'scope is increasingly looking like an improvised "device".
And the dew heater ring in the flat panel cover got a teeny bit too toasty last night. Need to dial that down a bit, and reprint it in ASA instead of PLA.

You don't just take a single photo of the moon. You take a video then stack the best frames to try to eliminate atmospheric distortion.
I took 3min videos, which was about 20gb, then stack the top 20%. Do that for all 4 LRGB filters (sane people use a colour camera).
Then sharpen and combine

It's mainly to visually monitor the telescope (the top of the mount is in the bottom right) and checking for clouds. But I hope to get it working as a safety monitor that can link up with the scopes PC to automatically close the cover in case of clouds/rain.

Me: Finally! After weeks of cloud, a clear night to do some deep sky imag....
Full Moon: NOOOOPE!
So I guess I'll trying capturing the moon for the first time instead.

Now to get the flat panel to work, as the original creator of this driver/board, Dark Sky Geek, didn't make it as a dimmable light but just an on/off spectral calibrator.

I could then layer that on top of the main character texture with an unlit shader, so it appears similar to the other flames in the game.
That to me is the brute force dumbness; an entire texture the same size as the primary with just 3 little flames on it.

I wrote a simple scriptable render feature to temporarily divert the rendering destination, from the camera's main render texture, to a separate render texture when drawing transparent objects (the sprites)
This gives me a texture with just the (correctly occluded) flames.

The flames on the player's candelabra are those same sprites tacked on to the 3D model, which ended up being handy as it meant they were being rendered at a different point in the camera's render pipeline than the 3D geometry.

but this means that the flames of the candles would also affected by that lighting system and not appear as bright light sources on their own, like other instances of flames, which are just sprite animations with an unlit shader.
Although black flames are creepy in their own way.

I also captured some of the Horsehead and Flame nebulae on friday, but the data is pretty trash. I don't have the best view of it, it's pretty close to rooftops not to mention wires and a tree. Maybe 3 hrs on it after throwing out the worst frames, so just did a speed run (over)processing

The Elephant Trunk Nebula IC 1396
I captured just Ha and SII on first night, due to moon being a bit too bright for OIII. Had to wait ten days to capture some OIII (blue) on Friday, the single night it'd been clear since.

Not sure if I'm happy with this. at the point of just poking at sliders and probably just making things worse if I look too closely at it.

For the past year I've been building up an astrophotography rig.
Clear nights are few and far between here, but I managed to get a full session in last night for the first time and had a first go a processing the images.
This is the Pacman Nebula (NGC 281), in the Hubble palette.
