I made another star trail image tonight given that the sky is clear - but this time with the area of the North star included. Which worked. Unfortunately, the camera's battery quit - but I didn't really loose the image - which I am glad for. It was after all close to an hour exposure - which I wouldn't liked to loose. (albeit i am now talking a second shot).

Be careful with how you scale down the image

Star trail images can be very tricky in regard of that when you make the image smaller - you can easily get jagged, weird looking star trails. Which unite in a sort of inference-pattern, which is plain ugly - and destroy the whole beauty of star trails images. i have often seen that on the internet, where people somehow don't seem to think of that when you make an image smaller - it can really fuck up the star trails.

Essentially destroying the overall impression of star trails.

I never thought it would be so fun (and interesting) to make star trails images. Given that the stars show up much stronger than anticipated... There aren't many stars I can see with my bare eyes, due to the glare of Stockholm city towards the North.

Yet, the stars spring out of the image very well.

Should work within the (bright) city, too

Imagine that in a darker environment. At the same time, I think that it is fully possible that when you go into the city, style some beautiful perspectives with the rooftops of Stockholm - combined with star trails above. I mean it should works, given that the stars pop out much more than your bare eyes can see!

But you've get to wait for one hour or so... for every single image. *gulp*

I believe that if there is a risk that the battery drains fast, that you can adapt an external battery via USB-C instead (or in addition). I have not tested that yet.

Honestly I was surprised that the battery went down so quickly. I thought i had at least 50% left (yet i hadn't checked it. I only made a few exposures last night in the kitchen - that was all). Perhaps the LCD screen, which i had folded out, might have drained the battery more than necessary ?

Right now, i am exposing a second image - at around 1+ hour exposure - without the LCD screen - and the IS turned off, with a fresh battery 90-95% capacity. In theory the battery should last longer now...

I have heard that you can do up to 3-3.5 hours star trail exposures with one full OM-1 battery. What i don't know is, if/what the photographers had enabled/disabled; such as IS and LCD screen.
