It should be mentioned that many constellations are made up of stars that are nowhere near each other, except from our perspective.
Yes, good to note for those unfamiliar with the subject: The LOWER the magnitude number, the BRIGHTER the objects. The brighter magnitudes have NEGATIVE signs. i.e., a minus 3 is brighter than a minus 1. A minus 1 is brighter than a 1. A 1 is brighter than a 3. Minus 1 to minus 3.5 ISS passes are very bright and easy to see with the naked eye.
I intentionally stayed away from Iridium Flares. Way too difficult to explain how to see them from so many different locations as we have represented here. They are precise down to the second for a very narrow set of locations. They basically are mirror-like sun reflections beaming off antenna panels of one of the 60 or so Iridium satellites orbiting the Earth. They can get as bright as -8!
Yes, that’s true of constellations and many other background stars. An intrinsically brighter star farther away can have the same apparent brightness as a dimmer one much closer to home.
Thanks for the link. Going to try it!
You’re welcome. If you have any questions, feel free to post them here. I should be around most of the day.
Wow! Awesome picture!
Just took a look at my location - no Iridium flares tonight, but I will have a nice view of the ISS.
I had the Nikon f2.0 135mm lens once. probably the best lens I ever had, dont know why I sold it.
Their f2.8 80-200mm zoom lens is overrated IMO.
