In lieu of the Cody temple here is a view that I took of comet Atlas the people of the community won't see in its glory.

Wow!

You must have a good mount.

I once taught an intro astrophysics course, but I was learning almost as much as the students, and it was only an intro. It’s not my field.

Do you know why the comet seems to have an inner and an outer tail?

How big is this thing? How far away is it?

That is an amazing photo!

I have a Skywatcher Eq6r. But my scope was bought in 1981. An 8"f6 Newtonian. Optics back then were superior. Comet tails vary from comet to comet dependent on orbit and elements present. The current comet now C/2025 R3 Panstarrs has a bizarre tail. I shot it this week. Here is a shot. Notice the twisted multiple tails. https://imgur.com/a/xWiMZGA

Edit. Atlas is long gone. Panstarrs just left perihelion. Panstarrs has a tail length covering 2 degrees. That is about 6 full moon lengths.

That's a nice shot.

Very nice.

Yes, very cool Rivendale, thank you.

I love these types of images. I love to read about astronomy and ask simple questions or read simple articles about it in an explain-it-like-I’m-5 way. I have always wanted to dive into a little astrophotography. I recently bought a Canon R100 because you can keep the aperture open. I paid that off and I’m looking at the iOptron SkyGuider Pro EQ Camera Mount. I get all my stuff through B&H Photo in New York City which has a lot of gear at great prices. I believe this is the gear that I need to keep the stars from streaking.

I love our local deserts in Southern Cal and can ride a small dirt bike with a backpack and a sleeping bag into the horizon at night learn the craft slowly. One thing I just learned about was burst shots, 10 to 30 seconds each time as it might pick up other points of light as the Earth rotates. I found out my little Olympus T-6 has this design and I think I can piggyback it on the gear drive. I follow Trevor Dobson on Flickr as he seems to do these burst shots when filming the Milky Way in Australia and he uses a DeepSkyStacker program to align all the images. I’m wondering how burst shots would do with the comet.

Glad you liked it. I started taking astrophotos when I was a teenager in the 1980s. I use to do piggyback shots with my old Mamiya 55mm camera. It was on top of my scope which was guided by a clock drive that could track but not very good. Then my career hit and I stopped until I retired. The technology has completely revolutionized astrophotography and it took two years to learn how to do it. It is also pricey. My setup cost almost 10,000 bucks and that is a low budget range. Cell phone apps can stack multiple images quiet effectively. Comets don't require long exposures but they take some time processing because the comet is moving different relative to the stars. Galaxies and comets are my favorite and I have photos of over 200 Galaxies and probably 20 to 30 comets.
