What a night for testing my new Star Adventurer! 😍

It took me a long time of waiting but finally I got my dream gear, a star tracker!

So, after years of no guided astrophotography... Let the star adventures begin!

And what a good way to start with these two sisters!

So happy for this result, can't wait for next clear sky night!

The North American Nebula next to the bright star Deneb in Cygnus taken with a hydrogen alpha astro modified Canon 5D MKII dslr camera using a Rokinon 135mm f/2 telephoto lens. 30 one minute images were combined to create the picture using DeepSkyStacker, Adobe Lightroom, and Gimp.

 

Veil nebula

 

The Veil Nebula complex is huge, covering about 7 moon widths on the sky, so I can’t get it all into one image. This image shows NGC6960 (sometimes called “The Witch’s Broom”), Pickering’s triangle, and NGC6979. All of these objects are part of a supernova remnant.

The supernova that created the Veil Nebula happened between 5000-8000 years ago and the nebula has been expanding ever since. The glowing gas is mostly hydrogen and sulphur (red) and oxygen (teal) whose atoms are being excited by the pressure waves created by the massive supernova explosion. The progenitor star whose explosion created this object was about 1,470 light years away.

Took the same image data I used for the full Orion's Sword image and reprocessed it with an AOI around the Orion Nebula, applying a 3x drizzle. Came out pretty well I think! The star trailing is more apparent at this zoom level, but still tolerable. The drizzle algorithm also successfully enhanced edge detail compared to just zooming in a bunch on the larger image.

 

The main difference of processing it this way was being able to more finely tune the luminance curve and color treatment for this object/region in particular, as not only did I not have to worry about the other regions of the image, but I could also see the fine detail much better!

 

Interestingly, this image is not particularly inferior to the one I got through a telescope recently. It is much better in some ways in fact!

More processing: stacked 19 shots using DeepSkyStacker, built a model for background light (dusk sky glow) and subtracted it from the image. Now the tail can be traced significantly further. The feature perpendicular to the tail on the right is an artifact (glow from a street light).

My Sony A7S was recently defiltrated and I wanted to test it on a classic object from the night sky, the Orion constellation. I have three lenses (Samyang F1.4/24mm, Zeiss Loxia 2/50mm, Samyang F2/135mm) for astrophotography. I use iOptron SkyTracker Pro but I do not know enough how to do polar alignment so I limit myself to 10s subs for 135mm lens. Here is the result with only 4 min exposure.

We can easily recognize :

- The Orion Nebula (M42)

- The Horshead Nebula (Barnard 33)

- The Flame Nebula (NGC2024)

But the exposure is too short to see the Barnard's Loop (Sh 2-276) (bottom right) and the Witch Head Nebula (IC2118) (top left).

 

Different edits/colorings trying to see which way I liked the look more.

Well heavens above - two clear nights on the bounce. I'd forgotten how to do this stuff ;)

 

My first guided image! :) The Crescent Nebula in Cygnus, a mere 5K light years away.

 

Bought a modded Quickcam Pro4000, with the adaptor to fit it to the SW 9x50 finder scope, from Badgers/Anton on SGL. Then did the EQ5 handset mod using the kit from Shoestring Astronomy, downloaded PHD and voila. Total cost £90 - can't be bad :) Not perfect of course, but then it was never going to be with an EQ5 and rubbish motors. There was some evidence of wispy bits around this, but it looked more like discolouration, so I took it out - probably expecting too much :)

I used the software DeepSkyStacker in order to superimpose 30 standard photos + 10 darks + 10 offsets.

On one hand , we can see that the noise has been decreasing and the contrast is higher but on the other hand the star trails have increased and only the center is sharp :-/

That is a black point of this software.

A simple but effective monochrome shot in hydrogen alpha light. The Cone nebula in Monoceros - very near the more well known Rosette nebula.

I love all the ripples and folds in the thick dusty nebulosity in this object, and think its quite adequate as a mono image by itself, and might not even go back for the additional data.. :)

Had to try it again! Much happier with the lower noise, better cloud detail and overall sharper image. But having 3x as much light will do that for you.

I gave Thor's Helmet (NGC 2359) a shot last year, but this time around I was able to get some more well-rounded data across the various narrowband wavelengths. While this nebula emits primarily in Oxygen-iii, it still has some Hydrogen-alpha and Sulfur-ii data emissions that I was able to more appropriately include (to some degree this time).

 

This nebula's path across my night sky has it only going above the trees for a brief window (a few hours) on a given night, so this image came from two nights toward the end of December. Each exposure was three minutes long, and I was able to get about 2.5 hours of time on both nights. Individual exposures were stacked in DeepSkyStacker and then the wavelengths were aligned and mapped to the Hubble palette in PixInsight before doing my final tweaks to taste in Lightroom.

Clustermania :)

 

A three hour gap in the endless, persistent cloud cover gave me just enough time to do another one of these things. Nebulous stuff takes several sessions under my light polluted skies, and would take months with the weather being as it is, so clusters beckon.

 

This is M38, aka NGC 1912, aka The Starfish Cluster (don't ask me why), and to the right is NGC 1907. M38 is about 4,200 light years away and is about 25 light years in diameter, similar to that of its more distant neighbour M37. It is about 220 million years old. NGC 1907 is around 4,500 light years from Earth. It contains around 30 stars according to Wiki (looks like more to me) and is over 500 million years old.

 

This is a closer crop than my previous two cluster efforts, for two reasons: first, the framing was rubbish, and second, the stars at the edges reminded me just how much I need a field flattener!

 

I'm running out of double clusters to do :)

This is a total of 11 RAW files that represent a total of 6 minutes of integrated exposure time. The Pentax K-5ii was set at ISO 800 for all exposures and these are camera-on-tripod subs, "guided" only by the Pentax O-GPS1 unit stuck in the hot shoe, which moves the camera's sensor to compensate for the turning of the earth. The longest sub-exposure was 45 seconds.

I added another night of data onto my previous image of IC434. A little more lights helped with the general smoothness of the image. Setup and take down of my equipment multiple nights in a row will result in slightly different field of views which can make it difficult to align when stacking multiple imaging sessions.. luckily DeepSkyStacker could handle it easily with no hiccups. It took many hours in the freezing cold to capture this, layered up on lots of clothes to battle the outside temperature, 3 pairs of socks, 2 pairs of longjohns, 2 sweaters and goosedown jacket, toque, gloves, a thermos full of hot tea, but I still had to walk around the park a few times just to get feeling back in my toes.. And this is barely winter weather compared to the rest of Canada, Being the wet climate here though, the moisture seems to chill you right to the bone even when it is only a few degrees below freezing.
