Saturn

Acquisition type: Lucky imaging

This is not the greatest shot of Saturn, but it is my best so far after a year of trying on and off.

SkyWatcher EQ6-R Pro Mount

SkyWatcher SynScan WiFi adapter

iOS SynScan Pro app

Polar aligned mount

3 star alignment

Goal Zero Yeti 150 power

Astro-Tech AT115EDT

Astro-Tech Spacer 80mm

Televue PowerMate 4x

Generic Bahtinov mask

Astro-Tech finder

Canon T3i stock

ISO 3200

75F

No moon

80mm spacer. Could probably do the 80+35mm spacer and bring the focuser in farther. Focuser at 60mm.

Canon T3i video mode:

1920x1080 30 FPS with 10x digital zoom with DISP button in video mode

Seeing quality was pretty bad with lots of atmosphere waves. Shot 5 minute videos. The videos honestly looked terrible, wavy, and tons of RGB grain. I doubted anything good at all could come out of it. I was amazed to see something this good after the PIPP/RegiStax/GIMP. The GIMP editing was essential to sharpen the blurry RegiStax output.

PIPP

RegiStax

GIMP - Sharpen, Levels, Brightness

So this was a test to see if I could do planetary with a 115mm refractor, and I can. It is not the same quality as an SCT, but I can get there by stretching magnification with the following optical chain:

AT115EDT + 80mm Astro-Tech spacer + Televue PowerMate 4x + PowerMate camera adapter + generic T ring + Canon T3i

Then the trick is using 10x digital zoom on the T3i in video mode. Hold the DISP button up front beside the ISO button, then press +/- zoom to get up to 10x.

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.
