M31 Andromeda Galaxy with transit of 372 Palma Asteroid

This image of the M31 Andromeda Galaxy was taken on 10/21/11 in northern Illinois. I was lucky to capture the Asteroid 372 Palma briefly "streaking" over Andromeda Galaxy. The Galaxy is located over 2.5 million light years from Earth, while 372 Palma resides in the Asteroid Belt between Mars and Jupiter. The size of the Asteroid is about 116 miles in diameter while Andromeda Galaxy is estimated to be 220,000 light years in diameter! Included in this view are (2) other Satelitte Galaxies of Andromeda: The round dwarf elliptical Galaxy M32 and below that is the other dwarf elliptical Galaxy M110.

I used (83) images in which each sub was (3) minutes in duration. Total imaging time was from 10:45 pm until 4:15 am in the morning. Maxim DL 5.1 Astronomical Software was used to capture all the photo files. Afterwards, I took (30) Flats and (30) Bias Images along with (10) Darks. All (83) Images were Calibrated and Color Corrected using Maxim DL and then they were Stacked & Aligned. Much time was spent in Photoshop going through several iterations of balancing the proper colors, sharpness and highlights. I also created a short video of the Asteroid moving over Andromeda - that video is in the same folder as this one. Check it out.

Equipment used was: Celestron Nexstar 11 SCT with a Mitty Wedge, Hyperstar III, Starlight Xpress SXVR-M25C with an IDAS Filter, Stellarvue Raptor Scope with a SX Lodestar Guiding Camera, Starizona Remote MicroFocus, Icron Powered USB, Maxim DL 5.0, Starry Night Pro, Adobe Photoshop CS5.1, ADM Mounting Hardware, Sony Vaio Laptop (High Res Screen Graphics), and my Backyard under Dark Skies.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
