Latest Sunspots 1092 and 1093

After several days of cloud and rain, the clouds parted and I managed to get a shot of the current sun with its sunspots.

These are recorded as sunspots 1092 and 1093 from left to right.

This is not a great image, as it’s a bit blurred. Taken with my homemade DSLR solar filter on my camera using my 300mm lens.

Solar Sunspots and Granulation

I managed to do a bit of imaging today as the Sun was out all day. I went and purchased a sheet of A4 Baader Solar Filter paper from Green Witch the other day, they were the cheapest place I could find, plus I got my SPA discount as well. It also gave me my first chance to visit them in Dry Drayton.

Anyway, I produced a couple of solar filters for my LX200 and my ED80 Pro from the paper sheet so was dying to try them out (which was a nightmare trying to cut, as I couldn’t stop my fingers leaving fingerprints on the paper, plus you need to remember to remove a really thin piece of plastic that is attached to the filter paper).

Both worked really well, I have also just purchased a 2nd hand DMK21 camera, which is so much better than my SPC900 webcam, which I about to sell. So imaging with this was fun as the more practice I get on the DMK21 the better. I also used my Baader Solar Continuum filter which I have had for ages but never really got to use as I did not think that the SPC900 gave enough brightness of the object to use a dark green filter, but the DMK21 handles it with ease as you have a lot more control over your gain, exposure and gamma settings.

The great thing was that I was able to record granulation on my images, something I could never do with the SPC900 webcam, maybe it’s the Baader Solar Filter paper that made it possible, but I think it was really the DMK21 camera.

I processed them all in Registax 5 and then added some false colour in Fireworks. The distant image was taken with a Skywatcher ED80 Pro and the close-up shots with my 10″ LX200.

Solar Activity 13th March 2010

Writing this blog post from actually inside the observatory today, now I have sorted out my internet access, by using a powerline adaptor which passes the network data through your home electrical wires and is a lot more stable than wireless. especially if you are any distance away from the house.

Did not expect to do any imaging today, just opened the roof to check on the Sun and see if there was any activity, and there was, even better than when I looked a couple of weeks ago.

Here are my images, the enlarged images of the sunspots were taken on my 10″ LX200 with a glass solar filter, using an SPC900¬†webcam and then stacking in registax, one in colour and one in black and white.

The large shot of the Sun below was taken via my Canon 450D SLR using a Televue 2x Barlow on my 80mm refractor with a Mylar paper solar filter.

Small Sun Spots

Today it’s snowing, but yesterday¬†I managed to view the Sun and do some imaging – crazy weather!

Usually when viewing the Sun at the moment it’s a very uninteresting sinle coloured disc, but today (20th February 2010) I was amazed to see two small sunspots on the face of the Sun.

With this being such an unusual occurence lately I had to get some images.

Before I purchased my guidescope I only had solar filters for the LX200, by way of a hartmann mask and a glass ETX solar filter. Now I also have a mylar sheet type filter for my small refractor. Both provide different colours of the Sun.

The ETX glass solar filter gives an orange colour to the Sun, whilst the mylar sheet provides a kind of white colour.

The sunspots are so small you may have trouble seeing them on these images, but they are on the lower right hand corner. Click on the image to enlarge it.

First the mylar image on the refractor:

My Solar Eclipse Photo on ITV Anglia News

My partial solar eclipse photo was also picked up by ITV Anglia News on the evening programme on 1st August 2008.

Thanks to Anglia News for sending me the video, as I missed it on TV.

My photo is the first image (Daniel Coe, Ely).
