20260306 Equipment Testing: Canon FD300mm f2.8 on the double cluster + Seestar S30 in EQ mode

Canon FD300 f2.8 Testing:  Other than the double clusters, I have tried a number of other targets as well.  They will be used to demonstrate the lens.

EQ mode testing failed, since the Seestar failed to point at a clear patch of sky when doing the polar alignment.  It keeps resetting its WIFI for unknown reason.  I have given up and pointed it to M81 and M82 for the rest of the night.

1.5hr in total, altazimuth mode 30s subexposures.

My daughter came back and I setup my 85mm refractor on a SVBony SV225 mount for some visual observation.  I have used my Canon 10x30 IS as well.  Very fine session.

I tested a new zoom eyepiece which is better than expected.
