Hello, here is an example of what is evolution!
The first two above:
180 mm newtonian homemade telescope
Canon A460 (with CHDK). Non-focal method
EQ3 auto-guided mount
10 x 30 seg (something like that)
Stacked in Registax 5.0
Post-processing in Photoshop
Year: 2010
Light pollution: first (yes, a lot), second (not so much)
P.S. The camera was coupled to the telescope with a scotch tape =)
Then comes Jailton Cesar (the last picture)
OK. That's it. You can see details about this one in a couple of past posts.
See ya!
