New image from my Sigma 135mm/asi 2600 mc Air setup.
I tested a 3-panel mosaic around the Iris Nebula in the constellation Cepheus.
It is surrounded by many other famous targets that I’ve already had the opportunity to capture in different fields, such as the Dark Shark Nebula, LBN468, LBN528, etc.
I took this image in 6 nights:
2 nights traveling without filters for dust and stars, and 4 nights at home for the Ha with the full moon and the light pollution.
About 4 hours without filters per panel and 7 hours with the L-Para filter per panel for the Ha, or about 33 hours for the whole thing at F2, which helps.
