Results of Pier Upgrade Described

I poured a concrete pier topped with a Starizona EQ6R-Pro Pier Adapter. I also ran underground conduit for the extension cord and 50ft Comprehensive Company Active USB 3.0 cable to my sunroom. The Veil, Crescent, and North America nebulae were taken using the pier. My findings are that the guiding has improved from 0.9-1.2 arcseconds on the tripod to 0.45-0.65 arcseconds on the pier. On the tripod, after polar alignment with Sharpcap, I would find the quality of the alignment changed significantly as a function of RA axis angle. On the pier I don’t have that problem. My guess is the tripod sitting in spongy grass wasn’t a solid enough base. Also, I only need to adjust the azimuth (not elevation) and aligning with the polar scope results in “excellent” alignment according to Sharpcap so it’s just a confirmation step now. More important to me, however, is that the setup time (from storage in my house to fully operational) has been reduced from about 90 min to 35 min. Another consideration for me is that I don’t have to worry about my dogs messing with the power and USB cables running across the ground. I still have some more optimization to do with cable management, but I’ll get there. Unfortunately, the upgrade hasn’t decreased the number of cloudy nights. -Rich

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.
