Diary of a nature photographer
Study, monitoring, research and photography about the Nature


IC434 also known as Horse nebulae, is really hard to take, mostly inside a town where the light pollution cut much light coming from stars, galaxies and, of course, nebulas. I should buy a light-filter-pollution to prevent this problem, but it's quite expensive, so I'll wait until I'll have enough money.

In this last work, I should have learned some important things. First of all, don't change the ASI Air guide parameters so strongly. Using these settings:


I got this guide-graph:


that is pretty good for that night, where sometimes it was slightly windy and with a Bortle scale of 8. After a couple of hours of work, getting a lot of cold, I caught this image:

that is the sum of 49 light frames, 10 bias frames and 9 dark frames. For the image stacking and elaboration, I've used Pixinsight, in a trial version for now, but I hope to buy it really soon, making the last final retouch with Adobe Photoshop. I know that the final image isn't so good. I know there's some problem with the stars in the left up and right low corners, but I can't figure out why. Then there's always the moisture problem that I hope to solve with my home-made dew heating band, that I'll try it next time.

As always write to me if you want for some advice or anything.
