Hi, I want to share a summer classic, the core of the Lagoon Nebula. My goal was to capture the core of the nebula with all the fine details without over exposing it. After a couple of tests it was clear that I cannot go longer than 5min, otherwise the core will be clipped.
The image was created using Ha as Luminance.
Ha was captured with my TOA150 and Atik 460x, The color data was 'borrowed' from one of my old captures (circa 2014) with the same camera but with a 12inch Newtonian.
The TOA is way sharper than my 12 inch Newtonian and the star profiles are fantastic.
The attached image is a crop at native resolution. (moderators resized the photo to comply with TOS, if you want to see it full res please click to the external link)
OTA: Takahashi TOA150
Mount: Paramount MX+
Filters: Astrodon 5nm
Camera Atik 460ex
35x5min Ha, used as Lum (TOA 150)
