![]() Yes, once again the commercial product is called HyperStar and the links mentioned above will give you the product details. Has anyone done this or know how it's done? On this Celestron webpage in the "Fastar - Cameras" section, is a picture of a DSLR camera mounted more or less directly to the corrector plate Fastar. It's not for everybody, but I love It! See below and Įdited by Noah4x4, 23 April 2020 - 04:27 PM. Visual collimation is preserved, because a tiny screw in the side of the mirror slides into the housing so maintaining its original position. When you remove your secondary mirror, it is cleverly stored in the Hyperstar protective cap. However, if you own an Alt-Az it's cheaper than replacing it with GEM and autoguider etc. Cost is however an issue as Hyperstar is an expensive device, but it is cheaper than RASA. Here, I use a high resolution large sensor camera and a 4K UHD display. A downsize is you then need more camera Zoom. Frankly, it is a bit like "cheating".Īn upside is that removal of your mirror increases FOV x5. ![]() The benefit of extreme short exposures is you don't require polar alignment, nor wedge, nor GEM and no autoguiding. It's hence really good for near live observing. If I use 10 x 6 second stacked exposures (one minute) they will produce a result the equivalent of 25 minutes at f/10. The advantage is it makes your scope especially 'fast' and images at f/2 will form 25x faster than at a scope's native f/10. Hence, it is affixed to the front of the OTA, so no worry about rear end clearance. If your scope is Fastar compatible, you can remove your secondary mirror and replace it with an optical device called Hyperstar to which you fit your camera. Has anyone done this? Is it hard to remove? Dangerous? Collimation anxiety? And if it is so revolutionary, why has it not been advertised widely with the scopes before? Mostly I find it odd that they're advertising something they don't sell anymore, with no suggestions of what to use even. I searched archives, and found nothing terribly recent(although interesting discussion about a Schmidt-Newtonian in February.I wonder if it prompted the email?). If you want to do it, it says to reach out to third-party vendors that sell Fastar or Hyperstar compatible gear. So all you do is remove the mirror.does it just "screw out"? And you drop the webcam in? So I get the Celestron email the other day entitled "Fastar Me"? The opening graphic says "2 focal ratios are better than 1", and says suitable for capturing images from rear or front. If paying with PayPal, add the fee.I have had my 8SE for some time, read Mike Swanson's book cover to cover (II), and I have never heard of Fastar to the best of my recollection. My only reason or selling this setup is that I was fortunate enough to get a used Riccardi-Honders and I don’t need two wide field setups. I can, however bring this to the 2023 NEAIC/NEAF convention in April. ![]() Nonetheless I would MUCH prefer local pickup. Leaf makes cases for touring musical groups so they’re made to take lots of abuse. The Leaf custom case is a thing of beauty. Images with this scope using a 2" L-Extreme Ha/OIII filter (not included) are amazing. The Octopi tilt corrector is really needed at this extremely low f-ratio. I have never had issues with this scope and it takes fantastic images, many of which can be seen on my site on astrobin under user=w4sm. If you’re reasonably polar aligned 5+ minute exposures are beautiful without guiding. ![]() ![]() If you want to get into wide field imaging this is a fantastic setup. Split cover allowing covering with the camera/Octopi installed This is a like-new first generation 11” Celestron RASA, f2.2. ![]()
