically colour free at the best but only a gnat's hair either side showed red on the outside and yellow on the inside but we dont do any viewing there and as said at the point of best focus it was basically CA free , I was suprised at this being a FPL51 doublet , LP have done a good job here .

    I managed up to 220 on Jupiter and Saturn using my 3mm TV Radian and the view was really nice apart from the light scatter around these bright planets due to the high thin clouds showing plenty of detail on Jupiter that was better than the 102mm f10 achro and the achro is no slouch . On that the CA of the ED 110 was almost non-existant once best focus was found but the red/yellow was only a touch away every time and I am sure I will get better at finding and keeping best focus .
    Mars was nice and crisp but getting smaller and the seeing did not really bother the view like it did for Jupiter and Saturn ? who knows why ? .

    On to deep sky , M22 at 82x and 132x using my 5mm and 8mm TV Radians was nice but the high cloud washed away me seeing intervidual stars , I am sure it would resolve M22 on a better night as my 102mm does this quite easily .
    The southern milkyway's show pieces were nice using my 19mm Panoptic and 20mm Nagler and the high cloud did not seem to intrude as bad at these lower powers ( 34x and 33x ) .

    For a lark I put my 1kg 82*Celestron Axiom 32mm in and at 20x the view was beautiful a huge expance of stars , clusters etc , just awesome ! , cant wait for a better night and just cruize around getting lost in space , it'l be nice .

    I will report back when the moon is back in a couple of weeks and enjoy the few photos . You can see the annoying high clouds reflected in the lens photo .

    Very nice! Congrats on the first light! It's definitely a very nice looking scope. Is that a complete carbon fiber tube and shield?

    Yes . solid CF and it looks awesome in the flesh .
    The focuser is really sweet a lot like the GSO ' Linear Bearing ' on my 102mm f10 achromat but much heavier and nicer finish , I especially like the way the whole focuser rotates 360* and also just the end where the 2 inch diagonal fits , just loosen a knob and the end rotates smoothly and with zero movement , very nice feature .

    Thanks guys , yes its a very well made piece of gear for not much money and I am sure it will see me right for many years , ( also cant really spend any more on astronomy ) as its small , light with very good mechanics and optics and if I need higher powers I have my sweet C9.25 XLT ( also CF ) .

    Also it sits beautifully on the Vixen SP mount , like they were made for each other .

    Cant wait for the moon as I bet this scope will perform very well here , as said a report to come .

    Brian.

    One could order them from Teleskop Express in Germany. I've ordered Russian optics from them happily. Another member here in the US ordered a largish apo and is happy. So depending on your risk tolerance, it's not impossible.
