Laptop Screen Too Bright During Night Sky Session?


If you do night sky observing or astrophotography, you learn that your eyes adapt to the night sky, but bright lights quickly thwart the vision. Using red lighting is suitable for seeing objects and retaining the night vision. Use a clear plexiglass sheet over a laptop screen to achieve a night-sky user friendly interface.

Sky Objects, Mostly Moon Shots


The pix in my YouTube collection are from having used mostly two point-and-shoot cameras. Incidentally, smart-phone cameras also have capabilities for taking similar sky pix.

For people who haven't considered photographing sky objects, look, up in the sky. It could be Supermoon! Build your own pic collection for day or night moons! Also, pick other sky objects that catch your fancy. Read the entire article and comment there, please.

Astro Imaging Session Piques Three-item Topic

What arose when the sun set down at the dark site we went to? Dark skies and objects (constellations, star clusters, nebulae, ...) that don't show up well in light-pollution, densely populated areas. What three items am I talking about? A TV tray table, a transparent cookbook stand, and a thin, portable gaming monitor. Read the entire article and comment there, please.

April 8 2024 Total Solar Eclipse (44-sec capture)

Why only 44 seconds instead of reported totality of 2 minutes and 35 seconds? Clouds interfered with and distorted the capture, eventually totally obscuring the corona after ~43 seconds. Read the entire article and comment there, please.

2-Saturn Composite, Anticipating Future Edge-on Rings

We recently pic'd Saturn, then recalled another imaging session (from about 26 months before. I wanted to compare images, then create a composite. The 2-Saturn composite image shows Saturn on 9/2/2021 and 11/22/2023. The orientations differ, and the newer Saturn's set of rings angle narrower than the rings of the earlier Saturn.

Partial Annular Solar Eclipse Oct 14 2023, Austin


Our area (Austin) was fortunate enough to behold a partial solar eclipse, clear skies and all. Texans in San Antonio, about 100 miles to the south, got a fabulous annular eclipse because of that area being in the zone of annularity. Read the entire article and comment there, please.

DIY Red-Llght Head Light



You might ask, "Who would want a red-light head light?" Well, amateur astronomers, for hands-free seeing at night, especially if they're carrying or handling equipment, such as telescopes. Other night-sky observers might want to wear them for being able to walk around without bumping into people or items, and they can retain night vision while viewing objects, whether through telescopes or binoculars at night-sky watching events.
