Dang what focal length is that?

#

Man i can't even get such details at 1200mm :(
Idk if its cuz I'm shooting on a telephoto lens or if it's cuz I'm not doing narrowband

#

How does aperture affect the results?

#

Also is this stacked or single frame? If so how many stacked frames 👀

These are goddamn amazing

#

Perhaps my dslr sensor resolution is too low

#

Dammit haha

#

Eh when (if) I start doing mono/narrowband I'll give it a second shot ig

Because of physical resolution. The granules on the sun barely reach 1 arc second. For this type of detail, a 6" or higher aperture is required

So there's no way around it other than increasing aperture size?
