Solar webcam - Sun in H-Alpha (http://www.djcash.demon.co.uk/astro/webcam/Solar.htm)
The following images of the Sun were taken with my Coronado Personal Solar Telescope (PST) using a Toucam Pro webcam. See also my CCD Solar images taken with a Starlight Xpress SXV-H9 CCD camera.

The following images of the Moon were taken (http://www.djcash.demon.co.uk/astro/webcam/moon.htm) at the Cassegrain focus of my Celestron Ultima 9.25 telescope without any additional amplification, using a Toucam Pro webcam. All images are stacks of individual frames, extracted and processed using Registax. An unsharp mask operation was carried out using PaintShop Pro. The seeing was too turbulent to use a barlow lens.

The Venus image (http://www.djcash.demon.co.uk/astro/webcam/venus.htm) was processed using an unsharp mask (strength 5) and the Lucy-Richardson algorithm (3 iterations). This image shows colour fringes due to atmospheric refraction.

The following Mars image (http://www.djcash.demon.co.uk/astro/webcam/Mars.htm) was acquired using my Celestron Ultima 9.25 with a Philips ToUCam Pro webcam. The seeing conditions were not too turbulent. A 2.5x TeleVue barlow and a Baader IR blocking filter were also employed. The image was generated from a stack of 3143 separate frames from 3 individual AVI files, and was processed using Registax 3.0. www.calsky.com was used to compute the simulation image.

The following Jupiter image (http://www.djcash.demon.co.uk/astro/webcam/jupiter.htm)was acquired using a Philips ToUCam Pro webcam in moderate seeing conditions. Each image was processed using Registax.

The Saturn image (http://www.djcash.demon.co.uk/astro/webcam/saturn.ht) below was acquired using a Philips ToUCam Pro webcam. It was processed using Registax 2 and Adobe Photoshop 7. The final image is a stack of 351 individual frames taken in good seeing conditions. A Baader IR blocking filter was used. This image is probably my best Saturn image to date.

The following Uranus (http://www.djcash.demon.co.uk/astro/webcam/uranus.htm) image was acquired at the Cassegrain focus of my Celestron Ultima 9.25 with a long exposure version of a Philips ToUCam Pro webcam (Steve Chambers modification). A TeleVue 2.5x barlow lens was used. The seeing conditions were not too turbulent. A Baader IR blocking filter was also employed. The image was generated from a stack of 40 separate frames, each of 2 seconds duration, acquired using K3CCDTools. A beta version of Registax 2.0 was used to process the final image.
