#lunareclipse2018 as the moon just begins to move out of shadow.

This image is actually a stack of 10 images, that's what it took to get to this level zoom from the 135mm lens on crop sensor raws.

impressive, what was the configuration of your camera/lens ?

@akira Thanks!

I use a Sony a6000 with a Samyang 135mm F2.0. I think it was set at F2.0, 1 sec exposure and 200 iso.

This is not a raw image through.

I stacked 10 frames in total (that was shot in 2 batches) to double the resolution in each dimension and to help with the denoising, and to top it off, this is a detail crop from the final stacked frame, that is about 2500x1700px.

I hope this helps. :)

@eylul thanks for the information, I was asking myself how to take more details without burning the moon but I took photographs with 10-30 seconds of exposure.

@akira oh! well the exposure depends also on the aperture. Normally moon is very bright and doesn't need that much exposure (1 second on a huge aperture like F2.0 was only because this was an eclipsed moon that is a lot dimmer)

Also on night sky you do not want to go over 15 seconds on even on a wide angle lens due to stars shifting blurring the image. On a telephoto lens, that time is much shorter. (e.g. I started getting visible blurring even on 4 seconds while photographing this)

@eylul
yes, i heard sometimes to use long expo. but with my 50mm i had certainly no chance to see that it was ok on the screen. so too bad to forget my 200mm lens this day ^^

@akira heh, it happens. :) stacking can also be replacement to a longer exposure, if movement is an issue by the way. (that's actually how a lot of deep space objects are photographed) and now I will stop geeking on this ;)
