Mars 2003 Jul 28
Had another go this morning; the sky was getting a bit bright by 04.45,
which is when I began imaging, hence the blue background to the image, but I'm getting more pleased with the results I'm getting (not up to Pete's standard, though!): http://www.astunit.com/tonkinsastro/planets/mars.htm Best, Stephen -- + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + Stephen Tonkin | ATM Resources; Astro-Tutorials; Astro Books + + (N51.162 E0.995) | http://www.astunit.com + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + |

In article , burbled
happily... Had another go this morning; the sky was getting a bit bright by 04.45, which is when I began imaging, hence the blue background to the image, but I'm getting more pleased with the results I'm getting (not up to Pete's standard, though!): http://www.astunit.com/tonkinsastro/planets/mars.htm Rather good again. I must have a go at building an adaptor similar to the one you've done, looks to be doing the job quite nicely. -- Craig Oldfield |

Not putting down your earlier images but, what an improvement. Well done that man! Conditions were quite nice for me last night too (no cloud to start with and only a F5 gale blowing!). I was too tired to process when I'd finished, but initial looks seem encouraging. My digicam can only manage 320x240 in movie mode so I tried a Registax ( 640x480 ) friendly manual movie simulation - basically firing the shutter off for 100 images in succession. I'll deal with those later though. Any kind soul like to help out a tired brain (trying desperately to cope with Monday morning at work ) and tell me what sort of timescale I'm looking at before planet rotation becomes a problem? -- Pete Homepage at http://www.pbl33.co.uk CCD/digicam astronomy |

(http://www.pbl33.co.uk/) -- and there's better to come.... Ah -- but his "only a 4 inch" is a Vixen reflactor. I suspect that has advantages over a 5" SCT with obstruction. But we will wait for Stephen's future results to prove me wrong :-) I hope they do, since I'm about to travel the same path - using the the same scope as Stephen coupled to a camera identical to Pete's. It is interesting that Pete and Stephen are posting good shots from the UK (not noted for clear skies) and Eric Ng is doing great stuff in Hong Kong with a 10" R-C as I recall (and Hong Kong does not seem among the best of sites for astrophotography).

... reflactor Wouldn't that be the same thing as a catadioptric? (I love that slip, it's perfect. g) |
