  1. It's been a couple of months since I was able to do any imaging due to the bad weather. Something had obviously changed since the last time, as I could not get APT to work with the camera. I was getting no plate solving and oval stars! After 2 wasted clear nights, it took an Ascom and camera driver update to solve the problem. I think it was well worth it though! Looking forward to adding some Oiii. 20 x 360s H-alpha, with darks, flats and dark flats. W/O Zenithstar 73, ASI294MM Pro. Thanks for looking.
  2. I've not been able to image the Pleiades due to the clouds, so I thought I'd get some practice in on your version! It's surprising how much nebulosity is hidden in there. As mentioned by others, the ASI294MC Pro works best at unity gain. I always have mine set just above this at 126, which works well for me. Generally I stack with darks, flats and dark flats in ASTAP. For your image, I used SiriL to stretch it and calibrate the colour with Photometric Calibration. Most of the horrible gradient was removed with the Background Extraction function. Starnet++ was used to create a st
  3. Just wondering how you got on with this with the current Moon conditions? I would have used the L-Pro to start with and added some Ha later if it needed it. I don't think HDR will help much with Alnitak. It normally becomes a feature, especially if it has diffraction spikes. Tony.
  4. I'd go for the Williams Optics one to match the scope. I'm using the adjustable Flat 73 with my Zenithstar 73 and the stars are perfect all the way to the edge of the field. Tony.
  5. Here are my 5 from 2020, taken with ASI294MC Pro and 11" SCT. Tony.
  6. Thanks for this. I was just checking where the Cave Nebula actually is and it's not where I thought it was! It's the Lobster Claw that I like the look of. Clear skies! (We hope). Tony.
  7. Thanks Lee! I also think I got part of the Cave Nebula at the bottom of the image, which I'd like to get more of. Just need some clear nights!
  8. I took the H-alpha in November and because of the bad weather, had to wait until January for the Oiii. It was -3C when I finished and the whole observatory was covered in ice! HOO palette, modified to show the blue oxygen regions. I'm also thinking about adding RGB stars at a later stage. 30 x 360s each, H-alpha and Oiii with darks, flats and dark flats. Total exposure time 6 hours. William Optics Zenithstar 73 II, ASI294MM Pro. Thanks for looking! Tony.
  9. I think FLO may have what you're looking for? You'd have to check they're compatible. https://www.firstlightoptics.com/search/for/dovetail spacers/ Tony.
  10. Thanks Mark! I've not even thought about locking the focus as it stays where it's put! I don't have that problem, as I bought it to piggy-back on the SCT and have a small counterweight at the top end of the Celestron tube. Tony.
  11. I took the H-alpha in November as a test of my new scope and camera and have just had the first clear night since then to finally get some Oiii. I was wondering why the subs were a bit noisy and the darks that I took in November weren't working. I discovered that the gain on the ASI294MM Pro was accidently set to 400 instead of 126 unity gain! This hasn't harmed the image and I'm wondering what gain other people use with this camera and narrowband? Modified HOO palette. 30 x 360s each H-alpha and Oiii, with darks, flats and dark flats. Total exposure time 6 hours. Thanks f
  12. Nicely done Glenn! I also have a 6X6 Keter shed observatory, modified from a design on this forum, the "Plastic Pig". Mine has an internal rail system, so when the roof is closed I use the original plastic bolts to secure it. Nothing is visible from outside, so it still looks like a normal shed. It cannot be automated though! Tony.
  13. Thanks Martin, yes I'm very pleased! Should compliment the colour version of the camera perfectly. Looking forward to some completed images. As mentioned by others, the H-Alpha flats were interesting! Tony.
  14. Just did a Google search and found announcements on ZWO's Facebook and Twitter accounts, but no further info. Also been following a big thread on Cloudynights. From what I make out, just bin 2x2 to go back to the original resolution and pixel size. Have a look at https://www.cloudynights.com/topic/726990-zwo-asi-294-mm-pro-first-impressions-and-test-images/page-23 Tony.
  15. The sensor is 43MP and ZWO binned it to get 11MP. The new update unlocks the full resolution of the camera. There should be an option to switch between the two.
