Ha for ngc253

[Crushellon (Tim)]

Hi all,

I'm currently working on ngc253 and I'm just wondering if it would benefit from a nights worth of HA data?

Looking on the net I can see some examples where Ha has been added. Is it worth a night of data? That's up to you.

You could take an exposure, stretch it and see what's in it and make a decision from there?

I think it makes a nice addition to emphasise the knots of Ha.

I just completed a Sculptor image last night with Ha, i will get it up on Astrobin later today and you can have a look.
