If you could do any aimed at the stars, then just a couple of shots at f/2.8 with stars across the frame, 100mm and 150mm. Doesn't matter if you wind the ISO up to 6400 or so.
Haven't forgotten about this yet :D

Finally getting back to this, after waiting a week or so for the stars to align, some rain/clouds, and getting knee-deep in brightwork. I tried some last night but I couldn't figure out the focus. I think I finally did figure it out but too late to take any shots. (it doesn't help that it stays light until after 9 and astronomical twilight isn't until 10:30.) I think I'm getting caught up with diversions though so I can start playing with this again in the coming days.

Thanks, but no rush.

For focusing I set the camera to Bulb or Time to brighten the display, then I wind the focus ring close to the infinity mark to get rough focus. Then I centre the display over a bright star, switch back to 60 seconds or something, turn on magnified view, and then fine-focus the lens. (Magnified view doesn't seem to work with Bulb or Time setting).

I have much the same problem here with weather - cloud, showers, fog. Often all in the same evening. At least it's dark enough for imaging by 7pm.
I have managed a few frames using the 75-300mm, but it is slow. To get enough exposure with that lens I need 4-minute frames, and that is a pain pushing the shutter button every 8 minutes (4 + 4-min for noise reduction). I have an intervalometer on order but there are very long shipping delays with the lock-down.
f/2.8 lenses are a blessing, only 1-minute exposures.
Cheers,

I bought 40-150 PRO for action photography... and since then I stopped using PanaLeica macro...

@3dpan …better late than never. I finally got a free evening coinciding with decent conditions: low humidity, clear skies, and late moonrise. Took a few test shots, although I'm pretty sure I don't know what I'm doing. even at 4-8 seconds it looks like I'm getting star trails. most of the shots were facing north(ish)--too far north and I get too much light polution. Think big dipper, not little dipper. Also I'm poor at focusing. I've included full exif data I think, but please feel free to comment and ask for different settings.
My goal was to photograph the clown comet (pennywise's nephew neowise?) but I got there after comet-set so I'll be back out in the coming days/weeks

For those not interested in stars, here's the obligatory photo:

Thanks for those test photos. Very Interesting. At 40mm there is a little bit of CA visible on the brighter stars, but that seems to disappear as you zoom in.
Lens reviews say there is some coma at all focal lengths, but I can't see it in your photos. Might be visible at 100% but I couldn't download your pics to try that.
So, very encouraging as an astro lens, especially as there is nothing else vaguely affordable in the 150mm f/2.8 range.
Cheers,

You should be able to see full size on flickr if you click the "download" icon (bottom-right of the image) and select "view all sizes". LMK if there are specific picd you want and I can send raw as well

That worked. At 100% there is weeny bit of coma at the lower focal lengths, but negligible at 150mm. And the same for CA.
Thanks for all your efforts. It's difficult to interpret the lens reviewer test results in comparison with the real world.

Hi Alec,

Having just started learning astrophotography, I did a quick test of the 40-150 PRO on the Andromeda M31 galaxy, zooming in fully to 150 mm. I don't have a tracker, so I am limited to 1 second f2.8 exposure at ISO 5000 - not really brilliant. I did a stack of 40 exposures with 18 dark frames from a tripod. Sadly, at this exposure, the galaxy cloud is barely visible. It's better seen even at 7 mm with the 7-14 PRO when using a considerably longer exposure time (~20 s).
Camera used was OM-D E-M1 Mark II.

If interested, have a look at the full size jpegs and of a sample .ORF file here: https://drive.google.com/drive/folders/1GkWVbIV-oeYJWXBJmTFvFv-LdZUgISIq.

Looks there is some coma in the image corners wide open at 150 mm, but not too bad. I wish I had a star tracker!

Thanks Marko, I downloaded your ORF file and managed to stretch it out a bit. Again there is a fraction of coma in the corners, but really only visible at 100% magnification. Not really a problem I think.
I do think that high on your shopping list will be a tracking mount. It opens up a whole new world of astro imaging.
The iOptron Skyguider Pro may be an option. Or something similar.
Cheers,

Next one is a tribute to Robin Wong’s typical subject to show the sharpness of a lens:

But perhaps my favourite shot isn’t an exotic, just one of the natives:
