And here's the last shot .. the summer evening had started badly, a lot of moisture had moved my interest in this subject and then to the stellar mass very scenic.
The recovery started at 1: 30 and ended at 3:15 and I set the recovery on the histogram of the early evening, then the time has gradually improved together with the wane of the moon, darkening the sky background and bringing the ' histogram to the left. In phase I
processing then saved only 15 poses to the exclusion of many, even slightly moves, most all shooting in the first part of the evening.

The end of the holiday is approaching and it was really good last night for shooting, moisture, light wind.
The subject is the constellation
galaxy M33: Triangulum
Size: 68.7 'x 41.6 '
Magnitude: 5.70
Surface Brightness: 14.20
very beautiful object: a galaxy brazenly showing its spirals.
Along the arms, there are several nebulae, which are highlighted in the second half .. but no sign of a lack of sensitivity to red, but of inexperience in processing.
The shot was made from 1: 00 to 3:30 with

with Iris Iris and NeatImage
two different versions even in color balance, to more questionable for both.
The first report was made to extract as many details in the central area but did not lead to saturated star or galaxy, the second highlights maggiormante arms but saturates the core and the stars.




raw Unfortunately the trial version of Neat Image can only save JPG, the use of the program has cleaned up the bottom, but worse on the subject.
E 'have a gradient on the bottom that IRIS was unable to delete.

continue with the tests and summer pictures ...
With the choice of this nebula I wanted to test the sensitivity in the red machine Eos1000D not changed. The subject
the nebula IC1318 is a portion of the large emission nebula in the constellation Cygnus. The nebula itself is crossed by a dark nebula LDN899 . The presence of Sadr is a perspective effect.
The choice of frame is not the best and loses part of the nebula.
The shot was made from 2 to 4 with

afternoon after a long reflection on the subject of shooting I choose this galaxy for two reasons ... because I saw it and why it is in an area very rich in galaxies. In addition NGC7331, main subject in the frame will many other small galaxies, among them also Stephan's Quintet. The subjects are very weak and deserve a more dark sky .. ... and many many poses even more experience ....
