--- Comet C/2020 R4 ATLAS:
Things did not go well tonight with poor tracking making star trails. (Since I have to set up each time, polar alignment is always a culprit, but initial evidence indicates some other issue.) Out of 35 minutes on the comet DeepSkyStacker stacked only the first 2 minutes worth, so it isn't very prominent. The best that can be said is that orbital mechanicians can rest easy knowing the comet has been verified to be where they said it would be.
--- Nova Cas 2021 (V1405):
The nova in Cassiopeia isn't moving but it's no better off. DSS stacked only half the pictures, the trails interfering with its stacking. I posted a better image of this object a few days ago taken with only a point-n-shoot superzoom camera on a star tracker while here I had a full-fledged camera on a scope and mount. This image's main virtue is it shows the nova hasn't changed brightness from the other night, so it should still be visible in binoculars if its low altitude doesn't dim it too much.
