Happy April first everyone. This is no fooling, here's your challenge for April!
IC1795, The Fish Head Nebula is a star forming region in the constellation Cassiopeia approximately 6,000 light-years away. It is located near the tip of the Heart Nebula, IC1805
I started obtaining the
Ha data from my
Bortle 8-9 backyard and really loved the composition so I decided to spend some time at one of my
Bortle 3 dark sky sites to obtain the rest of the
RGB data as well as a bit of OIII and SII data for this image.
This data was captured through my Explore Scientific ED152 CF
APO with the ZWO2600mm camera and Chroma
RGB and 3nm
Ha,OIII, & SII filters.
30x60sec Ea.
RGB = 90min
154x600sec
Ha = 25hrs40min
20x600sec OIII = 3hrs20min
20x600sec SII = 3hrs20min
Total Integration Time = 33hrs 50mins
I did not obtain nearly as much OIII and SII data as I wish I had but I still feel as though there is enough to work with here.
Options are a plenty. You can just process the
RGB data as there is a good bit of nebulosity that shows up there.
But considering how rich the
Ha data is, that would be ashame.
HARGB is another way to go or HOO or HOO with
RGB stars or just go for it and give it the SHO treatment and add the
RGB stars to it. This is one of those rare targets that actually has a lot of SII data.
These files are straight from PixInsight's WBPP where they were stacked, aligned, auto cropped. Only Cosmetic Correction and Local Normalization has been done to them during the WBPP process.
I'm looking forward to seeing your version of one of my favorite images.
Here's the link where you can find the .xsif, .fits, .tiff, or .jpg files. You only need to download the format you want to edit as each zip files contains the same data, just a different format.
