I found an empty piece of plastic the other day, on which I had no hesitation in slapping a modded Canon 500D, purchased at a very reasonable price from James Stannard here. There then followed a bit of a learning curve - having been used to a Nikon - which has taken up the best part of two weeks. But I got there in the end :)

This is another collaboration with my good friend Dave Williams from the northern wastelands, who generously donated large portions of Ha, used as luminance.

I will now spend some time trying to breathe life into my Nikon D70 so that I can inflict some considerable pain on the thing, before I eventually kill it - slowly.... :)

This is one of the most beautiful and distinctive nebulae in our galactic neighbourhood.

The eye-catching Bubble Nebula is designated as NGC 7635, Sharpless 162 and Caldwell 11 and lies close to the direction of the open cluster Messier 52.

It is 7 light-years across – about 1.5 times the distance from our Sun to its nearest star, Alpha Centauri and resides 7100 light years from Earth in north-western Cassiopeia close to the border with Cepheus.

The 8.7 magnitude seething star forming this nebula (BD+60°2522) is 45 times more massive than our Sun. Gas on the star gets so hot that it escapes away into space as a stellar wind moving at almost 7 million km/h.

As the surface of the bubble's shell expands outward, it collides with dense regions of cold gas on one side of the bubble. This asymmetry makes the star appear dramatically off-center from the bubble, with its location in the 10 o'clock position in this image.

NOTE: This is a pseudo-narrowband image. I tried with post-processing to give the impression of using Ha, OIII and SII filters. The original version shows only red nebulosity (hudrogen). It was really a persistent and painful struggle in Photoshop :)

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!

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!

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.

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.

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.

We had several clear nights on the bounce a week or two back, and I spent the time imaging this thing as Cygnus was still getting up above my house a little late. This is just short of 10 hours, but I put it away because I got the feeling it was out of focus when comparing it with the version I did back in 2011 with the 200p. The stars in the cluster don't look quite as tight as I think they should.

Whaddya reckon? Out of focus?
