Shawn, Kent, and I had a nice crowd last night under cold (though not as cold as Wednesday night). We were curious how many people would stay to look through the telescopes after the show. Well we act

Attached are the February sky materials from the Astronomical League.

If you have a SCT or refractor I've made it easier to manually move the scope around. Since there is no way to add a handle to my telescope mount's tube cradle I glued a knob to the bottom of the star

I’ve always felt we often overspend on diagonal mirrors, or star diagonals for SCT and refractors so I ran a few test. I compared how the 6th star in the Trapezium in the Orion Nebula looked and also

I’ve received a mailing list notice that Gary Myers, head of StellarCat, is retiring, and so production of ServoCat GOTO systems will be ending soon. But Wildcard Innovations, the Australian company t

One of my favorite targets for this time of year. Conditions weren't terrific but it was great to get out. This one is NGC2264 also referred to as the Christmas Tree or Cone Nebula. Cheers Ian NGGC226

James Webb telescope reaches its final destination in space, a million miles away James Webb telescope reaches its final destination in space, a million m... The $10 billion telescope is nearly ready

There’s a huge prominence on the sun today (Monday Jan 24) in H-alpha light.

Can anyone identify the brand of tripod this is? It is very sturdy and well-made, but has a weird "shoe" for attaching a scope or camera. There is a logo on the side, but no brand name or manufacturer

Chesapeake city operations are closed Saturday and Sunday. So we will have to cancel Skywatch tomorrow due to weather and safety concerns.

I noted the very bright central peaks of Longrenus last night and have tried to follow up on the reason. Not a whole lot of luck but I believe the very bright patches were real and not due to solely l

I was getting in a quick lunar session tonight between the building clouds. I noticed that the central peak complex of Langrenus on the eastern limb has a very bright reflective appearance. There is s

It was cold last night, dropping down to 25 degrees but the sky was very clear with excellent seeing. The downside was a full moon. That’s not too much an issue when observing double stars though. Fir

Our order has arrived, and I have a hat, a T-shirt, and a hoodie for Leah Flax and 2 T-shirts and a hoodie for Brian Lafitte. We also have a variety of T-shirts for sale at $12 apiece. Sizes and color

Asteroid 1994 PC1 is about to zip past us: https://skyandtelescope.org/astronomy-news/see-a-large-stony-asteroid-race-across-the-sky/ Roy

I posted this on Facebook and it seemed to help others decide to make their own. Maybe it will help others here as well. Samantha Erb inspired me to make my own James Webb Space Telescope mirror after

Last night, against predictions, under cold windy skies, we were rewarded with the perfect seeing night. Literally a ten out of ten. Sirius looked like a steady spotlight with no scintillation whatsoe

Most of us prefer "fast" telescope ratios. With fast systems, such as f/4 to 4/6 telescope tubes can be shorter, important for transporting our instruments to dark sky locations. There are exceptions,

Lots of activity today on the sun. Excellent examples of solar flares are now on the face of the sun. Very hot regions around unstable sunspots. Good large loop prominence is also on the limb. The fac

Hope you got out tonight Ian. Another banner night for seeing. The weather here was odd in that there was a haze all day long artificially created by a zillion jets making contrails. Those contrails s
