  1. Actual webcams no as they don't support longer exposures nor good image quality. There are some cheap entry level dedicated cameras like some QHY/ZWO/Svbony models and that's better used with a lens or very short focal length APO refractor. 8" Newtonian will give a very small field of view (only DSLR for that) plus small pixels of such cams don't help either (quite quickly you will run into guiding problems for 8" telescope - requiring guide setup and way more precise mount setup assuming it can track well). Even if you are getting a DSLR - try imaging with like a 100 mm lens first (all attach
  2. I've made some benchmarks of few popular astro processing apps (Nebulosity, PIPP, Autostakkert) and you can see the results on: https://rk.edu.pl/en/benchmarking-astro-processing-apps/ It turns out some apps do like lower latency of Intel systems while storage speed does matter as you could expect. For some processing NVMe SSD or a Ramdisk is the fastest.
  3. We have Jupiter on the night sky, Moon shows up from time to time as well. Let's try to do some more "exotic" type of imaging of those objects: * Io/Jupiter sulfur torus and sodium clouds that can be photographed with the help of [S II] DS filter or a custom narrowband filter centered around 589nm for sodium. Io or the whole Jupiter in the field of view recommended, lower resolution than when doing normal imaging * Lunar petrographic imaging showcasing surface age and composition. Requires 5 wide bandpass filters, mostly in IR * And as a side note 630 nm "neutral oxygen" filter for so
  4. Tried Jupiter and Saturn this "morning", got to bright for Mars sadly, although imaging low over horizon isn't that promising either. 14" DK, ASI178MM, ProPlanet 742: And a very quick daylight test with a stand-alone microscope camera (HDMI, can record clips): This one was without ADC (tried it with ASI camera but even with nearly max setting some dispersion was still there). The camera has very small pixels and even with downscaling it does it's bit to big but still, could be handy as a stand-alike option (still have to test exposure control as it's auto with s
  5. Like a week ago I've tried to test RedCat51 and ToupTek ATR3-16000-KPA color camera. Strangely enough guide camera could not pick up any guide stars (got defocused somehow or camera playing tricks) so had to go with 30 sec exposures times 190 with Baader Neodynium as LP filter.
  6. Started imaging like a week ago but due to weather or Moon could not finish it, only 20 frames (60s if I recall correctly), Svbony UHC, RedCat 51, ToupTek ATR3-16000 color camera. Full frame: link 2 x bin2: Crop on Hubble's Variable Nebula
  7. Venus show around 17:24 local time through few filters, only UV give any clear details. ASI178MM, 14" DK f/19. 1000nm longpass: Astrodon UVenus: UV-IR,IR,UV (UV as luminance to add contrast.. and noise): bin2:
  8. I've picked up a 60 mm Mak on a sale from Astroshop in like December and managed to do some testing, viewing with it. It's likely just a SkyWatcher rebrand but SW seems to not really offer less than 90mm Maks that often. At 77 EUR the price is very low for a telescope and it works - at low magnification you can see somewhat small but sharp Moon. On the other hand I had to collimate it and had some problems getting the correct defocused star image - and thus good quality of higher magnification views. For daytime use, as a finderscope for a bigger telescope or maybe even a guidescope it co
  9. Looking for Sky Watcher focuser for SCT/Mak - for compatibility with their motofocus. If anyone has a spare one I'm interested
  10. Raw Rosette stack: https://www.dropbox.com/s/07f5uj4azl9z4h7/roz.fit.zip?dl=0 Gradient removed in IRIS:
  11. It's somewhat in a big city, but on the edge and having only some buildings and then forests. I rarely had gradients, few times used IRIS to remove it, but that was with mono and CLS or narrowband filters The local neighborhood street lights are slightly below my balcony and they do glow directly quite a lot. That could be the more direct cause depending on sky region. With H-alpha filter I was able to catch Simeis 147 so the sky can't be that bad
  12. Got a break in the clouds so I've managed to get few more test shots from the new set - RedCat 51,ToupTek ATR3-16000 color camera, Baader Neodynium as the LP filter. 20 x 180s, even it's high in the sky still have some gradient: Rosette nebula was super hard to see. The stars were there but nebulosity became visible only at longer exposures (where as with mono camera and CLS or narrowband filter it was "detectable" even on ~sec exposures): The gradient is strong, I have to remove it as there is way more signal there: It's like one of the stre
  13. I got a new setup ready and only a short opportunity for first tests, but still managed to find out I need a smaller counterweight ToupTek ATR3-16000 is a color cooled camera with same Panasonic sensor as ASI1600 (RisingCam on Aliexpress, also branded by ES, Astroshop and others). Crop, 10s x 200; Baader Neodymium Moon & SkyGlow: Imaging setup (- helical focuser): To have more fine focus on the RedCat 51 I used a very short non-rotating T2-T2 helical focuser from Teleskop Express. More info: https://rk.edu.pl/en/redcat-51-and-touptek-atr3-16000
  14. I got few astrophotography related books and checked what they offer and how modern they are. Books in question are: OpenSource Astrophotography 2.2: Your first low cost astro photo from your backyard; Karl Sarnow Scientific Astrophotography: How Amateurs Can Generate and Use Professional Imaging Data; Gerald R. Hubbell The Astrophotography Manual: A Practical and Scientific Approach to Deep Sky Imaging; Chris Woodhouse Astrophotography; Thierry Legault Review: https://rk.edu.pl/en/quick-review-few-recent-astrophotography-books/
  15. I have few questions about the Panasonic and IMX294 big DS cameras. First of all - is anyone using Touptek/Rising Cam/Altair cameras with those two sensors? How do they perform and is the software/driver side stable? Do they work with FireCapture aside of ASCOM imaging apps? As for mono ASI1600 and alike cameras - do you get any pattern when trying to do a flat frame or lunar/solar imaging at very short exposure with high gain? (like 10-20ms with very high gain and then moving it lower)
