Yes, that’s a processing choice to focus on nebulae.

Thanks for your comment.

I would like to share with you a very special project, my deepest image to the date. This image, with a total integration time of more than 170 hours, is the result of the work I’ve been doing during the last 4 years. All this time I’ve been capturing several images of the Cygnus constellation at di...

I would like to share with you my recent work on the Rho Ophiuchi cloud complex. It's been a hard work due to its low altitude on the south horizon (I live close to Barcelona, 40ºN). Faint details are shown on this broad band image. I only used the best "subs" from a serie of moonless nig...
