In case anyone is interested - this is the best site EVER (after BF of course ;) ):

Click on 'Discover the Cosmos' to see the archived photos. A new shot everyday of some pretty spectacular stuff. Photos can be clicked on and most expand much larger.

Enjoy

What, they don't want it to have puppies? :)

Oh yes. I've been checking it out daily for years now. There's an amazing amount you can learn in 30 seconds each day over enough time.

Here's my 2nd favorite of all time (after "Earthrise"). The little blue dot just outside the A-ring is Earth. This is literally a $2 billion photo.

Yeah, that's an amazing picture.

I used to check on APoD once in a while, but I haven't in a while. It's good stuff.

What's sad is how much of the sky we miss due to city lights. I use to do a lot of fishing in the UP and the best part was coming out at night and looking at the sky. This is something my kids have never seen and pictures don't do it justice. It would be nice if at least once a year the world turned off all of the lights and people could really see the night sky.

The Hubble Deep Field photo is a long exposure view of the sky, an covering area the size of a dime 75 feet away. Every object in the view is another distant galaxy. See an extra large view here to get the full effect.

Sometimes, Apod just has cool pictures: (1) (2).

The 2007 pictures of the year are a good sample.

You mean all of these lights?

But is cooler to do your own, like these taken with a home made telescope with a $10 web cam and image stacking software:

I used to do AP too. I quit in 2005 and sold everything. The struggle for perfection against the rising tide of light pollution was unbearable. Out of 365 days in a year i was luck in 2005 to get my gear out on 50 of those. This is the very last image i took. Its a section of the Pelican Nebula shot with a narrowband Hydrogen Alpha filter. The scope was a 4" apo on a guided G11 mount using a 1.3mp cooled CCD camera. It was dark and light frame subtracted using 6 20min exposures stacked. I will revisit this hobby when i retire and move to a darker sky environment. By then maybe in can afford a nice R/C scope in an automated observatory.

Moon and planet photos were my favorites. I used a Philips Toucam II and my 4" apo pushed beyond extreme to get this image here. Its 2x original size.

Then i started using an ATIK b/w cam that did webcam motion and long exposure too. This saturn image is more true to color. I stacked separate Luminance, Red, Green and Blue images to create it. This picture is my Mona Lisa of planet photos. The crowning achivement of what can be done with a 4" APO refractor.

Now im sure the cameras are even better and had i stuck it out, I would have surpassed even that.

donheff 01-25-08 10:39 AM

I'm in awe FatGuy. I used a home made 6" Dobsonian my daughter built for a science project. I had read about web cams and stacking software so I gave it a try. Maybe someday I will get back to it with a motorized goto scope. I would love to get good shots of nebulae like your Pelican. Not possible on a telescope that rotates a wooden box on a 33 RPM with teflon bearings designed for chair feet :)

No kidding! I started browsing that site and kept clicking on link after link, wanting to learn more. :D I love this stuff...

I tried to image M31 myself, but it was always a difficult catch for me because of where it was in my sky. l couldnt ever get enough time on it before trees and the roof of my house interfered.

Yep, did a little AP myself. I used to surf Astromart like I do Bikeforums.
In 2003 I sold most of my astro equipment, including a G-11 mount, Tak 106, couple of F2 bodies, and a Nikkor 300/2.8
The only astro equipment I own now are several binoculars, including a couple giants.
This hobby used to take a lot of time away from cycling. Not good...

Astromart! Ohhhh. Dont get me started. Like eBay, only more addicting. :p

I'm still getting rid of stuff there and have a few more minor items to sell. I need bike parts!

Aside form hating the every increasing light pollution, I wasnt getting any sleep either. Now i get to bed at a normal time, like a normal person.

I still have an Orion Skywatcher 120 refractor and EQ3 mount. I may just keep em to stare at the moon.
