Here is a wide-field view of the star Sirius and the open cluster Messier 41 (M41), just squeezing them both in the field of view using the Williams Optics Redcat and Canon 6D camera. Sirius, Alpha Canis Majoris, is also known as the Dog Star, Nile Star, The Sparkling One and many others. At a distance of 8.7 light years, Sirius is the 10th nearest star to Earth.
Located 4-degrees south of Sirius is the open cluster Messier 41 (M41). M41 has an apparent magnitude of 4.5 and is about 2,300 light years from Earth. M41 is also referred to as the Little Beehive Cluster, but I can’t find the exact reference. M41 was mentioned by Aristotle about 325 B.C. as one of the mysterious “cloudy spots” then known in the sky. (REF: Robert Burnham Jr., Burnham’s Celestial Handbook, 1978).

M71 (NGC 6838) est un amas globulaire situé dans la constellation de la Flèche à environ 13 050 a.l. (4,0 kpc) du Soleil et à 21 850 a.l. (6,7 kpc) du centre de la Voie lactée. L'astronome suisse Jean Philippe Loys de Cheseaux a découvert Messier 71 en 1745.
Messier 71 (also known as M71, NGC 6838, or the Angelfish Cluster) is a globular cluster in the small northern constellation Sagitta. It was discovered by Philippe Loys de Chéseaux in 1745 and included by Charles Messier in his catalog of non-comet-like objects in 1780. It was also noted by Koehler at Dresden around 1775.

Have some mixed emotions about this picture, the whole trip to Idaho I wanted to capture an image portraying the scale and awesomeness of the Sawtooth Mountains along with the big beautiful Milky Way behind them. The last night I was there I made sure to time it right so the core of the Milky Way and the Rho Ophiuchi complex were directly overhead the mountains. This would only leave me about an hour of shooting before astronomical twilight began. With my 24mm lens it was quickly apparent that it would not do justice to the magnitude of the mountains and the Milky Way, everything just appears "small" at that focal length.
So I switched to my 85mm f1.4 lens, probably my second favorite astro lens behind the 24mm. This meant I'd have to shoot a lot more shots to get it all in frame though. So I ended up doing 3 rows, 4 shots per row, in all the time it took to get setup and start shooting some high thin clouds moved in over the horizon. That in combination with the ridiculous airglow meant I lost a ton of detail, particularly in the Rho Ophiuchi complex, which frustrates the hell out of me. It also makes Mars, Saturn, and Antares appear utterly massive and other stars look blobby, again not what I wanted. I did manage to capture a nice meteor streaking through the Ophiuchi region though.
Given the number of shots it took the final resolution came out to ~17,000x~9,000 pixels, so you could print this up to 85 inches or so at a good PPI, which is pretty awesome.
Each image is a 3 minute exposure at ISO 400 and f2.5 shot with my Nikon D600 and Rokinon 85mm f1.4 lens, sky shots had my iOptron Skytracker mount turned on.

Another from the pseudo-surreal collection....I wonder what the night sky might look like on another planet, one which has little or no atmosphere to obscure light, maybe something like this?
I went out to the Bonneville Salt Flats last night and got a little imaging done, I'll have more later. I'm actually super happy with how the sky turned out in this one, pretty good details considering I only took 15 minutes worth of exposures (2 sets, one for the upper half and one for the lower half of the Milky Way core region). Sky was shot with my Nikon D600 and Nikon 50mm f1.8g lens on my iOptron Skytracker mount, ISO 800 and f3.2 with exposures of 5 minutes, 4 minutes, 3 minutes, 2 minutes, and 1 minute. The foreground was taken with my Nikon D7000 and Nikon 24-120 f3.5 lens @65mm, 1 minute exposures at f5 and ISO 800. Edited in PixInsight, Photoshop, and Lightroom.
I'd like to promote a group I've started for sharing Milky Way photos (ya, another one of those groups). It's a group dedicated to displaying accurate images of the Milky Way in terms of color balance representation. One thing you may not realize is that the night sky is not blue despite the representation by most night sky images. I myself thought it was not long ago, but actually most photographers have improper white balance in their pictures, chosen so as to produce what they believe is a more "pleasing" image. So I felt like creating a page dedicated to providing the most accurate Milky Way, Night Sky, and other astrophotography images with discussions and examples of this topic:

Taken from Cerro Llao Llao, San Carlos de Briloche, Argentina.
It's my very attempt at trying this kind of shot. I didn't choose the easiest way begining with a pretty large mosaic.
Hopefully, others will come...

This is a 56 shot panorama of the 'Summer' Milky Way over Lake Ninan, two hours north east of Perth in Western Australia. It stretches from the California Nebula on the left side of the image to the Crux/Carina region on the right, including the Magellanic Clouds.
This is the first panorama I have taken with a dedicated H-Alpha filter, chiefly to greatly enhance the Ha regions of the night sky. This particular filter was the only Ha type I could find which screws onto the end of the lens, all others were clip in filters which require the complete remove of the lens in order to install them. Not particularly conducive to the multi shot panormas I normally take.
Aside from the regions already noted, other prominent features in the image are the Gum Nebula, the large red nebula to the left of the LMC. Near the middle of the image is the Seagull Nebula and to its left is the very well known Orion Nebula and Barnard's Loop, with the circular Lambda Orionis below it.
I have been to Lake Ninan many times but this is the first time I've seen it almost completely dry. There were some quite nice pressure ridges around the edges of the lake which was unexpected and, again, something I've never seen here before. I'll post those images later.

However, thin haze and ice crystals added natural star glows. Plus haze and airglow added the bands of colour.

This is a combined (photostitched) image of the Horsehead Nebula and Orion Nebula that were taken in December 25, 2014. Exposure time was 29-minutes for each image. Using the software package Microsoft ICE, the images had sufficient overlap to be merged and then cropped into this final image. Canon 6D, Canon EF 400mm f/5.6L USM lens and iOptron ZEQ25GT mount were used for the exposures. The stitched image shows the true distance between both these marvelous deepsky objects.

Messier 44 – The Beehive Cluster (or also called the Praesepe) is a fantastic open cluster to view and photograph using a wide-field setup

M44 Facts
Praesepe contains at least 1,000 stars which are gravitationally bound. The bright, massive stars are mostly concentrated in the central region and the fainter, less massive members are found in the cluster’s halo. The total mass of Messier 44 is estimated at 500 to 600 solar masses.
The brightest stars in the Beehive Cluster have an apparent magnitude of 6 to 6.5 and are blue-white in colour.
A recent survey of the cluster has revealed that 68 percent of its stars are M-class red dwarfs, around 2 percent are bright class A stars, and 30 percent are stars comparable to the Sun, belonging to spectral classes F, G and K. Praesepe also contains five giant stars. Four have the stellar classification K0 III and one, G0 III. Eleven white dwarfs, stars in the final stage of evolution, have been identified in the cluster. These stars originally belonged to the spectral class B.

This is a 15 shot panorama of the Milky Way setting above a lone tree on a farm at Wandering, 1.5 hours south east of Perth in Western Australia.
There was significant high cloud cover on this night, I had hoped it would clear when I set out but it stuck around. The wispy cloud acted as a natural fog filter, diffusing the light of the stars and making them appear much larger while also enhancing the star's spectral colour.
