Description

Last image I took with the 2x Barlow, I believe I didn't get any more details compared to a setup without the Barlow despite the higher resolution and having as the only measurable effect the inability of subtracting the flats properly (tons of "donuts" compared to my normal flats without Barlow) forcing me to raise the black point a lot and losing details in the process.

I also spent a lot of time in post processing but the results are average and I didn't even manage to combine the Ha subs without unbalancing the image too much.

Given M51 is like a pizza (you can't ruin it too much anyway!) the end result is pleasant enough to the eye, enjoy!
