The Moon and Venus

 During twilight on Saturday evening (18 April) the 1.7-day crescent moon passed within 5.5 deg of the planet Venus.  The conjunction was photographed with a Sony A7iii camera and Olympus OM 135mm f/2.8 lens, and an Olympus E-M1iii camera and 75mm f/1.8 lens.  Both cameras were hand held.

A nearby star cluster and two nearby stars

The centerpiece of the constellation Coma Berenices is the open star-cluster known as Melotte 111, or the Coma Star Cluster.  At 280 ly distant , it is the second-closest recognizable open cluster, after the Hyades cluster.

The following images were obtained with a Sony A7iii camera and an Olympus 135mm f/2.8 lens riding on an iOptron SmartEQ Pro+ mount.  The measured sky brightness was 19.77 mpsas (location: Santa Fe).

Melotte 111, the Coma Star Cluster.  

This image was obtained with a Hoya Sparkle-6 filter.  This filter is way too aggressive for a lens with this focal length (135 mm), but it really brings out the relative colors of the stars.  

Here is a finder chart showing the location of Melotte 111 (Coma Star Cluster) relative to other constellations in the evening sky (Big Dipper on the left, Leo on the right):

This finder chart also hilights three nearby stars: Lalande 21185, Wolf 359, and Ross 128.

Lalande 21185 is the fourth closest star system after the Alpha Centauri system, Barnard's Star, and Wolf 359.  It is 8.3 ly distant.

Lalande 21185 (circled), the fourth closest star system.

 

Ross 128 is the 11th closest star system, at 11.0 ly, and magnitude 11.1 (triple 11's!).

Ross 128 (circled), the 11th closest star system.

 Here is a picture of the camera and lens attached to the IOptron mount:

 

 

 

Comet C/2025 R3 (PANSTARRS) from Santa Fe

 Comet C/2025 R3 (PANSTARRS) is visible low in the east at the beginning of astronomical dawn (about 5 am MDT).   The name derives from the Panoramic Survey Telescope And Rapid Response Sytem observatory in Hawaii  Between the neighborhood rooftops, trees, and power lines, getting a clear view is a challenge from my location in Santa Fe.  The comet is currently about magnitude 4.5 and is visible with binoculars.  I could easily see the head but not the tail with a 6x30 binocular.

The following images were obtained with an Olympus E-M1iii camera and 75mm f/1.8 lens.

Venus setting

 Venus, at magnitude -3.9, is currently brighter than Jupiter (-2.2) and Sirius (-1.4).  From my location, Venus sets behind the Bristol Head ridgeline around 8:10 pm MDT.

Zodiacal light over Bristol Head

A clear moonless night was a welcome sight during a brief return to Creede.  The sky seemed exceptionally dark, but I did not have a sky-brightness meter to measure it.  My guess is 21+ mpsas.

The Zodiacal Light is a diffuse glow caused by sunlight reflecting off cosmic dust in Earth's orbital plane.  Most of this dust is thought to originate from the planet Mars.

These images were obtained with an Olympus E-P5 camera with an Olympus 12mm f/2 lens and a Hoya Sparkle-6 filter.

Easter-morning moon

The Easter-morning photo was taken with a Lumix 12-60mm lens.
