My first narrowband images with the Rokinon 135mm lens: the North America and Pelican Nebula
The night of October 4, 2022 I used the Rokinon135mm for some deep sky imaging in narrowband for the very first time.
I decided to image the North America Nebula (NGC 7000) and the Pelican Nebula (IC 507) from my driveway.
The Rokinon 135mm lens + ZWO ASI533MC PRO combination is delivering astonishing results with only a few minutes of total integration time.
Can’t wait to image some broadband objects (such as Andromeda Galaxy and the Pleiades) on a moonless night!
