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.

This is a cropped version of it:

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

August 2016: North America & Pelican in H-alpha

The Moon was shining powerful, almost full. Time to take a break? Nop! With the H-alpha filter high-quality pictures can be obtained regardless of the moonlight.

So I pointed at the NorthAmerica Nebula, and tried to frame also the Pelican.

It’s amazing how much detail can be achieved with long exposures of the H-alpha filter.

As a curiosity, a satellite happened to cross the field while I was imaging. It was recorded in the first frame:

After some investigation, taking into account the precise timing of the event, I identified the invader as NEE-02 KRYSAOR, launched in 2013 and belonging to Ecuador:
