Comet NEOWISE

 

C/2020 F3 (NEOWISE) or Comet NEOWISE is a long period comet with a near-parabolic orbit discovered on March 27, 2020, by astronomers during the NEOWISE mission of the Wide-field Infrared Survey Explorer (WISE) space telescope. At that time, it was an 18th-magnitude object, located 2 AU (300 million km; 190 million mi) away from the Sun and 1.7 AU (250 million km; 160 million mi) away from Earth.[3]

 

By July 2020, it was bright enough to be visible to the naked eye. It is one of the brightest comets in the northern hemisphere since Comet Hale–Bopp in 1997 and was widely observed as being clearly visible with the naked eye. Under dark skies, it can be clearly seen with the naked eye[4] and might remain visible to the naked eye throughout most of July 2020,[5] at least until July 23, the point of the comet's closest approach to Earth. Prior to that date, the comet will be getting closer to Earth as it moves farther away from the Sun. As of July 18, the comet was about magnitude 3.[6] Binoculars are required near urban areas to locate the comet.

Not sure this is my best image of this subject, but I was amazed to get this result from just 3 x 3-minute light frames! I couldn't get any more, as the Earth rotated the nebula behind an obstruction.

Some star-bloating towards the right again, but not as bad as the Veil image.

Manually, off-axis guided for 3 x 3-minute exposures at ISO 1600, f/4. Modified EOS 600D & Revelation 12" Newtonian reflector telescope.

The Pisces Cloud, also known as Arp 331, is a small chain of elliptical galaxies in the constellation Pisces between the Andromeda Galaxy and the Triangulum Galaxy that are roughly around magnitude 13.0 and lower. This group is actually part of the Perseus-Pisces Supercluster. The photo contains many more galaxies than are shown, I have identified just easily identifiable galaxies.

This image is composed of 100 x 15 second images at ISO 3200 with additional dark and bias frames. Tech Info: Meade LX90 12” telescope, Antares Focal Reducer, and Canon 6D camera. Imaging was done on September 1, 2016.

Following comments made by Jean Jacquinot on my last iteration of this thing, a committee meeting was convened, and the man from the frozen north agreed that some detail had been lost. It was decided that a reprocess was in order, and this has now been actioned. Above is the result :)

 

Does Flickr sharpen images when you upload them? It certainly seems to. Anyway, a full reprocess, colour tweaked in places, etc. etc. Better I think. Thanks to Jean for pointing out my previous oversight :)

 

Last iteration here, for comparison.

 

I now regard the horsey in the same light as Andromeda, so I'll say goodbye to it until next year :)

Die Milchstraße, auch Galaxis, ist die Galaxie, in der sich unser Sonnensystem mit der Erde befindet. Entsprechend ihrer Form als flache Scheibe, die aus Milliarden von Sternen besteht, ist die Milchstraße von der Erde aus als bandförmige Aufhellung am Nachthimmel sichtbar, die sich über 360° erstreckt.

This is a view of IC 1795 - The Fish Head Nebula, and is part of a huge star forming system of gas and dust located along the Perseus spiral arm of our Milky Way galaxy. The nebula is located in the constellation Cassiopeia approximately 6000 light-years from the Earth and is adjacent to the much larger Heart Nebula. This image was designed around the Hubble Palette of colors, splitting my image into artificial Sulfur II, Hydrogen Alpha, and Oxygen III channels. The image was then reassembled giving these hues that are typical of images from the HST.

Yet another clear night - whatever next?! :)

 

I did another 4 hours on M33 last night, only to discover at the end that the dew band wasn't working - 4 hours wasted, more or less. Not to be deterred, and with Orion waving at me invitingly, I had a go at good ol' long face. The ED80 works miracles on this, compared to the 200p :)

Right, I'm officially sick to death of Andromeda! This is now 16 hours of varying sub-lengths and ISO settings, and I've reached the point where my skies are going to yield no more. Quite depressing to think that 16 hours here produces the same result as perhaps an hour under dark skies - so this is my final attempt ;) (Wrong!). Better processing than the last shocking effort I think - a little more subtle, and some fainter detail evident (and some detail less evident as the contrast has been turned down a bit!)

 

Having spent a fortnight thinking about very little else, I can now get on with my life :)

[20131205_DARC_II]

Also known as IC 434 and Barnard 33.

The horsehead nebula is approximately 1,375 light years away in the constellation of Orion. A very difficult target to find in a telescope, it's possible with a large aperture using specialist filters. A camera that can pick up Ha it's much easier :-)

IC 434 lies on Orions belt close to the flame nebula with the very bright star Alnitak (just visible lower left) separating them.

Having put a post on my fb page looking for an alternative to DSS, DSS got its revenge. It spat out junk every time I stacked this until, in exasperation, I purchased a copy of Nebulosity. DSS then stopped assing about and gave me a reasonable stack. Spooky.

 

Anyway, this is 28 x 8 minute subs under my light polluted skies, so is a decent result :)

Messier 67 is an open cluster in the constellation Cancer. This open cluster was photographed on March 9, 2015 using ten one-minute exposures using my standard astrophotography setup.

 

The images were "stacked" together using the software package DeepSkyStacker. The final image was edited using Corel PaintshopPro software.

 

The open cluster, at the time of this writing, was located near the planet Jupiter and the Beehive Cluster (Messier 44). At magnitude 6.1, you will need a pair of binoculars to see this ancient open star cluster.

The Fossil Footprint Nebula.

Discovered in 1790 by William Herschel NGC 1491 can be found in the constellation of Perseus at a distance of approximately 11,000 light years from us.

Known as a HII region. This type of nebulae is caused by ultraviolet radiation from the hot young stars being born within ionizing the surrounding nebula, which cause it to glow in visible light allowing us to see it.

Globular Cluster Messier 62 (M62 or NGC 6266) is a cluster that can be found in the constellation of Ophiuchus. This cluster was photographed in July 16, 2015 nd the final image is a stack of 18 thirty second exposures at ISO 3200 using a Canon 6D at prime focus of a Celestron 6" telescope. The imaging system was mounted on an iOptron ZEQ25 equatorial mount. M62 lies at a distance of about 22,500 light-years. Software used to create this image include DeepSkyStacker (for stacking the individual frames), ImagePlus (for initial stretching and post processing), and Corel Paintshop Pro X5 for the final image adjustments.

I finally got a few clear nights to try out the new scope. This is hydrogen alpha data shot over 4 nights from my home observatory. RGB data will hopefully be finished this week.

The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy 21 million light-years (6.4 megaparsecs) away from Earth in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781 and was communicated that year to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries.

On August 24, 2011, a Type Ia supernova, SN 2011fe, was discovered in M101.

Messier 100 (also known as NGC 4321 or the Mirror Galaxy) is a grand design intermediate spiral galaxy in the southern part of the mildly northern Coma Berenices. It is one of the brightest and largest galaxies in the Virgo Cluster and is approximately 55 million light-years from our galaxy, its diameter being 107,000 light years. (ref: Wikipedia) The last time I imaged this galaxy was March 2023 when the dwarf planet Ceres was passing between the Earth and Messier 100 spiral arms.

The California Nebula at 135mm 📷

 

Just 30 x 90-seconds at ISO 800

 

You can't beat capturing a full-color image in an hour (set-up time included!)

 

I love the FOV the Rokinon 135mm provides (thank you again to everyone that recommended it)!

 

This was a quick setup when the clouds parted for 2 brief hours last week (snowing now). I spent longer processing the image than acquiring it 😆
