Tadpole Galaxy Arp188

Svbony 550 122mm with field flattener - Focal Length 854
Canon T5i - not modified for astrophotography; Svbony Colour Correction filter
AVX, ZWO 30F4, ASI 120mini
203x2min subs @ ISO 800, the best of 390X2min subs, for 6.75hrs imaging plus calibration frames

This is my first image produced using the 1.0 field flattener - utilizing the full focal length of the telescope. I am trying a less restrictive light pollution filter than the usual CLS filter.

From Wiki: The Tadpole Galaxy, centered in the image, also known as Arp 188, is a disrupted barred spiral galaxy located 420 million light-years from Earth in the northern constellation Draco. Its most dramatic feature is a trail of stars about 280,000 light-years long. Its size has been attributed to a merger with a smaller galaxy that is believed to have occurred about 100 million years ago. The galaxy is filled with bright blue star clusters triggered by the merger, some containing as many as one million stars. It is the largest disrupted spiral galaxy of its sort.

Yes, I captured photons from a galaxy that is 420 million light-years from earth in my backyard with two fat fingers of whiskey in a tumbler....imaged with sufficient detail that the tail is visible!

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.
