Any astronomy lovers around?

Yay for luck The sky has cleared up about 40 minutes before the end of transit.

Here's a pic I snapped. You can see some sunspots as well.

My setup consisted of a Nikon D5100 plus a Nikkor 55-300 telephoto lens with a homemade mylar filter:

Here's a photo that won me a nice pair of binoculars for the first place in the astrophoto contest during a star party I attended last week


And here are all the prizes and gifts I got in various contests, quizzes and events in the last 4 days

really nice photo barman.
how did you do that, rotating the camera ?

[Kaleu]

amazing but I can't understand the photo

[Dulek]

really nice photo barman.

Long exposure time I guess.

Fss, so you prefered to make pictures instead of meeting me, shame on you! Great photo btw.

The camera is not rotating, the sky is! I took 120 pics, each with an exposure time of 30 seconds and then stacked them together in Gimp with a "Lighten" blending mode. This way, you can see the paths of the stars during a 1 hour period

That pic is sick!

Put it on my background.

barman that pic is impressive. It got even more impressive when you explained how you did it

[TheKomodo]

Yeah that's incredible barman very good work, my Brother is doing some Astronomy courses at University, he's spent so many thousands on equipment over the last few years you should see this moving mobile hut thing he's building lol, i'll get some pictures or something soon !

This is really fantastic :O compliment !

The sky is not rotating, the earth is!!! 

Vns barman! It looks like it's a pretty wide angle, can U tell me what lens have U used?

Here's my startrails from few months ago with 18mm lens, I don't have a remote shutter yet so U can see a little pause between series of 10 photos... It's a stack of 220 photos, 30 sec each (also). Stacked in http://www.startrails.de/html/software.html - cool free application, U can make timelapse videos with it also..

[Statik]

nice, and I would say... everything is rotating relative to something

[barman]

Good photo there, don't hestitate to bump up the ISO sensitivity in order to record more stars, the noise becomes less apparent after you stack a lot of images.

Vns barman! It looks like it's a pretty wide angle, can U tell me what lens have U used?

Samyang 8mm fisheye, stopped down to f/4.8. ISO 6400.
This lens is extremely wide angle indeed, about 180 degrees across the diagonal of the frame.

More pics:

Andromeda Galaxy - Samyang 85mm f/1.4, stack of 32 exposures 6 seconds each, ISO 6400


The North America Nebula in Cygnus - same as above


The constellation of Lyra - Samyang 85mm f/1.4, single 8 second exposure, ISO 6400


All of these photographs were taken with the camera mounted on a tripod, without any compensation of the daily rotation of the sky Earth. This limits my exposures to about 6-8 seconds, any longer times make the images of the stars spread out into little streaks. I'm going to buy some tracking device really soon, this will allow me to enter a whole new level of possibilities
