Hi all. As I've not long had the new canon and it having been cloudy every night since I bought it. I've been teaching myself how to use it and am loving it. So last night, finally , some clear sky and went out to practise some.Put it in manual, used settings that you all mention and took some shots. The ones I took at 25 seconds seemed all right color wise etc. good focus, slight trailing of course (pointing straight up) because I had on the 50mm lens. Then I tried a couple longer 3 min. exposures on the barndoor just to see what would happen and they came out bright pink. The sky was pre-dawn but still dark. I was at f2.5 and 1600 iso. using a plug in shutter timer. Thanks. oh, and it was set for 1 raw and 1 jpeg.
You say still dark, but was it "dark" or yes I could see the horizon was lighter than the land?
Because the 1600 ISO with 3 mins will give you A LOT OF LIGHT in your lens.
Yes it was dark, an hour before sunup. I guess like you say 1600 iso is too much. I wouldn't think it could be anything else especially as the half min. ones were ok. I'll try less time and iso next time. Thing is, I'm used to the point and shoot,you know, small sensor,small lens, low iso, so yea,big learning curve. And yes,I'm small town ,so middling pollution.
Yep LP. It is orange/pink due to the sodium vapor lighting.
There is also the possibility it could be Aurora if you were shooting lowish inthe south, like at the SMC or LMC.
Not sure if the 1100D has this "problem" but DSLRs aren't designed for astrophotography. As such there's no effort put into ensuring the sensor is cool, and in long exposure it heats up. This shows up as pink bleeding into the frame.
The higher the ISO the worse it is. I have seen the same thing on a much more expensive DSLR in a 45minute exposure at ISO200, and typically after about 5minutes at low ISO you start to see pink creeping in from the edges.
In short it's normal. Lower your ISO, or lower the shutterspeed and instead take multiple frames.

Sorry but no, it's not normal.
I assume you mean amp glow?
Haven't seen amp glow in a Canon for some time, I can't vouch for other brands.
I have gone 20mins at 1600 with not even the slightest hint of what you describe.
I have one of those, too - attached. Do yours look similar?
pretty, eh?
5 seconds, ISO3200, 172mm with a Sony Nex-5N
It has happened only once and I put it down to some software glitch - maybe related to the new, bad zoom creep (?) I was still trying to fix, back then. ( a rubber band solved that.)
Your ISO is much to high, 400 is perfect with a 50 mm, and although it was a hour before Sunrise you would be surprised how much dawn glow you would get, mix that with light pollution and you would be in for a image you described.

Depends on the camera. I've seen it in Nikons, Canons, and Olympus models. Seems to be model specific. That said my experience with new cameras is limited. Certainly it was definitely normal several years ago.
Can't vouch for the 1100D though. I have no experience with it.

Yer this is what i would say is happing as well, just grab a air rifle and keep at them lol. It sucks where i'am, as apart from a few of these covering the area LP isn't that bad, it just means anything 30 degrees and under is out of the question. You can also add light sheilds on your fence and scope end to help counter this to an extent.
