OK class, Remember to remove your filters before packing up your equipment!
Or, with those bloodshot eyes, everything must look red....
Or, if it's a chrismas scope, you can remove the red wrapping paper from the OTA now...
Or, how do you not know it wasn't an airplane trying to shine a laser down your scope??
Or, We're fixing to be attaked by a giant white space pie....

However, I'm betting on atmospheric conditions.

For me, far more effective in the altering of perceived color purity is whether I'm dark adapted or not. As dark adaption proceeds, star colors become paler.
Additionally, when I see the redder stars in deep twilight, where the blue of the sky is still perceptible, they seem to be more intensely hued, presumably due to the effect of the complementary colors, blue and orange.

That's a nice image! It's been a while since I've fooled around with Celestia. Did you do this by setting the time forward, or by using some other function?

Perhaps you are wearing rose colored glasses? Have things generally been looking up these days?

It really did look redder the usual.

Lots of sucker holes ... And frustratingly decent seeing between them, too! If I didn't have a paper to type right now I'd be out there hunting for good views through them.

It is amazing to me that humans have not observed (not on record anyhow) any supernovas in the Milky Way since Kepler's SN over 400 years ago..
I hope Betelgeuse doesn't go SN anytime soon. It would ruin my Astrophotography for a long time!!!
(over three weeks of daytime visibility!)
(though I realize that a span of 400-500 years is but a blip on the radar screen of time in our Universe, relatively speaking)
Some cool reading here,

Hm, on a side note (these topics sometimes get my mind racing ), anyone else here wonder just what sort of stunning Planetary Nebula our beloved Sol might produce in several billion years time, and what distant life forms might perchance observe it? (Perhaps some of our ultra distant descendants might view it from afar, with wistful remembering gazes, or is that just ego talking? )

On another note this is a fun artist rendering of the Milky Way showing the most recent SN's and SNR at this link.
There is a very high and condense number of large stars in the core region. Undoubtfully there have been SN's there and on the opposite side of the galaxy that we simply cannot see. I would also think that before Betelgeuse goes SN, we will probably see a Type Ia (White Dwarf) SN since many of those are still unknown.
