  1. 11/28/2021 The Wizard Nebula - NGC7380 14x 10 minute Ha subs Total time: 2hrs 20 minutes Explore Scientific ED152 CF APO TSOptics 1x flattener ZWO ASI 2600mm Pro camera - Gain: 100, Offset 50 Chroma 3nm Ha filter iOptron CEM70EC mount Captured with NINA Beta 0007 Processed with PixInsight 1.8.8-11 I'm headed to a dark sky location tonight about 70 miles north of Vegas and plan to add some color to this subject.
  2. I was out doing a bit of gear testing in the backyard (Bortle 😎 last night and decided to throw this image together. Not bad considering I used no calibration frames and the last frame my subject was only 25° above the horizon right in the light bubble of the Las Vegas strip. 9x 10 min subs - Chroma 3nm Ha Filter 90 minutes total Explore Scientific ED152CF APO, iOptron CEM70EC mount, ZWO2600mmPro camera, Captured using NINA, processed in PixInsight.
  3. Ok, Here's the same data I worked with the other day except I've added an additional 2 hours of 10-minute subs in Ha. Explore Scientific ED152mm CF APO ASI2600mm camera Chroma RGBHa Filters Processed in PixInsight, tweaked in PhotoShop 15x3min of Red & Green - 45min ea. 5x3min of Blue - 15min. 12x10min of Ha 3nm - 2hrs Total Integration = 3hrs 45 min.
  4. Thank you so much. I'm anxious to add the additional Ha data to see what that looks like. The Ha data alone looks spectacular.
  5. M33 the Triangulum Galaxy captured on 11-11&12-2021 Explore Scientific ED152mm CF APO ASI2600mm camera Chroma RGB Filters Processed in PixInsight I hoped to capture 45 minutes of data on all three filters but sadly the cold weather sapped the life from my battery and I only managed to capture 5 exposures on the blue filter. I managed to balance out the colors ok in PixInsight. I also grabbed 2 hours' worth of 10minute Ha files as well but that has not been combined and processed into this image yet. 15x3min of Red & Green - 45min ea. 5x3min of Blue - 15min. Total Integration = 105 minutes Taken from north of Indian Springs, NV Mag. 5.72 01h 33m 50.02s +30° 39′ 36.7″
  6. Excellent first attempt. Way better than my first several goes at Ha imaging.
  7. Another vote for the second version. But also as mentioned, maybe bringing out the gold a bit more would be nice too.
  8. Thanks Mark. At this point, that is beyond my scope of knowledge. I'll get there eventually.
  9. Beautiful. You just barely managed to grab the soap bubble in the frame!
  10. Indeed, but the book is about the women that examined the glass photographic plates. The women were called computers and analyzed the glass plate images and basically did all of the work in hunting for asteroids, supernovae, variables, and figuring out the spectrum for all of the stars.
  11. Spectacular. This would be great with about 90 minutes of Ha data added to it. Congrats Wayne.
  12. Beautiful image Brian. What focal length are you shooting with or is this cropped tightly from a wider fov? On a side note, I recently listened to an audio book called The Glass Universe by Dava Sobel that talks mainly about the women in the late 1800's, early 1900's that did much of the glass plate inspections at the early observatories. It goes into great detail about their work and the work of the Pickering brothers and Harlow Shapley. It's a really interesting read for those interested in the hobby.
