Imaging the Messiers for the Astronomical League
(Imaging Messier Observing Program)
Updated 05/05/24 05:05 PM -0400

Seeing what the ZWO SeeStar S50 can do for this classic list of star clusters, nebulae, and galaxies!
All images are 2-5 minutes of live stacking unless otherwise noted.

 All images are taken using a ZWO SeeStar S50 (50mm refractor at 202mm FL with the IMX462 imaging chip) at Deerlick Astronomy Village, Sharon GA (33.553879, -82.761069). Time and date stamps, plus exposure times, are shown in the image watermark. Images below are just the jpgs produced by the SeeStar (not the fits files) that I've only minimally post-processed. Initially I only tweaked them using my phone apps but as the project progressed I discovered that it actually took less time (<5 minutes total) and gave better results to do a 1-click Topaz DeNoise followed by 1-3 clicks of simple adjustments in Photoshop CS5.

Bonus: Asteroid Vesta was travelling through the neighborhood and graced us with a cameo appearance! I've labeled her in the shot.

M12 Dimmer and looser than M10, this glob still sparkles! It is rather asymmetrical and looks like a cross between an open cluster and a globular cluster. It has short stubby strings of stars crossing the center at different angles. An interesting arm of 4 stars curves up around one side (at the bottom right of the core in this framing).  14.5 16000 16h 47.2m -01° 57′ Oph summer

M31 This is just the center of our massive sister galaxy M31. Prominent dust lanes are evident, giving nice spiral structure to the arms. M32 lies to the upper left and M110 to the lower right. I hope someday Seestar will have mosaic mode to make it easy to combine all three galaxies into one large panorama. 178x63 3 million 0h 41.8m +41° 16′ And autumn Andromeda Galaxy

M35 The was the first star cluster I could reliably find in binoculars when I started learning the sky. I just looked for Castor's fuzzy soccer ball, sitting just off of his foot. Overall the cluster is elongated, almost vase-like in shape at low mag and manages to stand out in a busy field. 28 2800 6h 08.9m +24° 20′ Gem winter

Messier 40 field labeled Messier 40 is simply an evenly-matched pair of stars, now known as Winnecke 4. This duo sits underneath small galaxy NGC 4290 - could that possibly be what Charles Messier meant to record? (Seems too small & dim to me for his possible detection but I could easily be wrong!)  Four other NGC galaxies are in the field. I had not noticed the lower three NGC objects before. 0.8 510 12h 22.4m +58° 05′ UMa spring Winnecke 4

M44 This is "the Beehive" open cluster, where I'm assuming the dozen brighter stars might represent the closest/bigger individual bees and the dimmer ones represent the buzzy bee cloud (!). It is a loose cluster and has been known since ancient times. It can be spotted as a fuzzy spot by naked eye (in good skies). It is thought to be roughly the same age as the Hyades (625-790 myrs old) and shares the same proper motion direction. 95 577 8h 40.1m +19° 59′ Cnc winter Beehive Cluster

Much more distinct than M46, this cluster features 5-6 brighter stars scattered among smaller stars. Four of these bright stars sit in trapezoid shape and define the center of the cluster.

Messier 49 is a bright slightly elongated elliptical galaxy with an even, diffuse haze surrounding it. No other detail can be detected.

Messier 100 is a beautiful face-on spiral, somewhat reminiscent of M99. St Katherine's Wheel. It has two very nice spiral arms sitting opposite one another as they curve around the bright central core. Bulges and knots are evident in both arms. A lovely swirling haze surrounds the arms, echoing their motion. This galaxy sits in a nice field with four other companion galaxies, NGC 4312, 4323, 4328, and IC783.

Longer (and therefore brighter) exposures tended to blow it out and made the shape harder to detect.

Big and bright M106 has its face angled very slightly away from us, revealing its spiral interior. One bright arm stands out from the rest and seems to be paired with a dimmer arm directly across from it, giving the structure a diffuse "Z" shape. It is thought to have a supermassive black hole in the center. 19x8 25 million 12h 18.9m +47° 19′ CVn spring
