I've got a lot to learn about astrophotography post-processing, but this was the best I could do to preserve the faint tail. I don't know if it is wishful thinking or real, but it looks to me like the tail can be seen back almost to below the Pleiades. This was taken with a Tokina AT-X 90mm f2.5 on a Pentax K-5. A few exposures were stacked using DeepSkyStacker (which I'm also just learning to use). The camera and lens were on a Vixen Polarie for tracking.
Canon 5D3 with Celestron's CGEM 1100HD. Taken in the Northwoods of Wisconsin with fair seeing and very dark skys. Used ISO 1600 and a stack of eight (using Deepskystacker). Each exposure was 10 minutes with a dark frame of the same time. Manual guiding was done using Celestron's Off-Axis Guider and Orion's 12.5mm illuminated reticle eyepiece. Hope to get more images in the future for greater stack number to reduce grain.
This emission nebula is about 11,000 light-years away and rather dim at Mag 10. Its size is about 15x8 arc-mins (long lenth is 1/2 size of moon). The bright star off-center of the bubble is causing all the action (bubble due to solar winds, red emission due to its radiation). This star is 15 times as massive as the sun.
The reds are H II emissions and these occur very close to the cameras' IR filter so are reduced by a factor of 6 or so (no, I am not going to remove the filter on the 5D3!). These IR filters are unfortunate for astrophotography since the best images are H II regions (but OTOH it stops us from seeing too much of people we photograph!). I think Canin is going to be making the 60A, "A" for astronomy, that has the filter removed.
NGC4631 (The Whale or Herring Galaxy)an edge-on spiral galaxy. Its companion in the field of view is NGC4656/57 (The Hockey-Stick or Crowbar Galaxy) which is a highly warped barred spiral galaxy. Both galaxies can be observed in the constellation Canes Venatici (Hunting Dogs).
The original images were taken on 27.02.17 with a Canon EOS 760D attached to an 11" Celestron Nexstar scope fitted with a Starizona Hyperstar f/2 lens.

Managed to drag myself out over the last couple of nights. We've had several clear skies on the trot, but I've been too knackered. Very clear last night, and I wasn't intending to stay up until stupid a.m., but felt I had no choice :)
This is just over 2 hours in 60 second chunks, and is an improvement on last years effort, albeit a tad blotchy in places. May give this another go when I get the time.

Managed to get out last night and have another go at this. Conditions were much better and, to be honest, I expected more, although the extra data has enabled me to do a closer crop. I've put up several iterations of this, and this is probably as good as it's going to get. Reasonably happy now. :)

Nova Sagittarii 2015 No. 2 (an exploding star in Sagittarius, which was discovered on March 15th), photographed from my suburban Brisbane backyard this morning. For this image I stacked 10 x 8 second exposures (each taken using the Canon 6D and EF 35mm f/2 lens @ f/3.2 and 3200 iso) using DeepSkyStacker. It's surprising how much Milky Way detail can be pulled out after stacking, despite the Brisbane light pollution.
Stacked from 10 frames in DeepSkyStacker then processed for color, these plus another 90 were used non-aligned to make a star trails image. I believe each frame was taken around 5 seconds at f/1.4 and ISO 1600 or 2000 for reference. The D800 with the 85mm f/1.4 is just shockingly sharp. I need to figure out how to deal with the vignetting at the corners though as it really makes a difference in the stacking.

The Veil Nebula (part of it).
I used an unmodified Canon 5D, and I'm pretty unimpressed with the length of integration necessary to get this much of an image. Maybe it's time to look into a modified dSLR to capture more of the Hydrogen-alpha light. Although, I'm pretty happy with the amount of detail (check out the large view).

This is something I've wanted to do for awhile: a panoramic view of the Milky Way. Each part of the composite contains two fisheye views of the sky, the left centred on the Perseus Arm and the right centred on the Cygnus Arm. The uneven seam is because of the differences in the light pollution and sky fog from within the city.
The left edge is the north-east horizon and the right edge is the south-west horizon. The Summer Triangle is at the zenith.
Each part of the composite is itself a composite of sixteen 25 second exposures stacked with DeepSkyStacker and then converted to 8-bit JPEGs using Photoshop CS2's HDR Conversion (local adaption).

First attempt at widefield - the famous belt and sword in Orion.
I need more data in this to bring out the horsehead area more clearly and reduce the noise, and I need shorter exposures for the core of M42. Stars may be a little bloated because of the properties of the full spectrum sensor. Other than all that, I'm reasonably happy! :)

I remembered that I had a 135mm 1:2.8 somewhere so I dug it out and filled up a card with two second exposures to see what the extra stop would get me. The wider field of view means I can get the Orion nebula and the Flame Nebula in one frame, and Deep Sky Stacker helps bring them out. The Flame Nebula is the fuzzy divided patch just to the left of the left-most star in the belt of Orion.
DSS pinottu, 10x30s. Talosta löytyy myös EQ 3-2 seurantajalusta, jota oli tarkoitus päästä kokeilemaan kotigalaksimme kuvaukseen. Note to self: tarkista seurantamoottorin paristot ennen kun lähdet kuvaamaan tähtiä.
The Orion Nebula is a star forming region located approximately 1,600ly from Earth in the constellation Orion. There are believed to be over 700 stars being born in this nebula.
It is visible to the naked eye as the centre 'star' in the sword of Orion. (see Orion constellation in my wide field set of images)
Much of this nebula is illuminated by four stars in an open cluster called "the Trapezium." These remarkable 4 stars are just visible in this image in the lower centre of the nebula. There are reflection and emission nebulae present in this image. The bluish wisps are reflection nebulae, reflecting radiation while the red regions are emission nebulae.
