NGC5905 &NGC5908 Galaxies

These two galaxies, NGC 5905 (upper left) and NGC 5908 (lower right) lie about 140 million light-years distant in the northern constellation Draco. Separated by about 500,000 light-years, the pair are actually both spiral galaxies and nicely illustrate the striking contrasts in appearance possible when viewing spirals from different perspectives. Seen face-on, NGC 5905 is clearly a spiral galaxy with bright star clusters tracing arms that wind outward from a prominent central bar. Oriented edge-on to our view, the spiral nature of NGC 5908 is revealed by a bright nucleus and dark band of obscuring dust characteristic of a spiral galaxy's disk. In fact, NGC 5908 is similar in appearance to the well studied edge-on spiral galaxy M104 - The Sombrero Galaxy. [Source: APOD].

The image was captured with the venerable Meade 12"LX200, using the Atik 383L+ mono at F7.16 (i.e. 2182mm FL). Astronomik's Luminance, Red, Green and Blue filters were used. Subs were taken at 1x1 bin, -10C, and 600 seconds each for L, and 300 seconds each R, G and B.

Image 2016 --

Lum 600s: 14 subs (2.33 hr) on Jul 2nd, 5th and 10th.

Red 300s: 10 subs (0.83 hr) on Jul 6th.

Green 300s: 11 subs (0.92 hr) on Jul 7th.

Blue 300s: 14 subs (1.17 hr) on Jul 7th and 10th.

Processing was done with PixInsight, following (for the most part) kayronjm's tutorial of Feb. 24th, 2013. Filter L was used to develop the Lum image. R, G and B were collected for the color mix. North is up, and this is a very slight crop due to the misalignment from dithering.

I suspect the summer's high humidity along with shooting over Burleson's city lights causes the problematic internal reflections.

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.
