So I have a dslr and webcam for planetary imaging, which should I use?

#

I can either get a dslr adapter or webcam adapter

#

Probably the webcam, they have the smaller pixel sizes typically

#

What camera is it?

#

webcam also means you can get raw frames, most DSLRs don't have raw video

gaunt plume What camera is it?

Logitech c120

#

It's pretty old

#

records in 480p/30fps

#

so uh is it REALLY better than dslr?

#

Oh wait you meant camera not webcam

#

It's a Nikon D3100

#

so our contenders are: Nikon D3100 Camera, or Logitech C120 Webcam

#

The nikon d3100 has no manual video so I was thinking I could quickly take pictures with a remote shutter release

Give them both a go and see what works for your but the webcams pixels are smaller which is like planetary cams

Damn I didn't think a webcam is that much better than my dslr

the main thing is raw video frames that aren't compressed, which is what you really want for lucky imaging and stacking in AutoStakkert etc.

#

plus likely smaller pixels for more resolution

#

The webcam is only 480p

yes, but the sensor is much smaller so I bet that pixels are smaller than on the D3100. also, with video you can make 1800 images per minute, or about 9000 images in 5 minutes, with single exposures on the DSLR you can make maybe a few hundred

#

you then run the video into https://www.autostakkert.com

AutoStakkert! – AS! Stacking Software – Lucky Imaging with an Edge ...

AutoStakkert! (AS!3, AS!2) is lucky imaging software used to automatically analyze, align, and stack images of the Sun, Moon and Planets that were taken through a telescope. Using a fast video camera, noisy and slightly distorted images are obtained, that can be combined into a single high quality image using this software. AutoStakkert! is free...

#

and keep the maybe best and sharpest 25% frames and stack those
