English: Trifid Nebula (Messier 20 NGC 6514)
Triffid means "divided into three lobes" a name proposed by John Herschel.
It is a nebula of both emission and reflection, and of absorption at the same time, it has an apparent brightness of 6.3
It's 5,200 light-years away from us.

Decided to try out my new Pentax O-GPS1. This was shot using the astrotracer function of the GPS. By the 6th exposure, the clouds started to cover the night sky and got to end the session. Using only 5 exposure of 1 minute, this is the result I get after stacking.

The Orion Nebula and De Mairan's Nebula, M42 and M43 respectively, as viewed under urban light using an Astronomik CLS Clip-Filter. The CLS (City Light Suppression) is an interference filter that blocks the light of the spectral lines of mercury and sodium-vapor lamps and lets the largest part of the visible light and H-alpha emissions pass. All the important emission lines, as well as the spectral region that the very well dark adapted eye can see, can pass through the filter. This was my first attempt at using the filter and stacking images using DeepSkyStacker. Camera used was a Canon EOS 70D, with an EF 24-105 mm lens, mounted on an iOptron SkyTracker. Location was Burlington, Ontario, 43°19'57" N, 79°46'38"W, ambient temperature a balmy -13°C under a waxing gibbous moon, no cloud cover and marginal to average transparency and seeing. Eight light frames and six dark frames, no flat or bias frames, all shot at ISO 400, f/4 for 30 seconds and 105 mm.

Designated NGC 2264, this is in the Monoceros Constellation (Unicorn), 2600 light-years away. If you angle your head 45 degrees to the right, you can see where it gets its name. The Cone Nebula by the way is that pointy finger looking thing about 2 o'clock from centre a third of the way down the image. Not greatly detailed, but I wouldn't expect it to be for such a short exposure! :)
Taken at the same time (shortly before actually) as the Leo Triplet I uploaded yesterday, it was beset with the same problems. I took 80 60sec subs and, because the mount was being a pig (no disrespect to pigs), I could only use 36 of them - so this is 36 minutes. I've never pointed my kit at an area of sky with so much red stuff before (that's Hydrogen Alpha, Hα for short), so I'm kinda pleased with this. Horrendous coma, but that's a "feature" of the kit, and I can't afford a coma corrector, so I have to put up with it. :)
Might have another go at processing later - this was a bit of a rush job to see what I had. The darks problem I had last night is now fixed - DSS being temperamental!

After I have spent hours to watch the starry sky, I tried to realize a image of our nearest neighbor galaxy : Andromeda M31.
Wihtout using a tracking mount, I took 64 images (+ 20 darks) that I superimposed with DeepSkyStacker software.
In order to improve the clarity of the photograph, I used lightroom. But the focus is not perfect unfortunately...

I was quite happy with result, but when I looked monitor from different angle, I was quite terrified.
I really have to see these photos with good monitor to see are they really so bad..
I tried calibrating system, but somehow it didn`t work like it should have.
Still this is a little bit better than my last one of this.

Traveling 2400 yrs. back in time (378 B.C.): the H-Alpha view of the *Veil Nebula*, the remnant of a supernove 20 times more massive than the Sun.
The picture is a 171 minutes integration of the Veil Nebula using the RASA 8, AVX, ZWO 294MM PRO and the H-Alpha, O-III and S-II Baader 2" Highspeed filters.
The stars are rather poor, with coma and bloating, but I was pleased with the spiral structure of the galaxy.

This has been relegated to my "Not good Astro!" set, and has been reprocessed here!
Continuing my current love affair with all things Cygnus, I thought I'd have a crack at the Milky Way up there. This was my first attempt at this, and it wasn't as easy as I was expecting. This is also a first inasmuch as I managed 4 minute subs unguided, something I thought would never be possible with my kit. Best I'd managed before was 90 seconds. Mind you, 18mm helped, but I didn't think my skies would allow it. We live and learn.
Hard to believe this thing runs over the top of my house. :)

Stacked and processed in DSS and CS5, with a little help from Noel's tools.
I'll definitely be having another go at this, maybe at 35mm and f5 or something. This was difficult to process - put it through DSS 6 times using different settings. I couldn't get the stars under control. I would have expected more detail for 4 min subs, but f7.1 and 1000 iso may not have been the best choices.
This learning curve goes on forever! :)

Do you know, I sometimes wish my camera was alive, so that I could kill it, or at the very least cause it some severe pain. But it's not, so I have to make do with kicking the cat, who now runs to the end of the garden every time I set up my kit. ;)
This is a vast improvement on this, but is still lacking in detail because of the conditions at the time (and the kit) (and my processing skills). The eastern veil (northern in this) shows much more detail, being the brighter, and even has some elements that could be loosely described as filamentary. :). Enough of the veil already!
