Browsing Fits images of galaxies
Posted: Sat Feb 03, 2024 11:22 am
Hello Robin!I was able to discover supernova SN2024ahv in galaxy NGC6106 on January 16 using SharpCapV4.1. This was thanks to SharpCapV4.1. Thank you so much.
I live in an urban area where even on a clear day I can see 4th magnitude stars at best, but thanks to Live Stack I can capture objects at 17th magnitude by galaxies at 13th magnitude.
I use ASI294MM on C9.25 to introduce galaxies with 4 seconds of live stacking and compare them to the DSS image. 8-10 stacks and if there is nothing unusual I go to the next galaxy, no Save. At this time, I use both automatic and manual histogram stretching, and this operation gives me a very exquisite view of the stars overlapping the arms of the galaxy.
Now, I have been having trouble with this histogram stretch because it is too good to be true.
Recently I have been experimenting with another method of searching supernova in Galaxy with a list of coordinates while using a sequence editor to automatical. In this case, I use the Fits brwoser to compare the captured image with the DSS image after shooting, but at this time I do not have a Fits browser that can do the same exquisite histogram stretching as when SharpCap is live-stacked. I am currently using Zwo's browser.It's a good software, but I wish it had more granular controls.
1 Robin, do you have any recommendations for a Fits browser?
2 Would it be possible for you to create a great Fits browser?
