Tessercts, that is awesome, I'm well jealous that you got the eclipse, and that is a great photo!!
DogLovingJim, that is the result of processing a 'stack' of photos (a series of pics overlaid to enhance along with set blank pics to remove noise) taken with a Nikon D3100 with a 70-300mm lens at 300mm, processed in the DeepSkyStacker program.

Ah nice, so like you put multiple pictures on top of each-other with each like a different emphasis on colour right so together it looks all vibrant with colour? When it comes with pictures, what do you mean by "noise"?

Not exactly DogLovingJim, you try to take a bunch as similar as possible so as when they are processed they bring out the weaker stars that might not show up well on individual shots. Some people do make multiple stacks taken through different coloured filters, then process them through Photoshop, but that's above my 'paygrade' at the moment.
'Noise' is basically regular glitches that affect the camera's sensor over longer shots. So you take a bunch of shots
with the same exposure as the 'coloured' shots, with the lens cap on so the sensor is shielded from any light. Then you get these stacked too and subtract them from the stack of 'coloureds' to eliminate false-positive sensor firings.
I hope this helps.

Well I'm certainly learning more with each question I make. So basically what you're saying with the first part is that you try to take multiple pictures of the exact same location and style (lets say for example 50 pictures) and sort of combine them, so that if one star was only visible on photo #34 and otherwise not bright enough than in the stacked photo it'd be on it?
And thanks, I appreciate it.
