M97 and M108 – Owl Nebula and Surfboard Galaxy in LRGB

M97 and M108

The Owl Nebula (also known as Messier 97, M97 or NGC 3587) is a planetary nebula located approximately 2,030 light years away in the constellation Ursa Major.  It was discovered by French astronomer Pierre Méchain on February 16, 1781

Messier 108 (also known as NGC 3556) is a barred spiral galaxy in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781 or 1782. From the perspective of the Earth, this galaxy is seen almost edge-on.

The image consists of the following
23x180S – Red

25x180S – Luminance

25 Darks, 25 Flats and 25 BIAS frames have also been applied

Leo Triplet of Galaxies

Leo Triplet In LRGB (above) and LRGB+HA (below)

The Leo Triplet consists of three galaxies at a distance of around 35 million light years, M65 (top right), M66 (bottom right) and NGC3628 (left).  I have always aimed at imaging the triplet since I started imaging but never got around to it.

M65 (NGC 3623) and M66 (NGC 3627) are classed as intermiediate spiral galaxies and NGC3628 is also known as the Hamburger Galaxy or Sarah’s Galaxy and is classed as an Unbarred Spiral Galaxy.

The image consists of:-
29x300S of Luminance
14x300S Red, Green and Blue
15x600S of 7nm HA in the LRGB+HA Image
25 Darks and flats subtracted from all frames

In my opinion, there’s only a subtle difference between the LRGB and LRGBHA images, personally I preffer the LRGB Version, the data was captured over multiple nights since the beginning of 2017 but in total gives 5.91 Hours on the LRGB Image and 8.41 Hours for the LRGB+HA Image

NGC2264 – Cone Nebula in SHO Narrowband

My latest image, I feel like I need more SII and OIII Data though to be perfectly honest, I captured quite a lot of dust even with narrowband mainly due to the high amount of HA frames I suspect, well here it is

M81 and M82 Galaxies in LRGB+HA

By far my biggest challenging project to date, maybe not by image acquisition, but by processing.  The above two galaxies caused me lots of grief when trying to process, they just did not come out right with my normal method of processing, so I turned to PixInsight to process them, and I anm so glad I did, the whole learning curve put me back to almost the same level I was at in 2008, but the steep learning curve paid off

M81 and M82 Galaxies in Ursa Major

The images were taken over a number of nights since the beginning of december and totals 12.5 Hours of exposure time

M45 – Pleiades 15mpx Image

I finally got round to creating my first mosaic, and no better target than M45 Pleiades Cluster.  Since my Field of View on the 8″ Quattro would not allow me to get the whole cluster in, I opted to do two images and use a tool called Image Composite Editor to stick together the two mosaic panels.

The Pleiades cluster is also referred to as the Seven Sisters and it located in the constellation Taurus.

The Image consists of
14x300S LRGB for Pane 1 and 2, so in total 9.3 Hours worth of exposure time

25 Darks and 25 Flats

Equipment Used:
Mount: Sky-Watcher EQ8 Pro
Imaging Scope: Sky-Watcher Quattro 8-CF @ F4

You can see on the left of the image that there is a feint blue dount, this is common with reflectors with extremely bright stars and is probably caused by 25 Tau/Alcyone Star which has an absolute magnitude of -2.61 or a regular magnitude of 2.85 which makes it the brightest star in the M45 cluster

M33 – Triangulum Galaxy

My first galaxy with the F4 Quattro, M33 – Triangulum Galaxy.  The galaxy is located approximately 3 million light years away in the constellation of Triangulum, it is the third largest member in a cluster of galaxies which includes our own and the famous M31 Andromeda Galaxy

The image was the first taken with my Nichrome wire in front of the Mirror Fan to prevent dew forming on the Primary…..And it worked!!!

How Fitting for Halloween……My latest image – NGC6960 – Witch’s Broom in Hubble Palette Narrowband

Commonly referred to as the Witch’s Broom or the Western Veil of the larger Veil Nebula, this lies approximately 1470 Light years away.

In my opinion this is not an easy subject to image, and even more difficult to process, the image details are as follows:

15x600S in 7nm HA
15x600S in 7nm SII
15x600S in 7nm OIII
