Impressive Cam for the price

Purchased this recently along with my very first actual attempt at digital astrophotography. With no experience and lack of a better word of nasty light polluted sky. The result of M31 was a major surprise for me as a first time trying it. This encourages me to try even more and more now. Good product.

Glad I bought it

Man this camera takes great picture. Never done this astrophotography before but my first target was the Orion Neubla and it amazing.

Long term project

Getting the best out of this camera is going to take some time due to the need to master its many controls and features. But initial impression is very favourable.

Simply Amazed....

I've been shooting with an unmodified DSLR for the last several years and I felt that I was at the point were it was holding me back in my astrophotography. I got great advice from the folks at OPT and I have to say I am thrilled! I don’t know why I waited so long to move to a dedicated astro camera. Of course the weather has been horrible for a month after delivery. I had my first opportunity to try it this past weekend. Using NINA capture software..everything connected flawlessly, the included manual was “Spot-on” re: spacers needed to get correct backfocus, and setup. When my first sub downloaded of the Pelican Nebula, I was thrilled to see “red” Ha data for the first time imaging.. very low noise. Honestly, I think I was most excited not to be taking dark frames at 2am... Thanks OPT for the great advice.

Strange artifacts

I wanted to love this camera—it’s fast, sensitive and creates great images. But with a light pollution filter like the Hutech IDAS-LPS P2 or D2, or the Triad Ultra Quad band filter, it creates weird red and green streaks and blotches in the background that are hard to get rid of—or cause you to lose nebulosity when you do. It took me a long time to figure out it was the filters, and maybe it isn’t—there are lots of posts on the internet about similar problems. Check around and see what other people are saying, but if you’re in a light polluted area where you’ll be needing a filter, you might want to look elsewhere. I returned mine and am awaiting an ASI2600.

A new frontier

This is my first cooled camera. Wow!!!! Because of stormy weather I have only been able to use it once. But what a night it was. My target was the Sunflower Galaxy. Cooled to -10 and away we went. Super sensitive and no noise. I shot a darks library to get the ball rolling.
