Description

It took 5 nights to capture this 2 panel mosaic from the Rosetta nebula and the Cone nebula.
Often overlooked is the Supernovaremnant SNR G206.9 +2.6 in lower the east side.

Each frame was 2h for Ha and 3.5h for OIII (so 11h for narrowband)
For the RGB stars I used a Sony A7R4 (Kolari modified) with an STC-Astro Multispectra filter and exposed 2 hours

To fit the ASI 294mm at the 135mm Samyang I used a selb build adapter (see info here:
