Well, it's been a long time since there has been really good imaging night's as the sky hasn't really got dark but since the start of August we have been looking to the SE for our first sighting of Mars. We have found a new problem while imaging Mars - there is a lot of infrared light coming from Mars and this is making focusing and sharp images a problem. We haven't received our infrared filter as yet so we tried using a Broadband filter instead and this certainly brought out a lot more surface detail. Here is our latest efforts.
The image was taken approximately 18 miles South of Belfast in a very dark site and you can clearly see the benefits with the better contrast in the image.
We reprocessed our Mars avi in the new Registax version 2 beta and we produced a significantly better image. The new Registax can automatically compensate for Red shift and this resulted in a much sharper image.
Taken on the 19th August 2003 at 0104hrs using a Meade LX200 10" at f10 and a Philips TouCam Pro. Image aligned and stacked in Registax v.2 beta and edited in Paint shop Pro 8.
We are currently waiting on an IR Blocking filter which should help with the sharpness of the final image.
