Sky this Week

Checkout the interactive solarmap at my other website. You may now select a date from Jan 2, 1996 to present and see what regions were visible on the Sun on that date. (Note that the Drupal date popup module that I used annoyingly requires that you actually click on date rather than just typing it in). For example select June 1, 2000 and you’ll see quite a few more regions listed than you do now at solar minimum.

Sun from around 11 am in h-alpha. A couple nice prominences visible on NW and SW limb. Its been a long while since I’ve done h-alpha. I seem to forgotten most of the processing required. Nonetheless here it is. Solarscope halpha scope and DMK21AF04.AS video camera. Aligned and stacked with Registax5, compositted and false colored in Photoshop.

Image of Jupiter at 5:09 am (11:09 UT) this morning. Good conditions for a change, clear sky, no wind, transparency very good, and turbulence around 6/10. Used the Phillips Toucam 840k at cassegrain focus of Celestron Nexstar 11. Image oriented north up, east left (more or less). Aligned and stacked 80% of 1400 frames, wavelet sharpened (26-16-1-1-1-1) using Registax5, color adjusted, resized, cropped with Photoshop.
