Doesn't happen, in my experience, with well baffled refractors. Probably because refractors have so much less tube currents to start with. I have seen effects of the tube baffle in star tests of schmit-cassegrains. I have not looked through any properly baffled newtonians.
Yeah, learned recently that even though it might look clear, a sky might not be. Most my raw captures since I started look similar. PP and high framerate capture helps, but im really looking forward to that real clear sky.
Instead of the so called, variable nebula as they call it, what if NGC-2261 is the theoretical (white hole) or perhaps a dimensional portal through which bright light is backlighting interstellar gases and dust!? Could be the purpose for James Webb and the reason for disclosure recently.
Tycho (85 km Now go to google earth draw a line 85 km long then zoom out as far as it let's you go (63km) You can't see the line from 63km They say the moon is 384 400 km away How can we see it if it's that far?🧐
Excellent presentation, I would have liked to hear more if more time was available. The Saturn example hit home for me. We lived in San Francisco when I was a little kid and one night a neighbor set up his telescope on the sidewalk and allowed anyone to look through the eyepiece. I remember being excited about having that opportunity, I had never looked through a telescope or binoculars before. I was about six years old at the time and when I did have a chance to look, I immediately recognized the object as the planet Saturn because of the obvious rings surrounding it. I also recognized the telescope as a refractor, I didn't know it at the time, but later in life when I became more interested in astronomy, I knew it wasn't anything but a refractor. I believe that event and also as a young city kid going on a camping trip to the Sierra Nevada mountains, whereupon I was marveled by my first view of the Milky Way and the massive number of visible stars that these two experiences were responsible for my later interest in astronomy.
Thanks for uploading. I had the opportunity to view a rocket launch in 2018. Memorable experience. I shared a pretty fun video of the journey to my page.
Fascinating presentation for a person who has looked upward into Night Skies and wondered how complicated the process is to take the marvelous pictures of our Planets and distant Galaxies.
Those trees look like they could use some cleaner ground water. Is this park being used as runoff for industry nearby? I was going to comment on how hard it is to even make out Scorpius or Sagittarius, with all the other stars so beautiful and bright, but the more I look through those tree branches, the more concerned about their health I become. I'm about seven degrees west and one degree south of Ottawa, our forests here in Michigan have much the same composition as those of this park. Those look like Pinus strobus, eastern white pine, maybe 100 years old, probably suffered a lot growing through the last 50-100 years of industrialization in the Great Lakes region. I have to wonder how long they've been standing there and what ultimately did them in.
Could you share what was used to film, and perhaps edit, this? Camera, lens (or lenses), settings (shutter speed, aperture, ISO, etc.), programs, mount? Any of that sort of info in the description would be wonderful. Thank you, and thank you Eric LeMay and RASC of Ottawa, for sharing this beautiful view.
A very interesting presentation! Thank you for sharing your insights, Dr. Alibay! I’m looking forward to watching the landing of Perseverance live in February.
