Fuji 23mm f2 Astrophotography
20

The 23mm F2 was my first lens I picked up for a 'song' in a package deal with the X-T30. While I wasn't expecting too much in terms of astro capabilities, I took it out for a spin on a recent business trip. It is quite compact and easy to take in a carry-on bag for an all purpose little kit with the X-T30. I only had a rinky dink plastic mini tripod with me. So some shots had shake. But overall, I was very surprised with how well the lens held it up under the stars. Coma wasn't noticeably a problem either. I still plan to get a more 'dedicated' astro lens eventually to cover wider views in addition. But in a pinch, this little 23mm works surprisingly well at night, definitely outperforming my expectations.

You played the hand you were dealt.

Nice compositions.   Well done.

Wow, that looks great! Nice to see others shooting astro with it as well.

I know what you mean about manual focusing being tricky. I'm still learning how to do that with the lens. Of course, I was trying to do that from a flimsy 12" tripod. Your shot looks better focused.

Fantastic! Care to share how you pp the shots? I am really curious to see how is the shot from camera and how it ends up after pp. My Astro efforts were both bad before and after pp 🙂🙂

Thanks, Yannis. It does take some time to learn the pp aspect. And that is really where the stars come out more. I'm certainly no expert, though I've learned techniques mainly through trial and error. There are a number of really good sites with detailed steps which I've gleaned from. Lonelyspeck is a good among others:

How to Post Process Milky Way Astrophotography

My basic steps are:

1. Shoot RAW and convert in favorite converter. I like Capture One for Fuji (free). Try to get a good white balance here with some other basic adjustments.

2. Take into Photoshop to pull out the stars and adjust mainly with curves, levels.

3. Focus on different parts of the image (sky, milkyway, foreground) in separate layers, then combine.

4. If noise reduction is needed, use another program for that.

Here one example right after RAW conversion and the second after pp in PS. Note, that I had underexposed it too much (ISO 2000). But Fuji has pretty good ISO invariance which helps.

Yes, I've shot there often and its a fabulous place to go at night. Here's a couple from my old Canon 6D & Tamron 15-30/2.8 (single exposures). That's a beast of a lens but very good for astro. I really like to go wide here because the milkyway is so clear. Its nice to get more in frame. That's probably why I'll also pick up a SWA astro lens for Fuji.

One more from the Tamron 15-30:
