![]() The one below can do things an unmodified DSLR cannot, and by the If that were true all of the astro folks would be Here is a gallery of the sort of thing that people are doing with their SCT telescopes these days using Hyperstar, sometimes on their first night out: Even a modest astro CCD like the one below can do things an unmodified DSLR cannot, and by the time you modify the DSLR for proper astro use you might as well just buy the proper gear in the first place (such as the camera above). If that were true all of the astro folks would be shooting with DSLRs but they're not. You are better off with a DSLR than a cheap colour astronomical CCD camera. FINALLY a high rez (and large) chip at a normal-human being price. Quality dichroic filters and a filter wheel, about $1000.00. I'm thinking of having an E-500 done if I can find a place that will do it.ĭedicated, cooled CCDs are good, but resolution costs a fortune,Ībout $4000 for 6-8 megapixels, more for higher. The people getting the best results are often folks who have converted a 350D or D40 for astro imaging (Canon actually made an astro DSLR called the 20Da) with a different filter glass in front of the chip. Now if you do get a tracking mount you'll be able to do long exposures and stack those as well and it just starts to open up a world of opportunities but do bear in mind that all of the filters stacked in front of a DSLR's CCD or MOS chip really put the hurt on deep sky imaging. Those are just wags and not to taken as "use these settings"! I'm just saying that it IS possible and I have seen a fellow over on the other forum who does some great stuff down in NZ with an E-500. ![]() ![]() ![]() With stacking you can keep your exposure to about 15 seconds and that will keep the star trails to a minimum without a tracking mount (they'll look mostly like points) and with stacking you'll even be able to use a higher iso like perhaps 400 (no higher though) if you stack at least ten or so shots (the stacking will remove a great deal of the noise). That to maximise the effect you need to stack images. ![]()
