Guest peter shah Posted November 29, 2013 Share Posted November 29, 2013 (edited) After a discussion in the chat room I've had a look at some of my really old images from when if first started imaging.....I first started taking pics of constellations 29years ago with a old Richo SLR then moved on to my first CCD camera about 18 years ago..... here is one of M31 taken on film manually guided for over an hour through an old SCT... probably the best film shot I ever did https://docs.google.com/file/d/0ByvDXZWAi3SvWmFxZnd4YnJKNWM/edit The Aurora over Birmingham i think in 1998 https://docs.google.com/file/d/0ByvDXZWAi3SvN1B4TUtIeld1M00/edit My first CCD image https://docs.google.com/file/d/0ByvDXZWAi3SvaEpILUY2VHhOTWM/edit and my second CCD image https://docs.google.com/file/d/0ByvDXZWAi3SveV80LXlDb2JJSUE/edit it would be nice to see some of your first shots too cheerspeter Edited November 29, 2013 by peter shah Link to comment Share on other sites More sharing options...
Guest foundaplanet Posted November 29, 2013 Share Posted November 29, 2013 That's real Interesting. I think the film shot is a goodun of M31, when I think of what I used to see in the old astro books that's not at all bad. Good to see the first ccd images, bet that was an exciting time, realising how much things were going to improve for the hobby. Bet you never imagined just how far you would end up being able to take it though.. Quite a ride you have been on.. Great post... Link to comment Share on other sites More sharing options...
T A WOW Posted November 30, 2013 Share Posted November 30, 2013 That M31 is incredible. Especially as it was manually guided! CCD's have deffinately come a long way. Bet if you could show your 1990's self your recent images his eyes would pop out! Link to comment Share on other sites More sharing options...
catman161 Posted November 30, 2013 Share Posted November 30, 2013 That's really interesting to see where you started Peter, thanks for that. How does one go about manually guiding? Do you mean that you manually slewed the scope inch by inch to keep it on target? Link to comment Share on other sites More sharing options...
Guest peter shah Posted November 30, 2013 Share Posted November 30, 2013 Thanks for the comments.....Manual guiding gave me a serious headache.....when I moved over to ccd it was just silly, that whole hour of exposure could be captured in about 30s...it really stunned me....I learned all about reciprocity failure and how emulsions react to long exposures while doing my photographic degree, so actually seeing the difference with something that doesn't suffer from it was incredible........

It really does Felix....especially when I remember my eyes watering and my eyelashes actually froze to the eyepiece....and knowing now the same amount of signal can be captured in only a few seconds....amazing really Edited November 30, 2013 by peter shah Link to comment Share on other sites More sharing options...
