I keep thinking about this scope for a while, but only to use it as a second setup with another setup together, and if i get this scope then i will use it with APS-C sensor camera, but i can't decide which one i should use for which, i mean one setup for RGB only so IMX571 color camera, the other setup is only for either Lum or Ha with mono using 4/3" sensor, but i won't decide on this Askar 71F until i first finish my plan or decision of other multi setup.

AstroShed: Thanks for the review, nice work. I'm intrigued by this scope. For me, the price is really more like 800$ for an f5.6. But that also changes it to no longer be petzval design and puts me back to dealing with back focus spacing. Not a huge deal but it does add a bit of complexity. The upside is the weight, the scope would work on a small mount really easily. Are the images you collected at f7? Did f7 feel slow? Slow also reduces CA so I see that making it beginner friendly. I think for beginners ( a lazy imagers like me) you kind of have to assume osc cameras. So I would like to know more about CA in the scope. Thanks for the review and congrats on the new scope. |

Clayton Ostler:AstroShed: Hello, thanks very much yes the images were at f6.9 the native focal length, as I did not have the reducer at the time of the review. and since I have had it due to one thing or another not used it much the CA is very well controlled on this scope, and it was on par with my Esprit 100 which is also very good, the stars are a bit tighter on my Esprit, but for the difference in price, you would expect the Esprit to be loads better, but not the case at all. Enjoy your new scope if you decide to purchase. |
