20250926 Deep sky imaging resumed

First time after the long daylight summer, I tried to use a LiFePO4 battery to power the setup.

But then the deep sky camera will disconnect itself sometimes, turning cooling off does help a bit, but it does not eliminate the problem entirely.  It will disconnect when the mount slews to another target.  A good indicator that there is not enough power.

I know the problem immediately.

I was using a power cable from a cheap solar panel, and the wire is just too thin.  I made the one below with a 12AWG cable, and I hope it solves the problem.

-- 

Spent sometime to test it indoor briefly, it works perfectly.

Those thin cables shall be throw away, but the clips should be kept.  

I believe I might need a separate power cable for the cooled camera directly to the battery.

Almy said, let's do some stargazing.

85mm refractor, with a large 2" eyepiece for widefield, a 8-24mm zoom and a 3-8mm zoom.

Almach was an amazing sight!  It begins to split at around 10mm, cleanly split at 8mm.  The blue companion is just attractive.

The double clusters, M13, M19, M31.

The ring nebula was not seen.

20250916 Sun

Got some sunshine today, not exactly good but I caught thart moment.  

It rains soon after I packed up my stuff.  I have bought a bigger box to store my EQ mount head so I can setup and pack up rather quickly.

The sun is active, several sunspots can be seen and so many prominences around the edge.

Seeing low at maybe 3-4/10, windy.  Transparency was high during the moments that I took the images.

1342 (UT+1) with reducer for full disc:

1352 (UT+1) with reducer, false colorised.

AR4216 and 4217, ignoring the prominences to bring out as much as detail possible at 2x, taken at 1354 (UT+1)

AR4217 at 1355 (UT+1)

AR4127 with 4221 on the lower side at 1356 (UT+1)

Yet another shot at 1359 (UT+1)

Finally a false colorised one at 1400 (UT+1)

I am happy that I finally had a short imaging session again.
