I tried out one of my medium tele lenses in the afternoon on the Moon with some buildings in the foreground a couple of days ago. I noticed there were some small black spots in the photo close to the Moon, so I digitally magnified the photo to see what it was:

Ordinary birds, or... much worse? To my eye some of them look suspiciously similar to Klingon Warbirds. :biggrin:

Heh: "moonwatching".

Not as good as this one, but not bad for urban astrophotography...

SkyGems "preview" of M104 (Sombrero).
Observatory: Hakos iDK 20"
Filter: Luminance
Duration: 800 seconds
Charged with: 4.228 points

Due to a software issue the raw data was lost on the way from Namibia, so they refunded me. So now I have 6 points (need more suggestions).

There are some nice examples on their Results page, they are not just pretty pictures 😲.

Earth Restored

Only 24 people have journeyed far enough to see the whole Earth against the black of space.
The images they brought back changed our world. Here is a selection of the most beautiful photographs of Earth — iconic images and unknown gems — digitally restored to their full glory.


Photo page with many fine photos is here: http://www.tobyord.com/earth

Example (what a photo! :))):

What was your shutter speed for the white? The green? What time of day do you take your images?
 
  • #1,346
Hi, it was about 4 afternoon and made by SV EBONY eyepiece camera with exposure adjusted on cca 2.0 ms
and very low gain cca 2 for all images. Subsequently I made little sharpening and highlighting of spots in Gimp. :wideeyed: :confused::smile:

A slice of the Moon

I saw a nice, small Moon yesterday evening, so I fetched my gear and took some shots before it disappeared behind the trees, using my vintage Tokina 400mm f/6.3 tele lens (set at f/8). Camera settings: ISO 1600, shutter speed 1/500 s.
