Comet C/2023 A3 (Tsuchinshan-ATLAS)

Comet C/2023 A3 (Tsuchinshan-ATLAS) has indeed become very observable with the naked eye after all. It can be photographed quite well with smartphones. Of course, a camera with a larger aperture provides a better image, not to mention the quality lenses. How to find the comet in the sky is described quite well in the Sky and Telescope article  Comet […]

Root River Park 2024

Root River Park is located south of Rochester and is owned by Olmstead County. It is a small but pretty park adjacent to the North branch of the Root river. Rochester residents don’t use this park much and that’s a shame. However, this park is beneficial to amateur astronomers. The sky is dark enough to observe faint objects on a […]

Aurora on May 10, 2024

The night of Friday, May 10, was the first night for club members under the dark skies of Eagle Bluff after a long winter. To our surprise, it wasn’t even dark yet and already we saw something very special – the Northern Lights, and even in the south. A few minutes later, while it was still dusk, the International Space […]

        Hello Randy

        Minutes reviewed; thanks.  (BTW the last name is spelled Fealey).  Jay and I have done an initial cleaning of the AT80ED refractor.  I have a brief Power Point presentation on our efforts I will send it to you either here as an attachment or via your email.  Haven’t had it mounted for a star diffraction test but have viewed some terrestrial objects and photographed some distant signs through the scope.  Would wonder if you have a Vixen saddle on one of  your scopes so we might attach it to a motorized scope and check it out more thoroughly.  Otherwise we can reconnect the scope to the Sky Watcher mount head and the tripod (? the one Jerome has now).

        The pptx file is attached.

        Thanks Randy
