I'm a little late with this, but R.I.P. Tom Matano, father of the Miata (MX-5). My Miata is nearly identical to the one he's standing next to in this picture. I've owned a red NA since 1990 (when they first came out). Tom gave joy to so many people. www.caranddriver.com/news/a680045...

Thanks @developers.google.com, @microsoft.com, Amazon, Apple, etc. Are you also going to pay to fix it when the tyrant is out?

That's "millions," you idiots. The Time's coverage of yesterday's protests is shameful. I've subscribed since 1978, but I'm close to cancelling. I'll keep my subscription to their puzzles, but it's a tragedy. Our nation's greatest newspaper is reduced to a niche supplier of amusements.

For your amusement, here's the stack that was processed to make the previous version, auto-stretched and rendered by AsiFitsView at 3 resolutions: about 1900x1900, about 2K x 2K, and 1:1 (partial image). Just look at the artifacts (which I take to be Moirés).

Here's a reprocessing, followed by 2048x2048 resampling as part of export to JPEG. I believe this should eliminate all of the artifacts.

Hey @developers.google.com, you're making me cope with this annoyance with alarming frequency. You know and I know that uBlock Origin is the single most useful Chrome extension ever written. When I can no longer use it, I'll no longer use Chrome.

Here's the Triangulum galaxy (240 1-minute exposures stacked) from my light-polluted San Jose backyard. This one would really benefit from a darker site, and I hope to try it soon. The spiral arms are much larger than they appear in this image, and the galaxy has beautiful red star-forming regions.

Here's four hours of the Pleiades, captured, as usual, from my backyard. I'm hoping to go to a darker sky site (Fremont Peak) soon.

BTW, I'm not getting this quality guiding out of my Celestron AVX mount (.52" RMS error). It may even improve a bit more as I try to eliminate the stiction that I introduced while reducing the backlash. (Of course the error is worse when I'm guiding my 8" cat with OAG, but still decent.)

I took this image of the Fireworks galaxy (NGC 6946) two nights ago from my San Jose backyard. The bright moon coupled with iffy skies limit the detail and signal-to-noise ratio, but still, it made me smile.
