OM-1 Starry Sky AF - Anyone?

I'd say 'f/5.6 or brighter'.

Yes.

See https://cs.olympus-imaging.jp/en/support/imsg/digicamera/qa/products/em1m3/#02

Note: elsewhere it is said that these two are not supported: M.ZUIKO DIGITAL ED 14-42mm F3.5-5.6 and M.ZUIKO DIGITAL ED 17mm F2.8

I've found the OM Ambassador for astro: Peter Baumgarten and his page with photos (including exif).


I think I'll be OK with the M.Zuiko 12mm F2.0. From his page there was a link to a page discussing Starry Sky AF:


However, anyone using an OM-1 and Starry Sky AF who can share images or tips - I'd love to hear them!

High Gary

I had a chance in the Upper Engadina to try for the first time the feature. Before I suceeded to use it I was quite confused at how to handle it.

4 examples here





And sorry. After 3 months since the shooting I can't exactly recall how I did it. One thing for sure: I put the feature on MyMenu.

The OM-1 manual states:

grsnovi said:

Starry sky AF is available with Micro Four Thirds lenses made by OM Digital Solutions or OLYMPUS. It cannot, however, be used with lenses with a maximum aperture over f/5.6.

Has anyone used this feature on an OM-1?

What lens did you use?

Hi Gary,

I’m by no means proficient in starry af but is sure works ok for me…

obviously not wide view but it worked fine for tele

Excellent pictures Dave. I assume that they were stacked, which software did you use?

Thanks Antonio,

not stacked, single shot, 150-400 on a tripod with tracking head but taken in hhhr mode

Well, those are amazing. Saturn rings very clear, and the belts in Jupiter cearly seen! Fantastic!

I’ve used the Starry Sky autofocus feature for a couple of years now, first with my now-traded-in-on-the-OM-1 E-M1 Mark III and now with my OM-1. I have it set to “accuracy” rather than speed because I always use it with the camera and lens on a tripod, usually with a tracker. There are three choices for how wide of a focus box to use, and I suggest using either the mid-sized or large-sized box (I think Peter recommends doing the same). I have mainly used Starry Sky autofocus with two lenses. First, I used it with my Panasonic f/2.8 35-100mm. So yes, it works with Panasonic lenses, at least that one. Second, I now use it with my Oly f/5.0-6.3 100-400mm and almost always with the lens zoomed in all the way to 400mm. Over the several times I’ve used this feature I’ve learned that it may fail to achieve focus on the first try and I need to try a second or even a third time. But it seems to always get focus, and the focus it gets is right on the mark.

Below are two photos I’ve gotten using this feature. The Andromeda Galaxy was taken in November of 2021 and was posted here in a thread I started about it around then. It was taken with my E-M1 Mark III with the Panasonic 35-100. The photo of the Running Man and Orion Nebulas was taken on January 20 this year with the OM-1 and the Oly 100-400mm and was posted here in a thread I started about it about 10 days ago. Both photos are the results of stacking many images and then post processing in SIRIL and Photoshop (the Andromeda Galaxy) or PixInsight and Photoshop (the Orion and Running Man Nebulas).

I think you will find Starry Sky autofocus is a great feature and one that really facilitates one’s ability to do astrophotography.

Starry sky focussing works well with my Oly 12mm F2, 8-25 F4 and 12-100 F4. I also use it with my Oly 100-400 and it works ok with this lens so long as I have a few bright stars in the central part of the viewfinder, otherwise it might take a few attempts to lock onto the focus.

Thanks for the links!

I'm curious how you process those images - there seems to be "fine scratches" visible when I zoom all the way in (almost like the images were printed and then scanned from a print). Are they just artifacts from your post?

I'm hoping to be able to get out with the lens next week.

My long lens is the PL 100-400 so I won't be able to use Starry Sky AF if I try shooting planets or Messier objects.

Your shot of Saturn looks pretty good.

Interesting! I wonder if it will work with the PL 100-400? I do have a copy of the M.Zuiko 12mm f/2.0 on the way.

This is awesome! I assume multiple exposures and tracking mount? As well as use of filters and subsequent color manipulation?

Yes and no. Yes to multiple exposures (33 2.5 minute exposures) and tracking mount (Star Adventurer GTI). But no to filters, not counting the high-quality B&W clear protective filter on the lens. And color was enhanced in PixInsight and Photoshop. Give your PL 100-400 a try with Starry Sky autofocus. I think the chances are good that it will work.

You did cause me to Google 'does Venus have any moons?' though, as I was suddenly uncertain. (Answer is "no").

And while many like to watch the 4 Galilean moons of Jupiter do their re-arranging dance Jupiter has something like 92 moons.
