Binning at 2x1

[adamsp123]

Has anyone binned in 2x1 mode? ie bin 2x in either X or Y leaving the other direction unbinned and if so what happened?

Interesting thought... I haven't seen an imaging software which will give that option(!???) All I've seen are 1x1, 2x2, 4x4

You can in post processing use column combine to get any height of pixels summed into a single pixel. I use this for spectroscope work in AA4.

According to the setting options I have on my Atik383L+ software you can bin 2x1, not that I have actually tried it, I might give it a go the next time I get some good clear skies.

You can do this with Artemis capture. I did a few exposures one evening by mistake doing 2x1 and you just these odd rectangular pixels, kind of like the old Commodore C64 graphics. Not very pretty iin other words!

You can do it, yes. I know this because a guest once did so by accident, giving the Horsehead the Bob Hoskins look, more wide than high!! This has since been christened Hargraves Binning in his honour.

In fact we sorted it out out simply by resizing (10 seconds at most) and the image was very good indeed, to our great relief.

What remains to be considered is whether there might be occasions when semi binned colour might be a good compromise. Anyone want to waste a good clear night??

Hmm

Artimis Software has been mentioned...which other software supports 2x1 Binning? Maxim?

[ollypenrice]

I was in Artemis. AstroArt seems not to. I just checked.

OK clearly not a thing to do deliberately then!

[Merlin66]

Probably not for conventional astroimaging....but for spectroscopy it could be very interesting!!

i wonder if you can boost SNR if you 2x1 bin and then 1x2 bin and combine them to make a 1x1 image that has a higher SNR than a single image of the same duration....

Interesting idea I might give it a go

or will the result be effectively a 2x2 ??
