Makes me hungry. Good custard is hard to find where I live. I grew up in Milwaukee and we had the best. Lovely processing here!

Joel,
Their orange sherbert and vanilla ice cream twist was delicious!
The image was made a week ago in Mays Landing, NJ.
Thank you for liking it!!

I hesitated to put this astro image up as it is well and truly outside the normal square for this thread. On the other hand, it demonstrates the capability of medium format in this space. I took it when I had opportunity to stay overnight at a dark-sky location in inland Canterbury, and decided to take my star tracker and test how my new-to-me GFX 100S would perform on a deep space target. This was taken with a Mamiya RZ Apo Sekor 210/4.5, which I find adapts very well for astro. What surprised me here was that I had opened the aperture up fully to focus but then failed to stop it down to my usual F/5.6 before taking a sequence of shots - so this is shot wide open. The image is a composite of 20 60-second images shot at ISO 640, processed in PixInsight with final adjustment in PS. The target is the Large Magellanic Cloud (LMC) a satellite galaxy of the Milky Way, so called because Magellan was the first European to venture south of the equator in 1519, bringing the attention of the LMC to western astronomers, although it was well known to many southern hemisphere cultures. Apologies to you northerners - you will have to come south to see it. Here in NZ, it is clearly visible with the naked eye.

Are you working with any software before PixInsight or just using interval shooting directly in camera? Wondering if you're using FITs or the Fuji raw files in PI. Had a lot of issues with some photographic camera raw files in PixInsight before, but not familiar enough with Fuji raw files to know if theres any hassle.

Chris, I find it straightforward to work directly with the Fuji raw files in PI, and have a library of bias, dark and flat frames, following the usual PI process of calibrating, debayering, aligning and integrating images.

Ah thank you! My issues were mainly with Nikon mirrorless raw files. Haven't even thought about trying to use Hasselblad's raws but may be overthinking that one.

John,

WHAT A SHOT! Fantastic!

That must be the best photograph I've ever seen of the LMC.
