M94 in LRGB with RGB Stars on a limited sky budget

Between time spent tuning the FLT132 and limited clear skies, I was still able to pull together a few subs to produce my first M94 photo. Not bad for less than 2 hours integration. You can see that I am playing with exposure lengths to settle in on future levels. Having a few issues with the OAG guide setup losing the guide star, so I'll continue to tune that. This and trying some 15 min exposures (that mostly star trailed due to the guide star drops) cost me a few hours of subs. Clouds rolled in ahead of original forecast and left me with the small sub count, especially RGB.

The HAE43EC has been stellar with guiding often below 0.5 total RMS without much effort and on these average seeing nights. Can't wait to set it loose on a great seeing night. I am now planning to replace my GT81 mount (EQ6R-Pro) with the HAE29EC. Ping me if you are looking to own a pristine EQ6R-Pro.

I also used a portion of this shoot to redo auto-focus backlash and filter offsets. Turns out I was way off before, but it didn't really show until I hit the narrow band filters. I still need to run offset calcs for OIII and SII.

Hope you enjoy this bit of M94 exposure. Clear Skies.

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.
