NGC 672 and IC1727 with a 6 inch telescope (Andreas Zeinert)

NGC 672 and IC1727 with a 6 inch telescope

The beauty in this picture lies more in the challenge to image these small galaxies with a simple C6 Schmidt Cassegrain at f/8 than in the aesthetic outcome itself. It was a sort of test shoot for my C6 Nextstar that I bought recently. I discovered this object by accident when surfing on the Aladin Atlas. It is not far away from M33. I was surprised that there are only a few photos of this object in Astrobin so I decided to give it a try.

The exposure time is a bit short for the f/8 ratio and one can guess the limit of resolution of my set-up. Seeing according to PhD was about 0.5". More time and Drizzle might have been useful. Nevertheless there are some structures revealed in the galaxies. I attached a professionnal picture of the DSS2 catalogue; as you see there is not so much signal... I did not push further and resisted at any temptation to "sharpen" the galaxy cores, this would have added artefacts for sure. I am not sure what do you think but I also love these tiny galaxies in the background.

Extract from Wikipedia :"NGC 672 is a spiral galaxy in the northern constellation of Triangulum. The original object designated NGC 672 was discovered by the German-born astronomer William Herschel on 26 October 1786, but this was later cataloged as NGC 614. The object now identified as NGC 672 was discovered by John Herschel on 11 November 1827.This galaxy is located at a distance of approximately 23.4 million light-years from the Milky Way, where it forms an interacting pair with the irregular galaxy IC 1727. In the neutral hydrogen radio band, a tidal bridge is observed between the galaxies. NGC 672 appears to be the more massive of the two, and hence IC 1727 shows more distortion from the interaction.

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.
