Are two nebulas not too bright, then considered the timing and little integration is already an advantage taking them with this kind of focus and bright lens as your Zeiss Planar. The only flaw is the post production in which dominates the gradient purple, if you have the RAW files you review the elaborazione- The other night I tried myself with a large field the same quadrant of the sky to 17mm, but my 450D Baader after having juice on M8 with 100mm and despite the SQM at 21:22, started producing thermal noise unbearable ... unfortunately I have no cooling system, whereas these days we have far exceeded even the 35th day and 28 ° night, temperatures that conflict with the SLR noisy as mine ... the only solution would be a very expensive SLR CentralDS but it is only a matter of wallet. Also I amlearning here in JuzaPhoto, everything I learned was about the friends who helped me with the advice and moral support in this difficult path.

Hello Beppe, having a room changed in reality 'these two nebulae appear quickly even with not very long time! Wishing I made many more 'frame on the same night but here I held only 3 to 10 minutes' cause I was impressed that despite the 10 minutes of exposure and ISO 1600 sensor was yes and no goal' histogram! I did a rework from jpg I had loaded abbastando the blue channel. To cool the SLR using a simple fan pc (FLX Noctua NF-A8) on a medium that made me a friend aluminum. This method and 'the most' simple set to pause between shots and the other a bit 'works, especially' cause where I photographed there were about 17 degrees and it was good with the thermal shirt and sweatshirt on him! However apart from the central DS I think the difference is even make plans for the elaborfinal action! Thanks again for the comment.
