  1. Yeah, I looked at qhy for their cameras. Honestly, the 411 based cmos at 150mp looks like an amazing camera. Binned 2x2 it gives a full well of 320k and a huge sensor. Btw, the 0.7m scopes come in at $200k+, so the cameras are a drop in the ocean to compare. This actually looks very good. 🤔 And yes, that would indeed be barking mad. Seems like you would just waste a whole lot of telescope.
  2. Adding fuel to the fire, what cameras are even available for such a monster? I saw the qhy6060 with an 80mm 10*10 sensor mentioned in the thread, but any other available?
  3. Hmm, I'm actually surprised. I also have my 12" 2.4m RC, but I thought having a much larger scope like that would make more of a difference. Obviously acquisition time "should" be faster, with all the caveats of camera etc, but I really thought a tripple in FL would be bigger. On the flipside, that means a lot of the usual targets are still viable.
  4. Damn, still looks small. I don't know that one, what's the size of it?
  5. Yeah, everyone going for galaxies makes a ton of sense. I have a love for the ARP catalogue, so lots to spend time on there. 🤔
  6. I'm curious what could be good targets for these huge systems if they are used for pretty pictures?
  7. Impressive image! What camera did you use?
  8. Agreed. It's incredible. Over two years since I had my hands on my setup in Spain and it still just runs perfectly.
  9. I've had the scope for a while now, but getting the camera delivered has been a right pita due to a hopeless company I shan't name. Yesterday I finally got it running on a beautiful day and messed about processing it. This is from yesterday, Lunt 152THa with a ZWO ASI 174. Roughly 1000 frames, stacked in Autostakkert and processed in PixInsight and Photoshop.
  10. Had a look. Everything is out of stock, so that would have some long wait. And the faff would remain. I think I'll go the Lunt road. It seems like the easiest way for me to achieve what I want. If it goes pearshaped I can also easier sell it I think. Thanks everyone!
  11. I looked more at the DayStar Quantum. Have to say that looks appealing if I can use it with a large refractor I plan to order. 10 min heating time seems like a very small price to pay compared to the 1-2 hours I usually have to cool my nighttime scope. If I went that route for an f/7 refractor, I would need: 1. DayStar Quantum SE 0.3A 2. Baader E-DRF rejection filter in the right size. 3. Rejection filter holder. 4. Barlow x4 or aperture reducer+barlow Is that correctly understood? While appealing, experience tells me this will be a whole lot of faff... The alternative is a Lunt LS152. Made for purpose and would cost the same as the above.
  12. Thanks, that's a lot to consider. Being completely blind to the pitfalls, I am close to deciding on a second scope for home use, which would be a 140mm or 160mm refractor. Is it possible to get these external etalons in that size?
  13. Yes, it's not for lack of choice. That's almost the problem. What I don't want to do is buy something I want to upgrade in 3 months time, so might as well go for proper gear. Interesting about coronado, I thought they were a premium brand. I'd prefer to get something purpose built instead of modding a different frac. Maybe I'm wrong?
  14. I captured this data in December and life sort of kept me from doing something about it until recently. 13 hours of narrowband in 600s bin2 on my RC12. Ok, here it is without humanoids.
