Konihlav Posted October 13, 2014 Report Share Posted October 13, 2014 with DSLR it is a "miracle" that is possible to accomplish due to the fact that (i) you have a fast astrograph and that (ii) (at least) this object is kind of the very bright ones :-) anyway the 15min subs are amazing with DSLR, I checked your single subs per filter...

tommy_h Posted October 14, 2014 Author Report Share Posted October 14, 2014 Hi Pavel Thank you for your comment. It's right, the brightness of the object and the fast astrograph makes it easier. But the really improvement of making narrow band images with a DSLR is the removed bayer-matrix of my 500D. Thomas Link to comment Share on other sites More sharing options...

tommy_h Posted October 18, 2014 Author Report Share Posted October 18, 2014 Thank you, Antonio Yes, I scraped off the Bayer-Matrix with a wooden stick. The only disadvantage is that also the microlenses disappear. Thomas Link to comment Share on other sites More sharing options...
