Bad weather always looks worse through a window… by Sandeep Thomas Via Flickr: - Tom Lehrer. | facebook | 500px | ferpectshotz | This was an old shot I took during a trip sometime last year. We visited while a storm hit the valley and pretty much had a washed out trip so I didn’t pay attention to the shots I made there until recently while cleaning up my drives. This one is a pano shot I made at the valley floor on a wet morning and you can see the pretty dramatic sky as waves after waves of could got pummeled into the narrow valley opening. One aspect of photography I am going to really benefit from is to have a wide tilt-shift lens that would allow me to pan more seamlessly. This photo for example did not align well and some of the key areas were missing focus along with the dreaded blank spaces at the bottom. Forcing me to do some creative cropping which king of changed the look of the image, more than I cared to see. I have already invested in a cheap pano slider and hopefully it will help me get some benefits in the coming road trip to Colorado.

Blank by Jay Daley Via Flickr: We had arrived in Dalmeny Campground to perfectly clear sky’s – it was looking as though it was going to be a lovely weekend for everything other than photography. Despite the lack of clouds Damien and I set the alarms for 4:15am and headed down to Camel Rock in the hope of catching some stars before first light. With the previous night’s wind completely gone it was a beautiful morning. A few star shots with the pre-dawn glow and it was time to launch Inspire. As it happens I caught some beautiful coastal images from the sky but later lost my micro-SD card from the X5 camera so was left with only one photo from that morning, and here it is.

Weekly Recap From the Expedition Lead Scientist by NASA's Marshall Space Flight Center Via Flickr: Crew members on the International Space Station captured this astounding image of the Aurora Borealis during a recent orbit. This natural phenomenon is the result of electrons colliding with the upper reaches of Earth's atmosphere and is usually only visible in the polar regions. To read highlights from last week aboard the space station, including astronaut Kate Rubins' check for microbes in the water supply to test a new monitoring system, click here.

Equipoise by Alpine Light & Structure Via Flickr: La Greina, October - the left-hand rock is by Henry Moore, the right-hand one by Barbara Hepworth. Priceless, of course. As a result, I must refrain from geotagging this picture ....

Lunar Craters by Davide Simonetti Via Flickr: An experiment in stitching together a couple of shots made from stacked video frames rather than DSLR shots. In the middle of the image from top to bottom are Craters Theophilus, Cyrillus, and Catharina with the smaller Crater Mädler to the east in Mare Nectaris. The shots were taken on September 8th in Sicily with the Mooon in First Quarter phase. Made from 2 x 1,000 frame videos captured with FireCapture and processed in PIPP, Registax, and Photoshop. Stitched in Microsoft ICE. Equipment: Celestron NexStar 127 SLT Alt-Az Mount ZWO ASI120 MC imaging camera x3 Barlow lens

And night.... by Graham Hendey Via Flickr: A 12 shot composite panoramic image taken on the bridge at the Causeway last night.., Sept.23rd. Freshwater Isle of Wight. I wanted to include as much of the night sky as possible as it was simply stunning with the cloud actually enhancing it for once!:-) #20

NGC 7000 - North America Nebula by Matthias Via Flickr: NGC 7000 is a emission nebula in the constellation Cygnus. Its distance is around 2000 light-years. The image shows the "Mexico part" of NGC7000. This image was created under bad conditions. The night was really humid, and there were still some cloud remnants in the sky. But for a test it was good enough. IMAGING DATA 8x 300 seconds ISO500 Total: 40 minutes of exposure time. EQUIPMENT Camera: Canon EOS60Da Telescope: TS ONTC 10" f4.7 Newton Mount: Skywatcher AZ-EQ6 Guiding: Finderscope, Lacerta MGEN Autoguider

Pleiades, Messier 45 (Collaboration) by Transient Astronomers Via Flickr: This image of the Pleiades is a collaboration between Terry Hancock(downunderobservatory.com), Tom Masterson(facebook.com/transientastro) and Kim Quick. Here's a link to Kim and Terry's image from Dec, 2014: www.astrobin.com/139805/ Terry and Kim's image was used to sharpen and brighten the center part of the Pleiades as well as bringing out faint dust immediately surrounding them. Kim collected 5 hours of LRGB using a Takahashi FSQ106/ST11000 remotely from New Mexico Skies which was combined, registered and post processed with 4 hours of Terry's LRGB data using a QHY11S/Takahashi E180 from November of 2013 and another earlier data set taken by Terry using a QHY9M/TMB92S captured from his home observatory in Western Michigan. Total integration time for their image was 13 + hours. My data was collected using a Canon 6D, Williams Optics Star 71 Astrograph on an Celestron AVX mount on 8/22/2015 in Los Padres National Forest, CA. My data supplies info for the outside area beyond the central star cluster and as a color palette for the image over all. I collected around 2 hours of data for this collaboration. Here's a link to my image: flic.kr/p/xrA3qU Here's a fun and interesting link packed with info on the Pleiades: messier.seds.org/m/m045.html
