    Grant has today built an addition to our inventory system that automates this process so it now updates - automatically - multiple times every day 🙂 

    Would you be kind enough to ask Grant on my behalf could he also generate a 100% discount token linked to my FLO credentials. That would help me greatly. Thanks Grant in advance.

    The oft-used artificial star is just a ballbearing illuminated from a little off axis so you don't see the source. Only the bit of the ball nearest the telescope reflects light down it, making it an excellent approximation of a point source. You'll find this system in professional optical shops.

    Similar to what Es Reid uses.

  3. Thank you for this thread. You have helped me to make up my mind about my Atik 428EX Mono camera. I will keep it alongside my ASI 1600mm Pro.

    I was currently going to sell it. But seeing this thread reassures me CCD is not dead by any means. 

    What I like about CCD, very little noise and longer subs without amp glow with good set point cooling, without taking darks.

    Thank you.

    I cannot see the point. My secondary rarely goes out of alignment and it is no bother to use an Allen key to tweak if necessary.

    I agree, my secondary hardly goes out of alignment on my newtonians, however I can see the point of them on the primary mirror side as that is the side you would need to collimate more often if you don't have collimation knobs.

    I think Bob's Knobs are a good product, I believe they were initially made for schmidt owners instead of using Allen keys for collimation, a much better solution, the last thing you want is to scratch your corrector plate in the dark with an Allen key.😪

    Hi everyone

    After having had only a dim 72ed for the past weeks, it was nice to get something bright and lively once more.

    Here are some clusters: ngc884 and ngc869 in Perseus. ngc1907 and m38 in Auriga.

    Thanks for looking.

    Nice processing, when zoomed in the brighter star shapes look triangle.
