Here are some more images from last weekend. Usual set-up, usual processing. Click on the images for a larger version.
This is a three pane mosaic showing just the Proms.
This image shows the effect of the different end of the frequency range of the PST.
And lastly most of the activity was in one central band, so I took half a dozen movies and created a mosaic strip.
Saw a great piece of processing on SGL a few weeks ago and just had to try myself. This involved inverting the Prom portion of a solar image so that there is a white background and then colourising… very odd, but strangely appealing!
From 28th July 20112
I sat out in the sun taking AVIs every 5 minutes for nearly 6 hours. I even managed to cook a bbq while doing it 🙂
This is the end result of 54.2Gb of date captured over 6 hours, I used a different capture program this time, called “Dave’s Solar System recorder” – still getting to grips with that, but a lot of potential.
Each AVI was stacked in AVI stacker, wavelets in R5 and further processing in CS5. I then used “Dave’s video stabilizer”. Don’t know who Dave is but he writes cracking software 🙂
Had a nice sunny weekend and managed to get out with the scope on both Saturday and Sunday. The plan for Saturdays was a complete ring of fire… But I missed a bit 🙂
17gb of data 20 AVI’s. Usual software… Captured using IC Capture, stacked in AVIStack, wavelets in R5 and colour/levels/curves in CS5.

Another image of AR1520, same as previous details – just slightly further around the disc…
AR1520 in Ha.
Using AVIStack I have no idea if it uses all the frames, or a certain percentage… or if it uses bits from everyone. Whatever it does it seems to do quite well.
I still use Registax for wavelets, although that’s just laziness as I haven’t learnt to use then in AVI Stack yet! This is AR1520 the same region that NASA has been following and taking some spectacular images. Here is one of mine…
Scope: PST
Camera: DMK21 (with barlow element to get focus)
Stack: AVI Stack
Process: Registax/CS5
Solar prominences.
Captured with DMK21/PST, in a very quick window of opportunity. The clouds clear at 15:30, I was setup captured some AVI’s and packed away before it rained at 15:50 🙂
There was another prom on the rim a little further to the south, but I just didn’t have the time to get another capture…
Stacked in AVIStack which I’m preferring to Registax quite a lot now!
I got a “C” thread extension from the nice man at Firslightoptics, so that I can get my 300D and lodestar par focal.
Today is the first time I’ve managed to get the scope out in months…
Let’s hope that my measuring skills are up to it 🙂
The image itself isn’t new, but what about the presentation? Do you like it better than before?
Found the grid at http://solar-center.stanford.edu – must really ask permission, will do that tomorrow.
You have to tune a PST to show the detail that you want, I’m not really sure what the different tuning positions mean – I think it relates to which part of the sun (surface or above the surface) your seeing. But they definitely do show different things.
These three images show the different ends of the tuning and one in the middle. The left image is close (but not quite) to what you would see in white light, this I believe it close to the surface of the sun. and the one of the right show the boiling atmosphere of the sun which would include the prominences.
