Lagoon Nebula

At only 4,320 light-years away, the Lagoon Nebula features an open cluster of young stars age 4 - 6 million years.

Captured with my Seestar S30 at John Glenn Astronomy Park tonight.

Trying to get back to astrophotography after a long hiatus. As a starter, Lagoon Nebula (M8) photons for an hour.

80mm refractor, imx585 camera, no filter, PMC-Eight mount, 30mm guidescope, 2 mins sub, open-source software (NINA, PHD2, ASCOM, Carte du Ciel, DeepSkyStacker, Siril, Cosmic Clarity, GraXpert, Darktable), Bortle 5 sky.

Last night we had a lovely clear sky, so I set up a mosaic with the Dwarf3 around the Triffid and Lagoon nebulae.

I applied my usual post processing steps, and I got almost as good a result as I got up in Beacon with the DwarfII. But only almost, and with twice as long an exposure.

Let's just look at that for a moment, because not all is as it seems.

The D3 has a 38mm aperture, and the D2 25mm. This means that the D3 has twice the light gathering capability of the D2, and has a more sensitive detector. So this image has four times the light gathered as the image in Beacon, but it is also a mosaic covering almost four times the area, so we come back down to the same amount of light per pixel as the D2 got in a true dark sky.

What this means is that if I had taken this shot last week in Beacon, it would have been truely spectacular!

2 hours 8 minutes total exposure, gain 80, Ha/OIII filter.
