Practice Subs

[Seraph_69]

Hi all,

I'm not sure how ridiculous this request may be, but I won't know until I ask I guess!!

I am wondering if someone would be willing to 'donate' a set of subs to me, that I could use to practice post-processing on? I want to get into astrophotography, but I don't have a DSLR yet (and won't until I've paid off my lovely eye piece set!) - but I am trying to take in as much info on the post-processing side of things right now, and watching all these videos online/seeing people demonstrate the techniques at talks I've attended - I'm now just dying to start practicing, so that hopefully by the time I get my own camera and start taking my own subs, I will know what I'm doing/have decided on some tools/software I like.

 

If this is some sort of astrophotography taboo to ask for someone else's hard-earned subs, or people are worried that I'm going to pretend I took them (which not my intention at all)/some sort of copyright infringement - then I completely understand - just thought I'd ask!

If on the other hand someone is willing to let me have some subs to practice on, preferably a galaxy, as this is likely where I'll start with DSO astrophotography, and I want to learn to balance the core region with the arms, but beggers can't be chosers!

Thanks for your time guys.

It's a perfectly reasonable request. I hope the link will take you to a set of files from one of our CCD cameras, so you'll find luminance, red, green and blue. I don't use a DSLR so can't offer you anything there but maybe somebody will come along.

This is a simple 50 minutes per channel run on the Wild Duck Cluster from my place in SE France, Lat 44. I think it's a decent image on which to start learning post processing. It doesn't need anything fancy in the way of processing.

That is very generous Olly, thanks for helping us out.

If you want to have some more fun there's the Hubble data available at http://hla.stsci.edu/hlaview.html although the site seems to be down at the mo.

Olly do you mind if I have a play too?

Have a look at this site: http://www.rawastrodata.com/

There is a wealth of Galaxies, Clusters and Nebulae subs uploaded to practice with and also a finished image to compare your image with when your finished. Very handy for practice!
