Sorry, RIGOL is the knock-off of Keysight (formerly Agilent, formerly Hewlett-Packard).

So that other one is a knock-off of a knock-off! :)

I've used a variety; the shadow of the secondary mirror can cause a bit of focusing confusion if you're not used to it. No DOF differences.

You might be out of luck - Sun Camera used to do it, but they don't do any film cameras anymore. Here are some ideas, in order of likelihood:
Halton Camera Exchange - Georgetown - Alex has a technician who does a fair bit of work, but may not be able to do the LX - https://www.haltoncamera.com/
Burlington Camera - Burlington - Joan is good to talk to and may have some advice - https://www.burlingtoncamera.com/
Bell Arte - Hamilton - They may have a name for a tech that can do it. https://bellarte.fotosource.com/
Downtown Camera - They might be able to refer you to whoever does theirs. https://downtowncamera.com/
Let us know who you find.

Turn the whole thing upside down, and the pin may come lose enough you can wiggle it off.

Lens heaters for Astrphotography?

You need to decide what the value of your lens/camera equipment is, and decide if its worth it. eg if it's a $1000 lens, spending 10% is reasonable in my books.
The problem is some of the knock offs are badly made, and will short out, aren't actually waterproof, and have hot-spots instead of the even heating strips Kendrick uses.
The hotspots can melt the plastic parts of the lens body.

Kendrick makes the best, hands down. I've tried others, and I always go back.
Kendrick Astro Instruments - dew removal, imaging power, power packs, observer tent, solar filters, focus masks, USB hub,cord management solutions
The Kendricks are fairly efficient, well constructed, they transfer just the right amount of heat, and the velcro/elastic helps you adjust it to any lens.
Anything else is a knock off.

Test it out on the stars on a still night. If the body has Live View, that's a good way to have a look.

Is this a brand new camera, or new to you?
Check if the firmware is current, and reset the camera.
Firmware: Software Downloads : Support & Service | RICOH IMAGING
What lens are you using? Is the lens auto-aperture, or manual? It could be failing to open the aperture if set wrong.

Nice series. Mind my asking how you scanned the negatives? Results are great.
I did chuckle over this at the top: Lens: -- Camera: Pentax 67 Photo Location: -- ISO: 204800 Shutter Speed: 1/8000s Aperture: F45
Must be a lot of work in the darkroom for that 400 to deliver those results!

Go somewhere dark, away from city lights, and give it a try. The sensor is quite good in your camera, so like AstroDave says, crank the ISO up a bit - I think you can shoot with 1600 no problem.
