The following solar prominence images are submitted by Jim Ferreira, based in California USA. Detailed info is available in the pictures. Besides the remarkable images, Jim also sent us some comments on the camera this time.

Here I quote his email:

Here are a couple photos of recent prominence activity in H-alpha.  Both imaging and observing are done with a Lunt LS50F H-alpha filter fitted to a 102ED refractor.  Visual views, via oculars, through the system are dramatic, however, using the DMK21 or DBK21 as an electronic eyepiece is really where the action is.  Being able to adjust camera gain and gamma while under a dark cloth over the laptop affords splendid views of both prominences and the chromosphere.  For those moments of steady air, just a click of the mouse and you’re recording AVIs to view and process later.  Since acquiring the DMK21, my eyepieces now essentially collect dust.

Many thanks to Jim. Well done!

This is the first GigE astronomy camera’s image published in this blog. The photographer is Jean-Luc Dauvergne. Jean-Luc photographed this picture on the top of Pic du Midi, southern France.

Here is the picture in color, also as NASA’s Astronomy Picture Of the Day on Feb.05:

He also sent us a picture in which he pinpointed several terrestrial features of Mars. You guys all understand them though they are in French.

Jean-Luc told us

took the picture on the T1M of Pic du Midi. It is an infrared image (742nm). The sky was far from perfectly stable.

Merci Jean-Luc!
