August 2018: the great American solar eclipse

On August 21st, 2017 the Moon hided the solar disk in what was known as the great American solar eclipse. The totality run from the west coast, in Oregon, to the east.

With my family we observed this wonderful event from Madras, Oregon. I imaged it with a Canon 70D with a 300mm zoom.

This is the totality, in a HDR composition (HDR combines different exposures so as to gather details of the inner and external corona):

Just before, and after, the totality what is known as the diamond ring appears. Notice the pearls in this picture, a second before the Moon disk hides the Sun:

And this was an amazing final diamond ring:

February 2017: the Horsehead and the Flame nebulae

ok, I admit it. This is one of my favorite targets. The inspiring horsehead. I had imaged it with my 8″ LX200, but I wanted to try with the new setuo, with its bigger FOV.

Here we are, together with the Flame. The bright star is Alnitak, a magnitude 2 beast, which floods the image with its powerful light. This imposes some challenges for the processing tasks.

This image is a cropped version. Original one is even wider. But it seems that my alignment was not quite good that day, and some field rotation is shown in the original one.

January 2017: the Rosette

This is one of the beauties of the winter skies. I confess that, for one or another reason, I hadn’t imaged it before. The fate wanted that in the first ocasion that I’ve tried, a group of thin clouds invaded a transparent sky, and spoiled my session with the beauty.

As a result, this image has much more noise than I wanted. The first subs are very good, but the following ones were damaged by the appearing clouds. I needed all the subs to combine them, as my session had to finish when the sky got totally covered. Well, this encourages me to try again :-)

January 2017: Orion Nebula & the Pleiades

Well, these are easy targets. But I wanted to test my new setup with them , and the night I had free to do so the Moon didn’t allow for a much more complicated objects.

This is the Oriuon Nebula, M42. The large FOV of my setup is great for this object, as it frames the whole nebula and its surroundings.

And now the Pleiades cluster, M45. Also framed pretty well. As you see the faint nebulosity is clearly captured. This is a cropped version:
