So far, I have roughly 2-2.5 hours on Ha on each panel after one night. I'm quite happy with the results on such limited data. Perhaps really good seeing conditions help? So how do you know when enough Hydrogen Alpha data is enough? I plan on adding RGB data to this. Not sure about Luminance at this point. Maybe use the Ha data as a luminance? On this target, is HaLRGB preferred or is HaRGB okay? Acquisition details on the linked website. Let me know what you think. Thanks for looking!
Also, I attached a picture of my "DIY Polemaster" which I used with the Ekos Alignment Module. It's an ASI120MM-S (I also use for guiding), an $8 25mm lens and a used pole master adapter. Total cost was $30 not including the camera I already had. FOV is about 11X8 degrees. I got way more consistent Polar Align error readings with this rather than using the main scope (420mm FL refractor). According to ekos my polar error was 0.48" when I was complete and I couldn't really see the error on the vector since the FOV was so large. I didn't have a chance to really test how good PA was with PHD but all the subs were 10 minutes so I guess it got close enough!
