I imaged Jellyfish supernova remnant IC 443 for 11 hours last January from Casa Grande, AZ. I got 114 5-min images, and it all went very well.
I tried to go back and model that night in SkyTools so see what it would have recommended, and how its projected SNs would align with my actual collections (my ground truth).
But for some reason the system cannot reach any SN at all:
Am doing something wrong, or is the database perhaps missing some info required to do the SN calculations?
Thanks.

But for some reason the system cannot reach any SN at all:
- Filters can't reach a target SNR in a New Imaging Project / Exposure Goals tab
- As shown in attached, Exposure Calculator shows no detectable signal.
