Nessun dark e flat o bias non sono ancora capace!! 5 scatti da 20 secondi iso 200 su montatura eq6 Primo esperimento di somma immagini,con il mio amico Joseph. anche se sono solo 5 scatti uniti. Scattata da un colle vicino a bergamo purtroppo mezza luna e inquinamento della città non mi ha permesso di fare meglio.

Here Andrew, what do you say?





Then I send you also the tiff is 80 MB. I used all 9 pictures you sent me. It's not much effort, I worked an hour, just to see what you could pull off the poses. The color balance is not good because I used the settings for my 500D modified, then I corrected a little 'later, but it would always be better to do it at the start. The alignment and compositing of the poses I did with Maxim DL, with the command SDmask, which is a bit like a 'more sophisticated media and in your case it was useful to remove a little' hot pixels, as there were no dark. After I moved in Photoshop, working on curves and levels progradually pulled out as much as possible. I noticed that in your pose is very banding, both horizontal and vertical, I do not know whether it is due to the lack of flat field or another, maybe someone can explain better than me. With the 500D I've ever had, even without the flat, maybe it depends on the sensor. However, I think with a more thorough job of my somewhat 'hasty you can eliminate this problem. The final image is off from 3 different elaborations of the initial image, one for the external parts, one for the heart of the nebula and another for the intermediate part, made of three layers and then joined. I applied unsharp mask only on certain areas and noise reduction on others, even if a little 'left of it. After I reduced a little 'stellar diameters, then I applied an S-curve on only the red channel to turn it up a bit' and at the same time lower indark tones to keep it out in the sky. Finally I gave a bit of saturation on everything and I cropped a bit 'to adjust the picture.
I hope you like it, however I think that there is an object on which the personal taste dell'astrofotografo affects as much as the M42, I have really seen all the colors!

hello

Clear

Definitely the work of Chiara was great, well-known lines vertically, but perhaps it is due from a few poses m42!
