Mars imaging through clingfilm
Pete Lawrence wrote:
Finally boil the image on high heat continuously throughout the session. Very frustrating indeed. The only results I got looked like someone had blasted the planet to smitherines when processed with Registax. I hope others are getting better skies. Very warm though. Perhaps I should have settled for a G&T and just admired the stars ;-) Very cloudy here - Mars burning through every now and then. I was too knackered to use the scope - 15x17 binos gave very clear views of the disc - the sharpest I've seen Mars yet - particularly at the moments when Mars was just appearing/disappearing. I'll try the neutral density filter next time out with the scope. Mars is definitely too bright for the binos - it seemed to shrink to a disc as it faded - there must be some kind of flaring in the optics.

Certain hazy conditions can improve the visibility of the planet by filtering out some of the excess light. However, in order to do this the haze layer needs to be pretty constant and of just the right type. Last night was full of variablity. Quite surprised how little drop off in intensity was needed to render the view through the camera invisible though. Bloody weather! -- Pete Homepage at http://www.pbl33.co.uk CCD/digicam astronomy |

The variability was certainly OK for my low mag visual - but a total nightmare for the imagers - my condolences. Cheers Martin -------------- Martin Frey N 51 02 E 0 47 -------------- |
