Here comes the Sun!

Post by rwilkinson » Sat Aug 08, 2015 8:13 pm

Even if we didn't get much of a view of the Sun last Tuesday, it made a better appearance this afternoon, allowing me to experiment with our Trust WB5400 webcam on the back of my TS70ED refractor.
With its 420mm focal length, I could just fit the whole Sun onto the CCD:

I used the AutoStakkert! program (as recommended by Damian Peach) for stacking and then exported a .TIF file into IRIS for the wavelet filtering.
I used a "white light" filter (made from AstroSolar film) on the front of the telescope, and the video was shot in monochrome, so I added the "warm" colour-balance using IRIS.

Good shot!
Celestron 11" Telescope
Eq6 Pro Mount
Eq5 Mount
EQ Mod
QHY5 Guide camera
Cannon 1000D SLR Camera

I choose to image with an 11" SCT Celestron in this decade and do the other things, not because they are easy, but because they are hard......

The "quiet" side of the Sun was turned our way last weekend, but today there was a very active sunspot area on view:

Here comes the Sun (in Norfolk)

Yes, we did get to see a fair amount of Sun from the Norfolk star-camp this year. 8-)
Although it was raining when we arrived on the Tuesday, by the following day (Weds 9th) it had cleared up nicely, so I tried some solar imaging:

Then the following day I borrowed Keith's Lunt solar telescope and had a go with that:

(The sun was even quieter by then, so I increased the gain in processing the prominences to see what I could detect)
