IC 1396 - Elephant Trunk High Resolution

Running low on targets from my small patch of suburban sky means sometimes revisiting previous targets with different equipment and perspective. My previous Elephant Trunk was a more of a medium-size field with a refractor, and this one more up close and personal with the iDK, albeit reduced to 1600mm. Still, at .49"/px I think that qualifies as pretty high resolution. Or at least the highest meaningful resolution I can get from my backyard.

I almost exclusively use the iDK reduced to f5 and 1600mm with the Takahashi Reducer CR .73X. I've been asked why I would shoot even small galaxies with the reducer and not the full native focal length of 2130mm and f6.7. My feelings are I don't believe I can use any more resolution than what I'm getting now because of my location and average seeing. I might get below 1.5" seeing on occasion, but not frequently enough to justify giving up the speed of the reducer. It may not seem like much, but based just on the f-ratio difference I only need 56% of the exposure time with the reducer compared to what I would need at the full f6.7.

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.
