Stars Go Zoom!
Lens: Tamron 500mm f/8 mirror Camera: K-5iis Photo Location: Blue Mound State Park, WI ISO: 1600 Shutter Speed: Above 6s Aperture: F8

Sometimes sharing your fails can be good too. Here, I was using an iOptron SkyTracker mount to shoot the Horsehead and Flame Nebulae with my Tamron. That's pushing the limits of that mount pretty hard to begin with, but this frame shows an added challenge: The batteries died partway through the exposure (which was likely around a minute, the EXIF data don't include the exposure time). So the dim nebulae are relatively sharp, but when the apparent sidereal motion took off, the stars were bright enough to expose long trails.

I swear on my honor as a Pentaxian that this is a single exposure, NOT a double exposure or composite of any kind.

Warp speed, Mr. Sulu!

This looks like the Star Wars fleet has just switched to light speed to escape the bad guys.

Gotta love astrophotography. It can go sideways so quickly! My HEQ5Pro was giving me many problems this past winter. I plan to upgrade it to a belt drive in the fall here and hope that helps solve them. I also fine tuned the worm gear as there was quite a bit of backlash.
