Another quick test of my new Skywatcher Star Adventurer Mini tracking mount, this time shooting the Milky Way. It was cold and very windy, my polar alignment was not very accurate and I didn't frame the shot as well as I could have, but for a test shot I'm fairly happy with the result.

This is 5 x 2 minute exposures with my 6D and the old 35mm f/2 lens at f/3.5 and 1600 iso. Stacked using DeepSkyStacker and processed with LR5.

- www.kevin-palmer.com - I'm still sorting through pictures from the Geminid meteor shower, but I wanted to post this picture from early this morning. Comet 46P/Wirtanen flew by the Pleiades in the constellation Taurus. Also known as the Seven Sisters, this star cluster is one of the closest to Earth at a distance of about 444 light years away. The extra hot and luminous stars cast their light on the nearby reflection nebula, which gives it the blue color. Comet 46P/Wirtanen was at it's closest approach just 7.2 million miles (11.5 million km) away from Earth. This makes it one of the top 10 closest comet encounters of the Space Age. While they look the same size in this image, the comet is quite a bit fainter, just barely detectable to the naked eye. The nucleus of the comet is less than 1 mile wide, but it's diffuse coma (cometary atmosphere) is larger than the planet Jupiter.

 

This image was shot with a Nikon 180mm f2.8 lens on a Nikon D750. It is a stack of 8 2.5 minute exposures, along with 4 dark and bias frames. An iOptron Skytracker was used to track the stars. I'm going to need a new tracker soon though. After shooting images for 1 hour, I had to delete 2/3 of them due to tracking errors.

Ermita de Sta María de Melque

This small church is located in a zone relatively isolated from Madrid. I find it an interesting location for night photography because light pollution is not very high. The only negative I find about this place, IMHO, is the fence around the church, as it affects the charm of the place a little.

 

This is my first serious attempt at long exposures of the sky with a star tracker (Skywatcher star adventurer). The sky is a stack from 11 exposures of 60 seconds at ISO 800, stacked with DeepSkyStacker.

 

The foreground was shot with a Nikon D850 and Samyang 24 1.4 at F2- 20 seconds at ISO 4000

This is NGC 7380 The Wizard Nebula in Cepheus, and I imaged this on Christmas Eve and Christmas Day as it was clear and I'm a sad bugger. :)

 

Quite small for my setup, and very difficult to process, this is 67 x 300 second subs for just over 5 and a half hours. Looks much better in the Hubble Palette, but I can't do that! :)

 

Happy New Year guys :)

First night with my new mount (HEQ5) and it was almost perfect clear sky with no moon!

Also it's the first time I've managed to make the guiding work properly, made all the lights 300sec long and only rejected the ones with clouds :D

 

As you can see, I'm really rusted with processing the images. It's the 3rd image I've processed since February! Noise got out of control, colors could take a better aproach, not happy with the stars....so many things poorly done but I know I will process it again at some point.

We had another good astronomy session at Wivenhoe Hill west of Brisbane last night. I spent most of the time doing visual observing with my brother-in-law's 14" Dobsonian telescope, but I also had time for a couple of Milky Way panoramas.

 

This one is a panorama of the central section of the Milky Way galaxy, taken with a 35mm lens and the Star Adventurer Mini tracking mount. Each panel consisted of 5 x 120 second exposures at f/3.5 and 1600 iso, stacked using DeepSkyStacker. Panorama stitching was done using Microsoft ICE.

Febrero 2022 - Punta Indio - Bortle 3

Oh my... I really love this one. The Flame Nebula (NGC 2024) is the central orange component in the image and the bright star is Alnitak, the leftmost star in Orion's belt. And the craziest part (to me) is that this is just an RGB image... this is what's actually there with a normal exposure, colors and all! I used about 3 hours of Red, Green, and Blue data... from individual 3-minute exposures stacked in DeepSkyStacker and combined in PixInsight.

 

I shot this on Monday morning for the hours after midnight when Orion was higher in the sky and above the neighbor's trees. In addition to the Flame Nebula, the red trailing off at the bottom is part of the Horsehead Nebula and there are a few small other nebulae that you can see around the frame. We're wrapping up a tiny sequence of clearer nights right now, so I hope to have some more brand new telescope-shots to share with you soon!

The Hyades star cluster is the head of the bull in the Taurus constellation; Aldebaran, the brightest yellow star, is the eye. Quite a few dark nebulae are also present in this extent, as well as star cluster NGC 1647 in the upper left.

 

I normally wouldn't have astrophotographed on a night forecast to have only a small window of clear skies, but it had been a couple months since I had been able to image, so I went for it. I only managed 20 minutes of data without high, thin cloud cover despite shooting for well over an hour, but you have to take what you can get during winter in north Idaho. I'm going to shoot this one again sometime.

I stacked about an hour worth of data in DeepSkyStacker and edited the TIFF in Photoshop 2020 and Adobe Camera RAW. :) (y)

Now this is a bit of a hotchpotch of data: Some very old data from the D70 back in the day (for the core), some data from the Canon/ED80/EQ5 and some recent data from the new setup. And some Ha data from my buddy Dave Williams for the outer faint bits.

 

All thrown into the pot and shaken (not stirred) until, as if by magic, this came out the other end. Good fun....:)

Hi all,

 

This is my longest astrophotography project to date.

 

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.

 

It constitutes the visible portions of the Cygnus Loop, a many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun, which exploded around 8,000 years ago. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full Moon). The distance to the nebula is not precisely known, but Far Ultraviolet Spectroscopic Explorer (FUSE) data supports a distance of about 1,470 light years.

Lots of processing going on here, including stacking of 10 lights with 5 darks in DeepSkyStacker, with further adjustments in Lightroom. Each exposure 20s / F2.8 / ISO1600

 

Sadly I forgot to switch off SteadyShot and so some blurring of the foreground occurs!

Inspired by Erik's recent image, and being bored after being clouded out for what seems like decades, I thought I'd faff about :)

 

A starless version of my recent collaboration with Dave Williams. I've left IC 431 and 434 in there because they are nebulae after all. I've also left in Alnitak and his buddy as I'm not good enough to take them out :)

 

I won't submit this to astrometry, as it may struggle :)

 

After my first test shot with little exposure time under rather unfavourable conditions already hinted at the famous Horsehead nebula, I tried this again, this time for real. A wonderfully clear night, no moon, and only one target...

 

I was able to acquire 2 h 8 min in 256 useful subs before my camera's batteries ran out and I got cold...

But I was amply rewarded! This image taken at 300 mm focal length with the TAIR-3S just exactly fits all the famous objects, from the Flame nebula (bottom left) to Orion's bright belt star Alnitak, and of course the Horsehead nebula, to the Running Man nebula and the Great Orion nebula M42 on the top right. I also like the soft but numerous spikes from the slightly stopped-down lens on the brighter stars.

Maybe I'll find some time to compose a HDR image some time, where the core of M42 isn't burnt out and the Trapezium stars are visible, but seeing has to be quite good for this and M42 season is nearing its end here...

First astro session of 2021, and a fairly predictable subject at this time of year! Having said that, I've not imaged M42 with the 12" Newtonian 'scope for several years.

I didn't take many sub-exposures, but instead a small number each at settings between 5-seconds and 2-minutes, ISO 3200, to preserve detail in the bright inner and faint outer regions of the nebula. I stacked each set in DeepSkyStacker software and then combined them as layers.

Additional post-processing: minor curves adjustment in Canon Photo Professional; noise reduction and colour gradient correction in CyberLink PhotoDirector.

I’ll be honest, I really never viewed Polaris under any magnification before. I’ve always used it as a guidepost to align a telescope or other piece of astronomical equipment. While recently setting up my pier and Meade telescope for the first trial runs, I focused the scope on Polaris to begin alignment, and snapped a few quick pictures. That is when I noticed a little companion star right next to it! Low and behold, Polaris is a multiple star system with an 8.7 magnitude companion (see image in the two o’clock position). Polaris actually has another, closer star, designated Polaris Ab that amatuer scopes can’t resolve. You can see a Hubble view of this star at:

These "clouds" are a star-forming region referred to as the Bubble Nebula, or NGC 7635. In the middle of this cloud, there's a hot young star creating some significant solar wind that is blowing out a spherical section, leaving behind something that looks a bit like a bubble. The whole formation is a little over 7,000 light-years away in the direction of Cassiopeia.

I often use narrowband imaging for my astrophotography, but I shot this one in pure RGB, so this is exactly what both the eye would see if it could gather in enough light. And this is exactly what a normal full-color camera would show if I did a similar exposure with it. BUT... I only have a monochromatic astrophotography camera, so this came from separate exposures in red, green, and blue.

Here is an image I grabbed on the evening of December 27, 2016, it is called the Skull Nebula (NGC 246) and is a planetary nebula found in the constellation Cetus. It has a magnitude of around 8 with a 11.8 magnitude central white dwarf star. This planetary nebula is about 1,600 light-years distant.

Tech Specs: This image is composed of 120 x 15 second images at ISO 5,000 with 5 x 15 second darks and 5 x 1/4000 second bias frames using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Imaging was done on December 27, 2016 from Weatherly, Pennsylvania.

7 shots at ISO3200, f/3.5, 10mm, 30" stacked in DeepSkyStacker with dark and bias frames subtracted.

 

The strange orange/blue/green glow is actually the Zodiacal light on the horizon - very hard to see typically!!

This is a stack of 9 exposures, i.e. 15 minutes in total plus 13 dark-frames. The camera (Sony ILCE7) and the 200mm lens (Canon EF 70-200mm 1:4L) have been attached to a "Star Adventurer"-mount in order to compensate for earth rotation, while shooting at F4.0/ISO 1600. Stacking has been done with DeepSkyStacker, and final editing with Photoshop CC 2015.5. Place of observation was close to Bremen, in the northern part of Germany.

Here is Comet 29P/Schwassmann-Wachmann from December 14, 2022.

 

Tech Specs: Meade 12” LX-90, Antares Focal Reducer, ZWO AS071 running at -10C, Celestron CGEM-DX mount, ZWO ASIAir Plus, ZWO EAF, 60 x 60 second exposures, darks from the library and flats after the imaging session, DeepSkyStacker and Tycho Tracker. Image Date: December 14, 2022. Location: The Dark Side Observatory (W59), Weatherly, PA, USA (Bortle Class 4).

An unguided, short exposure picture of the Cigar Galaxy (M82) created by stacking 33 45 second light frames and 9 dark frames taken by a ZWOASI183MC camera on an Explore Scientific 102ED refracting telescope processed using DeepSkyStacker, Gimp, and Lightroom.

 

This is a pair of interacting galaxies in the constellation Andromeda designated as NGC 169 and IC 1559. Halton Arp divided his “Atlas of Peculiar Galaxies” into groups based on purely morphological criteria. The pair of galaxies here received the designation Arp 282 as a pair of interacting galaxies. The two galaxies are just above the 6th magnitude star HIP2926 (the ring and diffraction spikes are from the long exposure and processing). You can view a Hubble Telescope image of this pair at:
