I’m working through some equipment tests before I use my ZWO ASI174MM for Deep Sky Imaging. Using RGB and a UHC filter, this camera can do well. The video above shows some of the simple setup challenges I needed to investigate before I setup and attempt to use the ZWO ASI174MM for deep sky imaging. The most notable issue I ran into was where to place the UCH – or – light pollution filter. Depending on where it’s placed in the imaging train, it will collide with other filters, or scrape against the filter wheel when you’re rotating it between RGB filters.
If the weather holds, I’ll be out tonight giving this a try. I don’t expect an APOD out of this exercise. Tonight (or some other night this week) is really all about finding out if the combination of RGB filters and my Meade UHC filter are able to produce any usable sub exposures from the ZWO ASI174MM for deep sky imaging.
This is a part 1 post because I intend to continue using the ZWO ASI174MM for deep sky imaging, and I hope to learn and share my new knowledge with you. So far, my biggest hurdle with deep sky imaging has always been the light pollution in Dallas. Using my light pollution filter for visual use has been boring, because everything looks so green. Hopefully I can image with the filter in place, and be able to eliminate a large amount of the sky glow. The ZWO ASI174MM has the ability to bin the pixels, which will help boost my signal to noise ratio, bringing out details that are otherwise muted because of the two filters in front of the imaging sensor.
My Facebook page and Twitter account will have raw images uploaded as soon as I capture them. As I said before, I’ll post a followup blog to using the ZWO ASI174MM for deep sky imaging after I take the images, and I should also have the stages of my post processing workflow outlined so you can all follow along with how I may have corrected any color flaws due to the UHC filter.
Thanks for reading!
