First night of my 3rd C5

The first one was sold but I soon wanted to get another one.

The second one was a lemon and I soon returned it.

The third one has arrived for a few weeks maybe, but I just managed to get some star lights to fall on it. I colliminated briefly and stars were pinpoint.

Cloud moved in and out so that I cannot really fine tune the collimation, or I can really observe with it. But at least I know it's not a lemon. The last one could not form any decent image even for day light target.

Wish that I can have time to really try it out, it shall stay with me for a pretty long time.

Thank God for the sunshine today, it has been so wet these days and the sunshine should drive the humidity lower.

Prominence activities were pretty good today, and a small but strong group was at the bottom and a pretty long one could be seen near the top. AR1175 could be seen clearly and signs of new (or remnant?) active region could be seen over the solar disc.

Seeing pretty poor at 2/10, transparency 3/10.

I tried to setup my telescope twice today, the first attempted failed since cloud covered after I setup my stuff... After seeing the completely covered sky, I packed up my stuff... and then after around half an hour, sunshine came in my home and I setup my stuff again.

Seeing 4/10, transparency 2/10.
