Picture of the Sun from Singapore

Blogged by Aurélie Le Fort Beunink on July 21, 2011 and tagged with Sample Images, Sun.

The image was taken on 18 July close to sunset. The imaging equipment - DMK 41AU02.AS camera on a single Solarscope SF50 HA filter etalon (0.7A), Borg 76mm achro on an iOptron iEQ45 mount. Post processing was done on Registax 6 and Photoshop. Multi passes with curves and wavelet processing done. I am glad to be able to show both the prominences and disk surface details in one image without having to process both separately and merging them. It will be interesting to see the new emerging sunspot 1257 (at near 5 O'clock position) developing over the next couple of days.

I find the DMK camera very versatile for solar imaging. Thanks for a great product.
