Keep it simple, stupid.
That is sound advice when it comes to post-processing images in astrophotography. Because, god knows, post-processing is enough to drive a beginning astrophotograper insane. Or was that just me?
When I joined iTelescope I knew that, in order to get the best images, I had to stack multiple images. My first attempt was to find something free. I know that the old "you get what you pay for" adage and I was quite worried about it at first. However, there are a few stacking software packages out there are quite good.
But what I discovered is that you need to find software that works for you.
Let’s list some of the freebies:
The costly ones:
(I know there are others, but I'm just listing some of the more popular ones.)
Now, on top of the issue of cost versus free, there’s the Mac vs. PC issue. And if you’re a Mac owner, you lose. Most stacking software is made for PCs, unfortunately (she says as a Mac user). But there are ways around that, like running Windows inside virtualization software, like Parallels, Fusion or Virtual Box. If you can't do that, then the best bet is to use Nebulosity
I used that and found that its simplicity worked for me. Though, admittedly, after using some other software programs, I discovered that it can be quite limiting. I tried using Keith's Image Stacker, as well, but really didn't like it. It just wasn't for me.
I did end up purchasing CCDStack, which I immediately fell in love with.
But this isn't meant to be a review of programs.
Basically, when looking at software, the thing you need to do is look for what works for YOU. I like to keep things simple. I like CCD Stack's simplicity, but then again, so is Nebulosity. I can't have anything too technical, though I'd love to try MaximDL as I hear very good things about that software.
What about you? What software do you use?
