Starship Asterisk*

Chris, Atmospheric dispersion causes the chromatic fringing as you describe above. However, a flash is the refracted/broken/distorted/separated image of the fringe- which you got close to saying above. A "flash" therefore does not need to be above the horizon while the fringe/rim of the so...

Heart of the Scorpion Here is one of the most glorious spectacles of the sky- the region near Antares, Rho Ophiuchi and beyond: https://www.adamblockphotos.com/antares-and-rho-ophiuchi.html This is a 3 frame mosaic because I guess I could not stop but the image below is only the bottom. It is such ...

Hi all, It does not appear my astrophotography shows up on this list anymore. I will try to manually post some... Here is my latest piece of work: The Realm of Orion: From Mintaka to M42 Complex Information on the image (and FULL resolution) https://www.adamblockphotos.com/ic434-and-m42.html Copyrig...

Very nice... star colors are great.

Very good question.

The pits remind me of snow in grass or small thin plants that stick up. When the sun comes out- each stem develops a pit/hole surrounding it due to slight extra warmth the planet gained from the sunlight due to the difference in albedo (being darker than the snow). So... maybe there are small slight...

HI Geckzilla, I am not certain what is scattering the extra light. I will need to check out the secondary mirror supports and see if there is a wire or something peeking out causing the extra spikes. It is certainly something new in the optical path I need to track down. I hope it does not deter fro...

Thanks! Yes, I understand. The comment was with respect to images published here in the discussion groups (observation deck) for the latest images or like at the beginning of this thread.

Hi Guys, Thanks for checking out the latest image(s)! Concerning the sizes... unfortunately the website I use creates a temporary resized image that is not the one I really wish to be displayed/published (it is generally too small). So when you visit the page http://skycenter.arizona.edu/gallery/Gal...

Hi Ann,

Not many visitors are seeing this page... but I did- and I want to thank you very much for your continued support of my efforts. It is greatly appreciated and very rewarding.

Not to be too clever, but the Schulman Telescope is the largest telescope in the Southwest dedicated to offering public outreach programs (and generating pictures like these). With its large aperture and big CCD camera (with greater sensitivity) I would argue that the number of galaxies in my recent...

Thanks Ann. Please do refer to the most recent gallery of images I am producing at the Mount Lemmon SkyCenter (http://Skycenter.arizona.edu). Galaxies, for example, can be found here: http://www.caelumobservatory.com/gallery/galaxies.shtml or here http://skycenter.arizona.edu/gallery/galaxies Hopefu...

I love Adam Block's image of Arp 178. What a quartet, no, what a quintet of galaxies and what a fantastic "centerpiece"! What an extremely fascinating image, Adam! Ann Thanks Ann. I really appreciate that you took note of this image. I was not able to find many high resolution color (RGB)...

Adam, I just love your picture of NGC 3938! This galaxy is one of the "textbook-magnificent" face-on spirals, but it is too rarely photographed. You do it splendid justice with your fine resolution of it and your wonderfully rich palette of colors! :D :D :D :D :D Ann Thank you Ann. In ter...
