Unusual and sharp detail in this one.

Notable prominences today

The prominence has changed from the image taken a couple of hours previously

This was the first light for my new setup. 4th July 2011. A 127mm Evostar refractor modified to accept part of my PST (Personal Solar Telescope). The sky was somewhat hazy and clouds approaching so I was rushing to get at least some success. Focusing could be better too. Anyway, captured a large prominence on the NW limb at 08.46 UT. With more practice, the images should improve.

Used my more recent Imaging Source DMK 21AF04 webcam to capture this large prominence on the limb of the Sun. Decided to try to colourise the sky near the limb for effect. Taken at 1443 UT. on May 27th 2010

Image of a sunspot group taken at 12.56 UT on 17th May 2007. Short breaks between clouds. 5 FPS for I minute at an exposure of 1/1000 sec. Processed in registax 4 and final tweak in Photoshop

This is a sequence of images of the Sun beginning at 09.22UT, then 13.00 UT, 14.50UT and finally 16.20UT. They show the changes in the prominences on the limb. Each was a sequence of 600 frames at 10fps and 1/33sec exposure.

This was a combination of a surface image and one showing the prom. Combination was done on Photoshop. 19th Feb 2006.

Taken at 14.22 UT on 19th Feb 2006 The East limb has some activity with a few prominences in view. The surface showed very little activity - just a few filaments.

This image is of a prom on the east limb at 11.06UT. By 14.28 it had changed noticeably.. 21st Jan 2006

Sun's Surface at 13.15UT on 20/1/2006

The Sun at 12.29UT on 17th December 2005. Another go at this target. Settings for the prom were the same as below. The surface was imaged using 10fps, Brightness 100%, Gamma 0, Saturation 5%, shutter 1/500, gain 5%. Captured using K3CCDTools and processed in Registax3. In both cases, all 600 frames were stacked. The two images were then superimposed in PS and cropped.

The Sun on 12th December 2005 at 14.01 UT. My first attempts at the Sun using my new Coronado PST telescope. Settings were 10fps, brightness 100%, Gamma 0, Saturation 20%, Shutter 1/33 and gain 20%. Had to overexpose the surface to capture the prominence and so I then blacked out the surface in PS. Image captured in K3CCDTools and processed in Registax 3. Camera was in Normal mode. Best 500 of 600 frames stacked.

Taken with the SXV-H9 through my Coronado PST. Single exposure of 0.005 sec at 14.38 UT on 2nd May 2007. Image acquisition with AstroArt 4 and processed with Photoshop to produce the colour.

Decided to try using the SXV-H9 to image the sun rather than using the webcam. I needed to use a neutral density moon filter to reduce the glare but was able to find focus using a Scopetronix Maxpower lens. Unfortunately the whole image can not then fit on the chip but ok for a first try. The exposure was 0.005 sec and was taken at 09.43 U.T on 27th Aug 2006. Image acquisition was by AstroArt3 but all processing was done in Photoshop.
