Cut short by clouds!   I have been wanting to get this object, too.  It was finally in an area of the sky and there at the right time for me to get at least 90 minutes worth of time on it.   But, the clouds came in and ruined things only half-way in.   What I did get was decent, at least.

M101 Spiral Galaxy

M101 on Feb 29, 2020 UT. 206×30 sec, Gain37, Offset 15, 116×60 sec, Gain 20, Offset 15, QHY183c at -20C, UHC-S filter, Televue TV-85 at F/5.6.

Two sets of data taken back to back.  First set was with 30 sec, high-gain sub-images and the 2nd set was with 60 sec subs at medium gain.   Total time was 3.65 hours.   Cropped about 50% out to isolate the galaxy.  The 60 sec subs were better, but only because I had centered the target better and it was higher in the sky when I started the set.

Jellyfish Nebula – IC 443

IC 443 on Feb 29, 2020 UT. 276×30 sec, Gain 37, Offset 15, QHY183c at -20C, UHC-S filter, Televue TV-85 at F/5.6.

First object of this night’s session was an ambitious attempt at the Jellyfish Nebula.  Over 2 hrs and it still was not enough.  I was hoping it would pick up more.  The L-eNhance filter might do a better job.   For nebulae, it is definitely more sensitive, just not as versatile as the UHC-S filter is.
