I used 2 programs, PIPP and RegiStax 6. I will try over the next day to find the YouTube video that showed how to use them. I need a refresher course. The stacking does add incredible detail.

Correction. The angular size decreases proportionally to 1/d (approximately). The area will follow 1/d^2 though.

It was correct. The number of photons going through the lens aperture falls off as 1/d^2 because the photon flux depends on a solid angle, not a 2D angle..

Yes it's mine, thanks!
For artistic/nightscape purposes 200mm is enough, I understood the atmospheric aberrations start playing at longer focal lengths, you telescope is >2000mm.
For my purposes nything longer than 200mm will probably be an overkill unless I wanted to reproduce something like this (in)famous Peter Lik's moon shot

When i look at the r5 price guessing on here and on dpreview, it makes me feel most people frequenting these sites are stills shooters (which makes sense). the r5's stills specs totally make it the ~$3.5k camera that seems to be the most commonly guessed. I'd guess that as well if only looking at the photo specs. BUT the video specs.... if its 4k120p full readout, or 8k30p properly (not burst, time lapse, etc) - hard to see it being even below $6k. So something has to give on the video specs, else the price will be alot higher than $3.5k unless canon is willing to undersell the value of the specs simply to regain the mirrorless FF market (which i feel it will do anyway).
The cheapest FF 8k camera is the Z cam e2f8 which is $6k USD, and doesn't include anything - no monitor/evf, no handle/grip, no battery, etc. It's $7-8k+ just to hit the record button. The next cheapest FF 8k camera is red's monstro which cost $54.5k USD just for the brain - it's anohter $10k+ just to hit the record button. Granted, the red is very expensive for alot of other reasons than these type of specs, but just saying as a frame of reference how groundbrekaing the r5 would be if true. As far as I know, the Canon R5 will be the third FF 8k camera in the world under $75k USD?
Even if 8k is just a burst mode, and the highest resolution codec is 6k, there's a huge group of people that would think $5k+ is perfectly fair (cheap even) for 6k30p w/ DPAF. Video specs cost money. And plenty pay a huge premium for video specs - it's still a rapidly developing market whereas stills has matured.
My guess is 8k is a burst or timelapse mode, and we end up with 6k or 4k full sensor width readout as the max video resolution. and the 60p is super35, and the 120p is 2-3x crop factor. Canon must feel it needs to hit a price that caters to the stills shooters that have been waiting for a better R. I always believe CR is correct, so guessing the video specs will have a bunch of catches to them.

They'll come back on top soon....I think so for two reasons:
1. 5dM4->R5 migration alone will do it....
2. Sony ignoring video shooters. They forget how important this segment is....

I'm on a a7riv waiitng for an EOS R update with good video so I can have a real hybrid camera and not need 3 bodies (go down to 2). I really dislike Sony ergonomics and color (eyeAF and DR holding me out), and I've owned quite a few models. So have been waiting, and waiting, and waiting, for something like the R5 to show up. Very excited. Not fussy whether it has a AA fliter or not. Prefer it for video, prefer not having it for stills. Can't be fussed.

Crippled is popular word among those that don't understand the first thing about business or are just Sony trolls. Sony does indeed offer a very affordable FF camera. But it comes at a cost. Weather sealing is an industry worst based on testing. Dust removal system is very poor based on many reviews. Ergonomics are awful and apparently - despite user complaints for years - is not worth spending money on improving. Exposure metering is poor based on my own experience. I have read numerous comments from photographers that they have to buy multiple copoes of their lenses until they get one that isn't very decentered.
Having specs does not mean that they are well done specs. The only thing Sony does well is sensors and eye focus AF. They may have all the specs, but those specs are far more "crippled" than Canon's, based on my experience.

RP got auto stacking for lowering noise.
Btw would be cool if you could connect many camera together to shoot same sky view same time,their ibises could fine align shots.
