    Default Landscape Astro Star Enhancement for a Newb



    Hi all, I've been getting into Landscape Astro a lot recently (from regular photography) and want to enhance (ie make bigger/brighter) some of the stars in my pictures but have no idea how. I've searched online and there's loads of plugins and photoshop actions for sale but I'd rather have the ability to work it myself from inside photoshop. I'm not normally into astro so not sure where to look, I'd appreciate it if there's a guide out there that someone could point me to, or blog/website/YT channel? Thanks!

    The basic idea would be to create a star mask and then work with the stars only to increase the brightness and contrast.

    Doug German has a few tutorials on Y-tube that should give you the basic understanding and from there you can experiment further.
    Processing a astro image takes time and skill and plenty of practice, so good luck.

    Dough German star masks in PS.

    I think you are talking about making stars more distinct and brighter, rather than fuzzy and dim? Are you taking a single photo ?
    If so, you can "stack" the stars. The stars are aligned and the data is averaged and filtered to enhance the "SNR". I can show you a single milky way photo compared to combined photo or a long exposure shot of the milky way. There is a big improvement if you do it correctly...

    Are you mainly interested in milky way photos?

    Hi, yes it's mostly milky-way shots and trying to make certain stars more distinct and brighter. Currently I'm just doing single shots.

    There's a lot to learn. Single shots will get you reasonable exposures if you in a very dark sky site. Otherwise lots of shots, at least 5, preferable 10-20 at least. If you have a Mac, there is Starry Landscape Stacker, and if a PC, Sequator (free download), or maybe DSS could do some work with some difficulty as a landscape foreground is involved. Check out LonelySpeck website by Ian Norman, or his Youtube channel. Hope you have lots of fun getting spectacular Milky way shots!
