Sunspots and Big Prominences, SE Solar Limb (28 July 2012)

[David_Evans]

Good weather in the UK today

A bright sunny morning with very few clouds and a nice blue sky.

There is a lot of activity towards the south-east solar limb.... Four large single spots, three big prominences and a filament!

Here is an image that I captured at 08:51UT with my 60mm SolarMax Filter / 30mm Blocking Filter, 80mm Vixen F11.4 and DMK31AU03.AS camera.

Although cloud is now on the increase in central England (50% at 12:46UT) there is still plenty of opportunity for more imaging.

If the air remains stable I'll try a 2.5x PowerMate on the proms.

Regards,

Dave

Fantastic image Dave, so crisp and the spots/proms look stunning.

Thanks for sharing

How have you got a white background? Thats a lovely image.

Thanks for posting the heads up, it made me go out and get the scope out.

What a fantastic solar image. I have been looking at these proms and they are very impressive. Once again brilliant image.

Thanks Ken and Ant.

The light background is applied during the processing stage. I use the 'replace colour' procedure in Photoshop Elements.

Thanks Mark,

I've just used a 2.5x PowerMate to image the proms... The atmosphere is very turbulent at the moment... If successful I'll upload the photo in a short while.

Nice results, nice presentation.....well done!

I like the coloured negative finish you've used. It brings out the fine detail very well

Ah is that how he did it. Thanks Kev

nice capture, the background in white adds a new perspective to solar images

Great photo Dave,

I re-processed mine from yesterday and it is looking a lot better, but didn't have time to finish it yesterday and I am out today, so will try and post later. The white background really works well.

[David_Evans]

Thanks guys.

We've had a lot of good weather in the UK over the past week. Quite steady atmosphere too..., great for solar imaging. I hope to add more photo's soon.

Hi,

I re-processed my image with x2 drizzle, which brought out a bit more surface detail. During the combining it lost a bit of the prom detail, but overall about as good as I can get at the moment.

[David_Evans]

Very nice DrRobin.

What image capture program and stacking software do you use?

I'm using IC-Capture and Registax-6.

Hi Dave,

I used IC capture and Registax 5. I haven't had much luck with Reg 6 on solar images, but perhaps it would like the output of my DMK better? I did try AS2!, but couldn't really get used to it. I haven't tried AVIStack yet and now don't have enough time before going on hols. I will give it a beeter go when I am back.

Hi,

I captured one video of the surface and stacked it using Reg 6, it seemed to work okay and I think it has done a better job. I noticed that when my videos were of good quality (greater than 95% selected) Reg 6 seems to work but if they are bit lower quality it seems to stuggle and doesn't stack correctly.

Anyway here the pic in both monochrome and with colour added. Looks like it is slighty over exposed in the top right hand corner, that I have over done it with the wavelets? I am still trying to find my way with this.

[DrRobin]

Hi,

I reprocessed the surface detail from the combined picture in Reg6 and Reg5. Reg6 seems to make a better job of the stacking, but I have over-done it on the Wavelets. Reg6 and Reg5 images attached.

Great images. H-alpha pictures are always so beautiful. Rather surprised about the difference between registax versions. It mostly seems to be contrast though there seems to be some more details in the reg6 image.

[DrRobin]

Thanks htm,

I have over done the Reg6 images at the Wavelets stage. I am going to give it another go and turn down the settings. If it is any better I will post.

[DrRobin]

Hi,

Restacked in Reg6 with the Reg5 version for comparison. The Reg6 (left) version shows more detail and contrast.
