Starship Asterisk*

The "above long-exposure" link in the description is to a different picture with a different scope by a different person.

Fair enough, but if no one is going to put forth the effort to spellcheck a single paragraph, expect criticism. I appreciate the effort required for two people to do this in their spare time. Thanks for pointing that out. I don't expect to influence anyone regarding image content; it's clearly a los...

Does no one proofread APOD anymore? There are three grammatical errors in the last seven days. One could be fixed using spell check. NASA wants to put humans on Mars in 20 years but is apparently unfamiliar with the fact that we have reached a level of technological advancement as a species that all...

Yes, well, some other details left out or wrong entirely: First, I'd like to buy a vowel... it's PAIRITEL, not PAIRTEL. Also, it turns out Arizona is not New Mexico. Very similar, yes, but not actually the same state... PAIRITEL is on Mt. Hopkins, south of Tucson, AZ. I'll give you "PAIRTEL&quo...

And a bonus owl silhou...

Carina Nebula Mosaic http://www.darkskyimages.com Copyright: Scott Tucker http://darkskyimages.com/images/EtaCarinaMosaic.jpg One more highlight from Chile: a 3x3 mosaic of the Carina Nebula. Only had time for hydrogen-alpha, but the detail still amazes me. Fun to peruse the full-resolution version...

Tarantula Nebula in Narrowband http://www.darkskyimages.com Copyright: Scott Tucker http://darkskyimages.com/images/NGC2070.jpg Just back from a week of spectacular nights in San Pedro de Atacama, Chile. Wow, those So-Hemmers have it made! We miss out on some truly unbelievable stuff, my northern f...

The Tadpole Nebula http://www.darkskyimages.com Copyright: Scott Tucker & Gil Esquerdo http://darkskyimages.com/images/IC410_STGE.jpg Wow, two good nights in one month! Here is a two-telescope combo of IC410 in Auriga. Luminance and H-alpha data with a Hyperion 12.5" at f/6.1 by me and RGB...

NGC2403 http://www.darkskyimages.com Copyright: Scott Tucker & Gil Esquerdo http://darkskyimages.com/images/NGC2403.jpg Spiral galaxy NGC2403 imaged earlier this week. Data combined from two telescopes: Luminance and H-Alpha from Hyperion 12.5" f/8 and RGB data from a HyperStar-equipped C1...

IC342 http://www.darkskyimages.com Copyright: Scott Tucker http://darkskyimages.com/images/IC342.jpg I shot this galaxy last weekend but clouds kept me from getting RGB data to go with my luminance and h-alpha filtered data. But my friend Gil Esquerdo had RGB data from 2 years ago, so I figured I'd...

Annular Eclipse Over Zion Canyon http://www.darkskyimages.com Copyright: Scott Tucker http://darkskyimages.com/images/EclipseOverZion_Small.jpg Finally had a chance to really go through my annular eclipse photos and have one in particular I'm quite happy with. We drove from Tucson, AZ, to Zion Nati...

Manfred, I bet it is a diffraction spike from 2nd magnitude Phecda in the Big Dipper. It is right next to M109, just outside your field of view. I bet it is beyond the camera's field of view, but still within what the scope can effectively see. A 2nd mag star would make a pretty huge diffraction spi...

I haven't used the program Registar in a while, but as I recall, it counts the total number of stars it finds when it finds points in an image for alignment. I don't know what algorithm it uses to determine what is a star and what isn't. You would want to use a dark-subtracted image to eliminate hot...
