Venus visits the Sun from my front yard.

My first attempt at Astro photography before I go out and spend more money.

Mosaic of 30sec exposures I took to locate Neptune, using Venus as a starting point.

Good seeing once again. Video frames stacked and processed with RegiStax.

Meade ED 127 refractor telescope, Meade 5x Barlow lens and Philips SPC 900NC webcam. A video clip was taken and the best frames processed in Registax 5.0 software to produce the final bitmap.

Image taken with an 8" F/6 Newtonian and 2.5X barlow. About 1200 frames stacked and processed with AVIStack. Back in the days of film, I would have been delighted with the upper image.

The milky way taken over north yorkshire last night.

No jet stream tonight but very breezy. Celestron U2K, 2x barlow, prime focus, Logitech Quickcam and Registax. I left the dew shield off the telescope because of the wind. One of these nights I am going to end up with perfect conditions, I just know it.
