Not quite finished yet, but I have converted my h alpha scope to double stacking. It definitely needs some tuning of the filters to work properly. And probably something else too. But it definitely looks promising, as the following 2 hour timelapse shows. Click on the GIF to view larger and more detailed. Enjoy!
Clear skies = sun timelapse. Same gear as always. But slightly different processing and sharpening. The result was better than usual me thinks.
Long time since I have done anything here. But yesterday, I managed to film some very nice prominences. One was a giant loop that flung out of the surface of the Sun. And on the other side of the Sun, I found a "waterfall" prominence. I shot all of this with my homemade 5" h-alpha telescope. Using a ASI178MM camera. I used gain 350 and 10ms exposures for the prominences, and gain 200 and 7ms exposures for the surface. Stabilization was a bit tricky, but with a combination of imPPG and PIPP, I managed to get them semi-stable. All timelapses covers about 1 hour. I did them longer, but guiding failed midway, so they started "wandering", cutting the timelapses short.
Last night, the skies finally cleared without the risk of sudden snow. So I decided to whip out my Klevtson and pull a timelapse of Jupiter. According to the stats, the GRS would transit during the timelapse. And there it was. Unfortunately, some clouds, both thin and thick, passed in front of Jupiter. So the processing was a bit distorted. And thats why the timelapse looks like it is "blinking" at times. But all in all, I am satisfied with the result. The timelapse is taken over the course of about 2.5 hours.
Tech details : 200mm Klevtsov-Cass, ASI678MC camera at 200 gain and 4ms exposures. Approx 100 30 second movies. Stacked the best 50% of the images. Stacked in AS!3. Wavelet and rgb balance in Registax. Animation in PIPP.
Yesterday, the "boring" prominences from the day before suddenly blossomed and became quite active. Sputtering plasma around. Unfortunately, some clouds rolled in, so I had to cut it short. But later in the afternoon, I started filming an area around a sunspot. And I am glad I did. It flared up at the end of my run. The Sun was getting low, so there was a lot of turbulence. But it is still acceptable quality.
When I checked the Gong network today, it was obvious something was going on all around. So I couldn't decide which prominence to film. And I decided to go wideangle. After the filming, it was obvious that the newcomer, although bright and powerful, didn't have much in the order of dynamics. So I should probably have just stayed with the one from yesterday. But here is the both of them.
I also added one photo to show the size compared to the Earth. Earth is shown in the little image on the sun. Click on the image to zoom in.
