Digitised Sky Survey data.

Anybody else tried the downloading of images and then processing them as per Practical Astronomer this month?

First go at 1/3rd the size it comes out at after DLing.

No I haven't tried this yet.

I have tended to use Aladin/Simbad, but these only give you B&W pics.

Thats a good image you've created. Looking forward to seeing some more.

Cheers

Good image the KK, can't get Practical astronomy here, what is the process?

First step is to ge here http://archive.stsci.edu/cgi-bin/dss_form to begin.

Plonk a Messier or NGC No. in the top bit and it will work out the co-ordinates for you, or enter them manually.

Poss 2 (Red) at the top of the list gets you a red filtered , image first off, so hit retreive image and tell it where to put it. Once you have a red, do it agin with the same co-ordinates but use the Poss 2(Green) source, then for a green I used the Hubble option HST Phase 2.

Once you have the data downloaded, pretend that you did it and process as normal.

You have to enter the size for a Messier etc. manually as I don't think it looks up the size, and don't check the "save to disc" box as it appears to wrk the wrong way round.

Might need a "stolen" section in the DSO imaging section if this catches on.
