What did you shoot? May 31 through June 6...

[Jon Ruyle]

Last night after observing a few galaxies with my telescope, everyone's favorite pair of summer nebulae rose from behind a tree, and I decided to try a quick picture. It is a far cry from what the serious guys get, but given that it was only a 2 minute exposure (I didn't polar align accurately and I was too sleepy to haul out the autoguider) and taken from my light-polluted back yard, it didn't turn out so bad.


The field is just over 2 degrees, or a bit less than five full moons wide.

Lagoon Nebula (M8) and Triffid Nebula (M20)


5DII, Astrophysics 130GT + field flattener, 819mm @ f/6.3, 121 seconds unguided, ISO 1600


The field flattener really seems to control those star images at the corners (this is almost the whole 35mm frame). And I spent $90 on a special EOS adapter which was supposed to control vignetting, and it seems to have worked.


If I have the energy and time tonight, I'll try a longer exposure with the autoguider.

Jon, hi!


Nice picture. Can you post a crop of Trifid Nebula?


Thanks.

I had good fun this week playing with my new 100-400L.

Up until now my longest lens was the 70-200F4L so I haven't done any birding before or really any work at this kind of focal length. Any comments and suggestions would be more than welcome. I'm least happy with the first photo because of the lack of colour (overcast day) but I like the framing, the age of the bird, and the focus hit pretty well so I included it.

Hi Alex,


Sorry I took so long, but here it is.

You can see that 1) there is quite a lot of noise 2) the tracking isn't perfect, the stars are a little elongated even after only 2 minutes and 3) the seeing wasn't great, so everything is a little blurry.


Last night I took an autoguided 12 minute exposure which came out a little better. I also tried a 40 minute autoguided exposure, but I accidentally unplugged my computer at the start of the exposure and the thing died in the middle. Very frustrating. I'll probably try again tomorrow.

thought you guys and gals would get a kick out of this. my oldest hound bailey loves to pose.[8-|]

Hi cannon-ball,





Your dog looks smarter than some humans.





(Did you shoot with Canon lens or Tokina?)

[canon-ball]

that was shot with the kit lens ef-s 18-55mm





thanks, she is actually quite brillant as most boarder collies are. such a great dog
