parklife2uk Posted March 17, 2014 Share Posted March 17, 2014 Whilst my daughter was using the scope last week to observe Jupiter I decided to take some shots of Orion with the DSLR and was quite surprised with the results! Have a long way to go though...!! Link to comment Share on other sites More sharing options...
Johnnyaardvark Posted March 18, 2014 Share Posted March 18, 2014 Nice. Starting to get some detail on the M42 there. Judging by the constant width of trace on your visitor it look like a satellite. Link to comment Share on other sites More sharing options...
dawson Posted March 18, 2014 Share Posted March 18, 2014 Cool. Yes, can certainly make out the bat-like appearance of M42. How long was the exposure, and on what mount (just a static tripod)? and at what focal length was the lens set at, 100mm? 200mm? ISO? It's a good start. You could do a load of those from a static mount, and stack them, and see what extra detail you bring out. Here is an example of what someone has achieved without a tracking mount or a telescope: http://www.flickr.com/photos/latent0image/6866355961/ But lovely image, and it's always rewarding to see something which reflects what you've seen in the books or on proper imagers postings.

parklife2uk Posted March 24, 2014 Author Share Posted March 24, 2014 Thanks guys. Image details are f/5.6 5sec exp, ISO-1600 250mm focal length. Was taken on a static tripod as I do not yet have a tracking mount - that will be my first purchase after my wedding... What software do you recommend to stack with?

dawson Posted March 24, 2014 Share Posted March 24, 2014 Most people seem to use DSS (deep sky stacker), but i've only used it a handful of times. There are probably other free softwares out there and ones you could pay for too. See if the clever DSO imagers have any suggestions. I remember reading about stepping a lens down a few steps from its maximum aperture to reduce coma aberration. There looks to be some artefact on your stars, which could be vibration from you or the mirror or an issue with the optics (i think less likely as it seems to be across the whole frame); but worth considering getting some form of shutter release cable/wireless device, or controlling the camera from a computer, and thinking about licking the mirror up to limit vibration, and experimenting with different f/ values and duration of exposure... It's fun messing around with this sort of stuff. Jd Link to comment Share on other sites More sharing options...
parklife2uk Posted March 28, 2014 Author Share Posted March 28, 2014 Thanks James - I've downloaded DSS, but can't seem to get it to work properly. You're right though - it's a lot of fun!! Link to comment Share on other sites More sharing options...
+RonC Posted March 28, 2014 Share Posted March 28, 2014 Make sure it's v3.3.3 beta 47 , that works a treat Steve Link to comment Share on other sites More sharing options...
parklife2uk Posted March 28, 2014 Author Share Posted March 28, 2014 Thanks Ron, I was using v3.3.2 but now I'm using v3.3.4 but I get the same results I can't seem to get it to stack upon the same alignment. Each shot is slightly different as I couldn't/didn't track the nebula. So I'm not sure how to stack correctly if I don't track. Confused? I am..!!
