  1. I captured these images on the evening of 02/21/2021 and the early morning hours of 02/22/2021.All three asteroids are currently in the constellation Leo, making them easy to image on the same evening.Asteroid (4) Vesta is currently at magnitude 5.9Asteroid (29) Amphitrite is currently at magnitude 9.1Asteroid (113) Amalthea is currently at magnitude 11.05
  2. Here's another entry in the satellite challenge for you folks to judge. This is part of a very long live virtual star party I was doing for a few people but I actually had this planned out. I had never seen the top secret U.S. Department of Defense X-37B unmanned shuttle before and noticed it was going to make a pass this evening. I've linked to just the part of the video where I begin talking about the satellite a few minutes before the pass. If you care to jump straight to the satellite pass, there's a table of contents in the video description that will get you to about 10 seconds before t
  3. I posted this in another area and a couple people mentioned that I should enter it here. I've never considered an asteroid a satellite but using NASA's very broad definition, just about anything can be considered a satellite. So here's my entry of an animation I created a couple days ago of the asteroid (4) Vesta in the constellation Leo.
  4. One hour each - LRGB60x 60sec = L12x 5min = RGBExplore Scientific ED127mm w 0.7x reducer/flattener = 652mm fl. f5.25ZWO ASI1600mm, Baader LRGB filtersProcessed with APP.
  5. We had a great night out last night and I managed to gather more data for my Thor's Helmet project as well as some time on the Leo Triplet. In between filter changes on the Leo Triplet, I decided to make this animation video of (4) Vesta since it was close by.Just a bit of info on (4) Vista, It is the second-largest asteroid, containing an estimated 9% of the mass of the entire asteroid belt between Mars and Jupiter.It was discovered in 1807 by Heinrich Olbers and was the 4th asteroid to be discovered which is the purpose of the (4) designation. The first three were Ceres, Pallas, and Juno.It
  6. I re-processed the same data to work on the star colors. There were too many green stars in my first version. Hopefully this is improved.
  7. Ah, sorry, forgot to leave the major details. 15x 60sec subs on each LRGB 40x 5min subs on Ha = 200minutes. 13x 5min subs on OIII. I was hoping to get 200 minutes of OIII data but it made it down to 20° altitude so I had to quit for the evening. I'm a bit of a faker when it comes to post processing. I don't have PixInsight so I use Astro Pixel Processor and PhotoshopCC. I processed the LRGB image to get the star colors and then I processed the narrowband in HOO palette. Into PS and I selected stars only on the LRGB image and copied them on top of the stars in the
  8. Explore Scientific ED127mm refractor with .7x reducer/corrector = 652mm f5.25ASI ZWO1600mm camera - Gain 139: Offset 10: cooling to -10°CGX MountNINA capture software handled everything like a champ, framing, guiding, auto-focusing, Meridian flipProcessed in Astro Pixel Processor and PhotoShopCC.
  9. Share your results here so we can compare.
  10. These are four frames I captured a couple of nights ago while doing a YouTube live stream. Imagine my excitement when it happened while I was talking to a few friends that were watching. You can watch the entire 3 hours here: https://youtu.be/NN55BevCzj8 or jump to 01:21:20 for the lunar transit. I'm right under the flight path for the jets coming into McCarran airport.
  11. This is a LiveStack direct from SharpCapPro with no additional editing. Explore Scientific ED127mm APO with a 0.7 reducer/corrector giving a focal length of approx 672mm @ f5.25, Baader 7nm Ha filter, Bortle 8 skies. My first two exposures were 3 minutes each and then I realized I could go a little deeper so I switched over to 5-minute exposures After 96 minutes, this is how it turned out. No additional processing or cropping which is why you see the black border from where PHD2 was dithering between exposures.
  12. Out with my best friend's two boys to watch the conjunction. No camera's on the telescope, we just watched it up close with our eyeballs. Nice seeing the conjunction at 200x through the Meade 12" SCT. The two boys will hopefully be lucky enough to see it happen the next time around in 2080.
  13. The Bubble Nebula and Open Cluster M52 in the constellation Cassiopeia. Taken last night (12-05-2020) from the Lake Mead National Recreation area east of Las Vegas. Explore Scientific ED127mm APO, ZWO ASI1600mm camera, CGX Mount, Baader Filters, acquired using NINA software. 20 minutes ea LRGB, 90 minutes of Ha and OIII and only 9 minutes of SII because clouds rolled in on me. Processed in Astro Pixel Processor.
  14. I decided to image the sun today and it seemed a bit hazy so I wasn't planning on sharing anything but then this happened. https://youtu.be/Src6v4nxv5s
