DESCRIPTION:

Between a cloud and another I finally got it: the comet 45P/Honda-Mrkos-Pajduáková after the perihelion. This photo was taken in Sicily on the night between 8-9 February 2017. The comet, during the shot, was distant about 0,93 AU from the Sun. It, as expected, exhibits only a coma and not a tail.

IC2177 Seagull Nebula. This nebula is near Sirius and Sirius is the brightest star in the night sky, not to be confused with planets, Sirius is near the Orion constellation.

 

It's amazing when you look up in the night sky and see nothing with your naked eye, however, given the right exposures and magnification you can see what's out there.

 

This image was captured during the last new moon in January/2017. Taken with a Mono Camera, the details are:

15 - Ha Filter

15 - SII Filter

15 - O3 Filter

45 Total Exposures @ 15 Minutes each...or 11.25 Hours of Total

Exposure time over two nights. Using a 80MM Telescope.

 

Another interesting note about the Seagull Nebula, the "Bow Shock" (Right Center) over a large star. This happens with the nebula (Plasma) interacts with the magnetic field of the star. Kind of like the solar wind from the star interacting with the nebula gas. A rather unique occurrence since most objects are so distance from one another.

This deep image shows the rarely seen full extent of the intricate shells and faint outer ionised gas envelope around NGC 3132. At only about 1.5' X 1' in size, this was a real test for my scope and the local seeing conditions!

Orion-orama

(Barnard’s Loop. M78, B33, IC434, NGC2024, NGC1977, M42 & M43)

Here with this 3 panel Mosaic are the most popular Jewels of The Constellation of Orion all captured from the backyard of my new home on the slopes of Grand Mesa at an elevation of 6600 feet in Western Colorado over only 2 nights.

 

I am amazed with the sensitivity and low read noise of the new QHY367C, Full Frame 7376x4938, 36.4mega pixel One Shot Color CMOS camera. The mosaic comprises of 135 x 2 minute exposures for a Total Integration time of 4.5 Hours.
