Default Cosmos 2369 Rocket body passes Megrez

Hi guys – here is an image I captured on May 5th at 9:32 p.m. PDT (California, -7:00 hours UTC) of Cosmos 2369 rocket body as it passed through the Big Dipper, in particular, close to the star Megrez (delta Ursae Majoris), a visual Magnitude 3.32 star. Image details: Meade Series 5000 80mm APO refractor with a Canon 20D mounted in prime focus configuration on a Losmandy G-11 Gemini mount, 30-second exposure at ISO 800, Tungsten white balance. Remote, programmable shutter release, no mirror lock-up used.

This is a crop from one single, original out-of-the-camera shot; the vertical dimension remaining after the crop was the original, full height of the image, but the sides of the image were cropped to end up with a 4x6” final image. The outer parts of the original image seemed boring and lacked much detail (as well as having a problem with vignetting), so they were discarded before the text frame was added. I still ended up with vignetting, but it’s not too visible if you have a dim monitor.

Questions, comments and critiques welcome!

Clear skies!

Paul
