Milky way..canon 10d

[Starcrazzy]

Hey guys...i thought i'd snap some milky way shots tonight with the canon 10d..despite the rotten tree in the corner, not a bad shot i thought..pretty much untouched, (alittle contrast fiddle in PS)..10 minute exp, iso 1600..can anyone tell me why there's red patcjhes down the right hand side??mabye the lense is had it??

cheers

That is a very nice shot, the 10D can take some great images, even if it is a few models old. They still produce great shots, time after time, as long as you do it right, which you have.
Well done, worth printing on an A4 size and framming.

Wow, even though there's a lot of jpeg compression it's still a mighty fine shot. I'd love to see a full version (with no compression).

What lens did you use? What was it mounted on?

How do you process your widefields?

Did you consider taking multiple shots and stacking them?

camera amp noise and maybe a refelection off the tree of a red light source behind you or from you on the tree.

Yes, Lens is definately had it; any unwanted or had-it lenses that fit Canon Eos can be posted to my address to releave you of their burden.

Jokes aside, very nice shot, I am drewlling.

Excellent shot Starcrazy,

The lens is fine, it's noise from the internal amp being close to the sensor and it happens to most models. I usually crop that side out when using the 300D. I just plan my frame with this in mind knowing that the corners will be cropped later.

Keep up the terrific work SC.



PS Also, like Houghy said, it looks like there is a light sorce illuminating the tree from the side.

Yep, nice shot there. Astro processing software may get rid of the amp glow, though for my 50mm lens shots turning on the in camera noise reduction helps best (Only present in newer models)

thanks for the reply's guys...I had the cam piggybacked to my 8" newt on an eq5..I used the scope to guide as there's a fair bit of r/a drift in my motor...The only processing the image had is in photoshop where i played with the contrast and brightness abit..and shrunk the file size of course..I do have a few other shots of different exp times of the same frame...i will stack them today in registax and see what happens....
ps..i do have some more on a higher zoom of the central bulge (and without the darn tree in it) that i think are more impressive but p/s can't shrink them below 150 k/B...any tips??
cheers

Change the mode to 8 bit (if not already), resize the image to something like 700x400 then goto "save for web" and save it to below 150k

[Striker (Tony)]

The shot looks nice...very well done for just 1 exposure.

[Gama]

To shrink the image down more, you could save it at the lowest size you can get it. Then load it up again as a new file, then save again using the lowest size once more and so on..
Thats how i do it.

Top Shot Starcrazzy.

Yep that amp glow can be a pain, but as Andrew says it's easy enough to take it into account when framing your shot and crop it later.

As for resizing your image, I did a short how-to here on using Photoshop to adjust your image for upload. There are a few other programs around that will do a similar thing (discussed in the thread) but for large file size photos PS is great for resizing and keeping control of the quality of the resize and compression.
