Description

I recently damaged the RA worm/block on my mount while fitting an Apex reducer to my OTA (foolishly thinking the RA axis was in the locked position). So while I wait for a replacement assembly to arrive from Software Bisque, I've made another processing attempt at my recently posted 9-panel Orion mosaic using Nikon D810 DSLR data kindly shared by Wei-Hao Wang.

Through this widefield processing project, I've come to appreciate just how much dust and reflection nebulosity permeates this amazing constellation!
