Aggregated observational attempts

(23/6) Friday night: Did some Jupiter with Sky90, seeing very poor and Jupiter sometimes lost its shape

(24/6) Saturday morning: it's indeed the above session as above, just passed the 00:00 mark. Attempted to capture the deep sky objects near the tail of scorpius. With the widest lens, that area shows many stars even at 1/2s exposure. Far more than visible than naked eyes. Several faint fuzzy can be seen.

Centered M7 and use the 75mm f/1.8 lens, the field is nicely filled with stars of the cluster, with a little bit empty space around, super good! I'm very impressed with the sensitivity and the ease of use. Portability is also superb! Very rough polar alignment needed since it's just ~12s exposure longest. Direct feed into registax reveals on field rotation over 3 minutes of exposure with individual 8.5s exposures. Tried to center other faint fuzzy but nothing revealed, either due to poor sky or non-matching image scale.

(24/6) Saturday night: tried to capture Jupiter with C8, but failed, for I failed to point at it... either side of the meridian. So, should give up.

25/6 Afternoon: tried to point to the sun, but viewing angle was so poor. It also reveals that a remote setup is not going to be very rewarding... at least during some period of the year.
