I recognize those red USB cables. get rid of that zwo stock cable lol. I had camera disconnect issues too using those! I use cable matter cables, zero problems in months.. sample size of one, of course, but still!
that discord sound in the background is driving me nuts Jokes aside... this is the future for us amateurs. Its not the same but I'm thinking of getting a second esprit 100 in the future and run it at f3.6 in addition to my already existing one that runs on f4.1 I have so much stuff planned and only a few hours per night!
Hey Bray, thats a very beautiful setup. I love the idea of combining multiple scopes. I am also working on my own with 400mm F2.8 just like the Dragonfly Telephoto Array. I understand that that you preferred the 8" over the 11" due to cost, the difference in price is huge. But i have some trouble with your explanations in terms of speed, F1.17, FOV etc (some of mentioned in the video, some in the comments). Let me explain. 1. with the central obstruction the Rasa 8" is a F2.22 2. with the crop factor of the 2600MM the F number becomes F3.4, because you are only using 43% of the light 3. a takahashi with F3 and a 6200MM will actually gather more light. dont let you get fooled by the sheer opening. it also depends on how much light is actually used at the end of the imaging train 4. the comparison Rasa8+APSC vs. Rasa11+Fullframe is actually very interessting because the resulting FOV is nearly identical 5. the Rasa11 has a true F-ratio of F2.43 with the power of fullframe 6. the SNR on the Rasa8 may be still slightly better, because the FOV is spread on 6248 pixels wide, whereas the Rasa11 FOV is spread to 9576 pixels. 7. the worse SNR of the Rasa11 is invested in a much better detailed image due to higher focal lenght + more pixels. 8. with the 2600MM on Bin2 mode and 6200MM on Bin3 this aspect gets equalized and the Rasa11 image will have insanely better SNR. 9. those points may have lead the Dragonfly Telephoto Array Team to choose the 400mm lens with supporting fullframe. it is very effective in terms of speed, cost, weight and size. I would love to hear your thoughts on my calculations.
Hahaha the star front discord alerts going off in the background Gotta get them tickets open!! Awesome setup , now you can add one more rasa per year and go super deep There is a guy on RU-vid with a 3 rasa 11 setup that has some really cool 3d printed parts he made not sure his username but I’m sure you’ll find him if you look
If you're looking for a test object that might solve an astronomy mystery, I think the origin of the Flying Dragon Nebula is still unknown. It's apparently a supernova remnant, but it's unconfirmed.
this is awesome. dare i call it optical interferometry? also. have you thought about everyone there aiming at the same object and stacking that multi scopes multiple nights? that image would be way more light than any single scopes
Really interesting setup and target plan - wish you all the best. I love the premise behind the Trident mount - so great to see one in action. I also appreciate you sharing what subs you are using and what control programs and how you distinguish which ZWO camera and focuser is which - always a pain when you have 2-3 identical ZWO cameras! Keen to know what sort of CPU set up you use to run WBPP with that much data - do you run bare metal or host a massive VM in the could? Did you go for a big multi-core gaming rig or an old one, two or four CPU Xeon server beast to try and get up to 100 cores to run the threads? Extremely interested to see what you discover! Best wishes!
10:15 You can actually adjust the telescopes that they actually DON'T point exactly to the same spot on the night sky, but with an offset of about 15-30 pixels from each other. Hardware dither lol.
Marvelous Bray!!! What is your consideration on not using multiple instances of SGP? Works like a charm for me while I grab A3 with two piggybacks riding on a RASA8. Dan
That's really cool, now you just need to add a fourth on top for real colour! Why don't you use a single filter on each to avoid having to change them? You'd be collecting the same overall data just in a different order.
I want the full light collecting capability to be focused on one bandpass at once to achieve the speed desired, so it required getting all of the filter sets
Dude I was going nuts during the video, took me a while to figure out that the discord notification sounds came from your video... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-sqELPQxD_IA.html
Three osc one with a ha oii one with sii oii and one uv/ir cut would remove need to swap filters. For people wanting to try this remotely. Unlikely to be as good
Man you don't invest this sort of money to shoot behind a bayer pattern.. you don't want to be running on 25% of your pixels looking for low surface brightness OIII signal
