20170610 Jupiter

Transparency 7/10, seeing 4/10.

C5 with 2x barlows, ASI 120mm

1412 UT, I've aligned by Rigel with the C5, hopefully will make future alignment faster.

Still wonder if I shall keep a C5, or go for a smaller refractor?  I don't know indeed.

Cloud come and go, it's just crazy to do imaging like this:

I waited for so long just to align the mount with Jupiter.

I waited for another cloud gap for *brief* collimation.

And then I waited very long to capture a prime focus one, taken at 1401 UT:-

And then I realized the cloud amount was reduced, so I wait to capture with a 2x barlows, taken at 1410 UT, no more detail could be shown:

Moving cloud could imply poor seeing.

It's far more comfortable to shoot indoor!

A new project: resuming Home@Walnut observation

It's raining today, and thus it's probably the end of the three consecutive clear nights.

Last night I setup my Nexstar + C5 in the old location where I observe indoor, and it's workable.  So, I should begin the migration, i.e. to move all my gears there.  I shall move one of the plants to my office, and then the rest of the plants will be placed on top of the dry box.

Another project is the motorize the focuser of my C5.  Previously I was thinking to sell it, and replaced it with my modified FD 300mm 2.8, but then it's no good at high magnification and so I will keep my C5 and further enhance it.

Tentatively, I will use one of those small motors, add brass gear on the focuser, and then drive it like the Sky Adventurer.  Let's see.
