After aligning the "digital finder"* with the main scope using Venus, I was able to use TSXPro to locate the galaxy by image linking on the autoguider's image by taking an exposure in TSXPro using the autoguider camera (QHY5L-II).

*QHY5L-II/SV50 autoguider combination, along with the Orion 2x Shorty Barlow.
Image link stats indicated a scale of 3.60 as/p, with the camera binned in the ASCOM set-up.
