Title: The Sun
Post by: Kenny on Mar 01, 2015, 19:30:20
Two images of the Sun from today, separately captured from the mosaics work. Coronado Solarmax 60 solar telescope of HEQ5 mount. Celestron NexImage Solar System Imaging CCD camera with x2 Barlow lens. 60 second AVI in grayscale captured in SharpCap2. Stacked in AutoStakkert2. Sharpened with Wavelets in Registax. Cropped and recoloured in Adobe Photoshop CS2.

Solar swirling
A very large swirling mass on the face of the Sun.

Solar flare (?) and small prominences
It looks to me like there is a 'flare' on the face of the Sun at 2'oclock in the image. It was clearer in the camera and had a 3D effect. There are also very small prominences on the edge - there weren't many on the Sun when I was imaging.

Excellent - they have come out quite nicely with quite a bit of detail!

Also, the colouring has a very natural look to it.

Thanks all. I'm please the quality of these is improving but am definitely stretching the capabilities of the equipment I have access to.

I'm very impressed Kenny, loads of detail and interest.

One thing I've found is you can just keep stretching out those capabilities. Often a little DIY tweaking is required, for instance adjusting the worm gear clearance and a bit of correct lubrication can make the HEQ5 much smoother which leads to shaper images with only a little time and a tube of lithium bike grease spent. Search for Astro-Baby's site and no it won't get you into trouble with the missus!
