Thanks Dave :smile: Will pick up a tele-converter and give that a go...Cheers for all the help!

Yes its taken with a 300mm lens @ f9, ISO800, 1/400sec that has been sharpened and cropped... I am sure that's why its noisy... I really wasn't trying to win any awards though... Again, forgive my ignorance, my first time photographing the moon...the effect does kind of look like stars if you...

Yea no worries, would'nt be a forum without it :) I reacted pretty badly too... Thanks for the info, pretty interesting stuff, I knew I had heard something along those lines..Thats why I sort of went along with it... Thanks too, Russ...Its great to have an answer, I am usually photographing...

Yeah that makes sense, was just kind of hoping for it to be something cool, someone had mentioned to me that it might be gravity bending light...feel kind of stupid for believing them... I originally thought it was just noise, definitely not dust though, if you look at the meta-data it was...

Well no offense, but I find it hard to believe that you could think that those specs were dust, they would have to be so small the sensor wouldn't even pick them up. Plus the light would be behind them so they would appear dark if anything, i thought that would be basic physics... Sensible...

Hey folks, A couple of weeks ago I took a photo of the moon, not sure if you will be able to see this in the image, but if you zoom in a bit after downloading it, you can see what I think are stars all over the background... ...The reason I say think is that I can see them through the...

ISO 50-100 is absolutely fine, just a problem getting the lights required to certain locations. Surely IR makes up some of the light in my image? I suppose what I was asking was, what it would take to get a clean image at ISO 6400 or more.

I'm afraid I'm a bit out of my depth here, but you most definitely experience more noise at longer exposures, its more noticeable in timelapses, which makes me believe that's it has more to do with 'thermal noise' that others have mentioned. Exposure compensation is normally controlled by the...

Not really just general photography, mostly portraits and landscapes, nothing too scientific. Getting clean Images at ISO 50 or 100 has been difficult in some locations, getting lights with enough power and a decent CRI rating outdoors is a bit of a nightmare. I Would do star trails sometimes...

Thanks for the reply, Wasn't sure what caused this noise, just a poorly informed presumption. Thanks for your help, have now been able to dig up a lot of information on the subject. Not sure how difficult it would be to mod my camera (CMOS) with a cooler, could be a nice project though! So would...

Hi firstly I am a photographer not a physicist, When taking photos there is always 'noise' in the image, especially at higher ISO. I presumed this is the same noise that we would hear on a radio, or see on a tv? Would it be possible to create a room that blocked out the background radiation...

Thanks for the quick response, can continue reading this book now! starting to understand it now, its a slightly different form of momentum than in classical physics because it isn't based on mass? So I take it that's how we convert light into electricity, by catching the electrons that are...

Speed of light and momentum? Hi all, I have just started reading about quantum physics as my uncles cousin was the late John Bell (Bells Theorem), so got interested in the subject, purely as a hobby! My question is probably very simple, but I have only started reding about this last...
