Remembering Earth-that-was
This is not the Rosette Nebula, as I first stated. Instead, it is the Lagoon and Triffid Nebulae — got my wires crossed. This image is a 300 second single exposure. The color is somewhat arbitrary…
I also took several 1 second shots trying to frame things; for grins I stacked them and you can see the result below. It’s interesting because to me it looks more like a painting than a photograph. But 1 second exposures…
NGC 7635 is actually a rather small object, less than a quarter degree across. My imaging setup has a field of view of 4×2.72 degrees, and the object is a little above the center. The open cluster in the upper right quadrant is M52.
Below is a closer crop of the above image, showing the perfectly circular “bubble” in the center.
As counterpoint, here’s an exquisite image from the Hubble.
This image is a stack of about 30 10 minute exposures, taken over two nights.
This is the same data (27 exposures, 3 minutes each) as in the previous post. Four different ways of combining the exposures, and two different methods of removing background coloration (an overwhelming green from the light pollution filter I was using) from the resulting image.
I think the second one (“integration-ABE1-“) is best, but I was a bit slapdash in preparing the images for posting, so that may be an issue…
This is the North American Nebula, with a bit of the Pelican Nebula at the bottom. A stack of 27 3-minute exposures. I’m not sure why there isn’t more color; color still remains a bit of a mystery to me…
Remains of an exploded star. This is over an hour exposure total, through a 61mm telescope, in not so great suburban skies.
