But I do not like it very much: it has enormous potential but in my opinion there is too much difference in processing between the central bands and the outside parts, personal taste I would equilibrate the processing of the two parts.

WOW ... beautiful picture and very rich in dittagli. Sign of a set and stationary made at the rule of art.
Photos of M31 are seen as few.

Hi gianluca ... regarding your comment ... it is always subjective in an image if the dust bands stand out compared to other structures of the Galaxy ... In this image, however, there are structures that in themselves are more evident just like the dusty areas around the bulge ... The beauty of astronomy is that the processing suffers from what the subjectively every astrofotografo wants to get ...
however briefly I am in a position to review this image further enhancing the outer areas of the Galaxy .....

Sure Stefano, in fact I speak for personal taste, given the abundance of signal in the photo I would also balance the outside parts, but since you have in mind to do so I will wait for that version ;-)

Hello Stefano, can you explain how you can do all your work without self-guidance? Maybe with so many short exposure shots under a perfect sky? Thank you very much

Hello Riccardo use as a frame the GM1000 HPS company 10Micron, I use a software that thanks to Active Encoder allows you to maintain the position in the sky within a range of < 1 "for about ten minutes for which the Autoguida is no longer needed!
The latest version also has the built-in dithering, the mapping of the main lunar subjects, in addition to tracking the satellites once the orbital parameters have been inserted.
The only thing the user has to do to achieve such performance is to make a good mapping of at least twenty stars of reference to create the astrometric model.

I take advantage of your patience! I would like to know how you solved the problem of feeding the equipment at height (battery with inverter, generator set, refuge with current?) I read that the shooting you made from the hill of Nivolet, thanks a lot, hello

hello Riccardo for power I use a 40 ah agm battery that lasts a couple of nights more than enough for itinerant use if necessary then to use for several nights recharge in the hotel, ditto for charging batteries for power room Canon EOS .
