Re: APOD: The Pencil Nebula Supernova Shock Wave (2024 Feb 23)

Yeah. I blind solved the images at astrometry.net, saved the solved FITS files it generates, open them in PixInsight and fully solve them there (which very accurately incorporates a distortion model), and then use a tool designed to align images for the purpose of creating a mosaic... which is sort...

Re: Merry Christmas, Orin!

I will miss Orin's presence in the APOD threads. I enjoyed his posts and his love of cats. He seemed to always enjoy finding the cat picture that is often included as one of the links in each APOD.

I will miss you Orin.

Re: APOD: Northern Lights over Southern Europe (2023 Apr 25)

I think today's APOD is a very beautiful image. I like the colors and the fact that the light parts are not too bright and the dark parts are not too dark (I think there's a term for that but I can't remember it at the moment). It seems to be perfectly balanced to my non-photographer eyes.

Thank you Cousin Ricky, Eclectic Man, and johnnydeep. I enjoyed your posts and learned things I wasn't aware of before.

Re: APOD: Reflections on the 1970s (2023 Feb 02)

Speaking of astronomers ignoring the 1970s, I'd be more interested to see where NGC 1976 is? It is the year I graduated from high school, and it was also a bicentennial year in the USA. What is the reason that 1975 and 1977 got a reflection nebulae but why was 1976 ignored? NGC 1976 is the Orion Ne...

Re: APOD: Leonid Meteors Through Orion (2022 Nov 28)

Yes, the Leonids stormed in 1999, with rates as high as several thousand an hour. This shower is caused by debris from Comet Tempel-Tuttle, which has a 33-year period. Near perihelion it releases a lot of debris, so we tend to see high activity every 33 years, coinciding with this. Activity is like...
