Photographing the Milky Way is my Muse. I keep going back to it seeing if I can approach it from another perspective. It's intensely beautiful. If you've never seen it, then you owe yourself an opportunity to go away from the city or town and out to a rural area. Even a 20 minute drive outside of the city limits will take you to a dark enough sky to see the general shape of the bright Cygnus region. This was taken the morning of August 12 during the recent Perseid meteor shower.
A view of the Andromeda Galaxy in the constellation of the same name captured in a stack of ninety-one images that were exposed for 10 seconds each using a hand-driven, barn-door type tracking mount (two boards, a hinge, and a screw you turn by hand). This photo also shows Andromeda's two satellite galaxies, M32 and M110 (see image notes for the locations, M110 is the small elliptical galaxy slightly below center).

I caught a news story a few days ago about a supernova in galaxy NGC 3184 and decided to try and image it on March 29, 2016. Problem was the high winds here in Pennsylvania. The magnitude was listed in the 15 range, but decided to try imaging it using my Canon EF 400mm f/5.6L USM lens.
The wide field image (see my other Flickr post or my blog) is a clip from a full frame, stacked 14-minute total exposure using a Canon 6D and Canon EF 400mm f/5.6L USM lens mounted on an iOptron ZEQ25 mount. 14 x 60 seconds at ISO 3200, stacked in DeepSkyStacker and further processed in Adobe Lightroom and ImagesPlus.
I then clipped the galaxy from the full frame view and processed it in Lightroom. I found a great pre-supernova (baseline) image by Adam Block (who gave me permission to use his image for comparison purposes – thank you Adam). Adam’s image can be found at www.caelumobservatory.com/obs/n3184.html
I hope to do additional imaging as time permits.

I had to try it. Not an amazing image, but I'm happy with it considering the short focal length.

I processed with 3x drizzle in DeepSkyStacker, but I don't think it made much of a difference; I think my tracking accuracy limits the amount of detail I can achieve on tiny objects with my setup, and possible my sensor. Even though it's tiny, this is still a fairly big crop.
I plan to shoot M 101 next time - my attempt a year ago was marred by windy conditions. I probably won't bother with 3x drizzle, but might still apply 2x drizzle.
Having just ordered an Olll filter, this will eventually be my first bi-colour image with Ha and Olll, hopefully. This is about half of the Ha, just 6 x 1200 seconds @ iso1600 with the cooled mono 450D - I'll have to add some more as this is quite noisy.
My mount has been serviced and now appears to be doing its thing as it should. I'll now wait for the next disaster to befall me, as is the nature of this stuff :)

Like the Horsehead Nebula, this is my third go-around for the Orion Nebula. The first time I imaged the Orion Nebula was back in 2008 with a Rebel XT DSLR camera. For this picture, a series of short and long exposures were required to see all aspects of the nebula.

Same ol' same ol' :)
I uploaded a version of this a month or so back that was supposed to be a combination of this year's data and last year's. Turned out it wasn't - what I got out of DSS was exactly last years data - it completely ignored this year's. DSS playing silly buggers.
This, on the other hand, is the combined data - 2 hours 23 minutes of 60 second subs. This is about three quarter frame, and rotated to provide a different angle - change is as good as a rest. Nice and small and cute :)

I was browsing through some old captures, and then find this one. Why did I forget to publish it?
I don't know! Well, better later than never.
This was my first capture using my T6i, back on July 9, 2020.
I remember now, why I did capture the Crux again. My hope was to compare, side by side, my old Nikon D5000 and the "new" Canon T6i. Well, my D5000 served me well for a long time, but now it needs to retire. :)

The Crux constellation and the Coalsack Nebula (C99) captured with an old DSLR.
My Nikon D5000 have a serious issue with its sensor. On the right corner and top of the image we can see it failure. A region of the sensor which does have a lack of sensitivity.
First I though it was a "flat frame issue", but it's not. Darks and bias doesn't help.
Only after a carefully processing I'm "ok" in posting this picture. But my Nikon D5000 is old, and I'm not happy to say that it needs to retire.
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 :)

It’s nearly four months since I captured this. Where did that time go? Imaged back on the 21st of August, this shot of the Milky Way’s galactic core region includes quite a few interesting features.
The “Dark Horse” nebula is one of the most prominent parts of the shot, although down here in the Southern Hemisphere it’s more often known as the “Galactic Kiwi” due to its resemblance to the national bird of New Zealand. Grouped down at the bottom of the frame is the bright orange supergiant star Antares, with Mars to the lower right of that and Saturn across further to the right. In the same area as Antares is the Rho Ophiuchi cloud complex, a star-forming region of space. You can see some of the yellow and blue gas clouds in the photo.
Like most Milky Way fanatics I’m missing this part of the sky since it’s obscured by the sun at this time. In a few more months it will be back again and us addicts will get our longed-for fix.
This is a stacked image created from 13 “light" shots of the same region, 7 “dark" shots at the same settings as the original but with the lens cap on, plus 12 “bias” frames. Stacking reduces the digital noise of the overall image and helps to bring out a bit more detail than a single shot would. The 13 frames were captured with Canon EOS 6D, Canon 50mm @ f/2.8, 6 sec @ ISO 6400.

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!
