I was trying to image Jupiter and Saturn for the first time last night. The weather was clear - no wind. I'm located in south east Pennsylvania.
Here's my equipment:
Celestron Nextstar 8SE
ZWO ASI120MC camera directly attached to the scope (no diagonal)
I am using the default mount that comes with the 8SE
The ZWO is connected to my Windows laptop running Sharpcap 3.2
I didn't really bother doing a 2-star or a 3-star alignment since Jupiter is an easy target, so I manually panned my scope and focused till the planet appeared in my laptop
However the moment it appeared, it seemed to diagonally move across my line of sight and disappeared within 1-2 seconds. I had to pan again to get it to appear and the same thing happened immediately.
This happened with Saturn as well. I could see the rings and then bam - it moves across and disappears
I just could not keep the target steady in 1 location which was extremely frustrating. I am not touching the scope and it is on solid concrete ground.
Why would this happen? I would like to try again tonight.
