Don't mind me, just some flerf that goes by ‪@BronekRossa‬ can't understand the phases of the moon even after being a flerf for at least 8 years. In this photo, the sun is clearly off to the left (as indicated by the shadow). So the left side of the can is lit up by the sun, and the right side is in shadow.

This is the equivalent of a "half moon".

I have a question for ‪@shanestpierre‬, ‪@space_audits‬, Heffron, or pretty much anyone from the Aether Cos crew.


The setup:



A while back, Dr Mike borrowed a proper theodolite (Sokkia brand?) from his brother-in-law, and measured the elevation angle to Pikes Peak from his house. The measurement was 2° 18', which was quite close to the globe prediction of 2° 19'.



So then he goes and sets it up for the evening's star occlusions, but instead of the SeeStar, he uses an *ABSURDLY* powerful telescope with a focal length of 6000 mm (for a lazy $600k USD, mind you). He has Pikes Peak in the perfect, dead centre of the frame, and he captures 39 Aqr being occluded.



The (first!) question:



AT. WHAT. ANGLE. is the telescope pointed? Leave a comment as to why you chose what you chose, pretty please.

It will forever be unbelievably hilarious to me that in attempt to clout chase from a bigger channel, ‪@NathanOakley1980‬ launched ‪@DaveMcKeegan‬ 's channel into orbit! 🤣🤣

I wonder if anyone can pinpoint when that happened based on the graphs below 🤔

Hey ‪@CrealityPodcast‬ !

"Mean Sea Level is *ALWAYS* the datum for your curve calculators"
(youtube.com/clip/Ugkxyhh0ra6r8v9UyOfh6h5yKikTQwBoe…)

Q1. If I'm Joshua Nowicki, on the shoreline of Lake Michigan looking across to Chicago, should I used 6 feet as the observer height? Or ~590 feet?

Q2. If I'm TFHM, and I'm say 3 feet above MSL, but 15 feet above the level of the water (because of low tide), what value should I put in the curve calculator?

Just a super quick post to ‪@BriansLogic‬ with a geogebra link that models the Blackpool Swan photo on flat earth and on a globe (both with and without refraction).

Should be pretty self explanatory: www.geogebra.org/calculator/u9u8q7dv

And yes, it is actually *TO* *SCALE* - I discovered that you can compress the axes visually! (Aren't you proud of me ‪@Petey194‬ !!!)
