I posted a question about the Orion Starshoot G21 the other day, and since nobody responded to it, I figured even considering that camera was probably a bad idea. Now I am currently in a dilemma where I am unsure if I want to go with an OSC camera, or take the plunge and go Mono. I currently am shooting a T3i when it is cold, and a Rebel XS when it is warm. If my T3i sensor goes over 17C, my images are worthless due to all the noise. It is one of the main reasons that I want to upgrade to a cooled camera, it would allow me to shoot more often. I am using an Orion ED80, and I have a AT73ED II on the way for more widefield shots. I want to make sure the camera that I get will fit those scopes nicely and maybe have a little wiggle room for upgrading the scope next year (Probably in the 800mm range, I am looking at the Orion EON 115mm Triplet). I only shoot DSO's, and mostly nebula from a Bortle 7 location. I did just get access to a dark site/observatory that I will be making use of this year. That being said, I have been looking through these forums for the last few days and my decision is even harder now. I have essentially narrowed it down to the ASI294MC Pro and the ASI1600MM Pro. With my budget, I could get the ASI294MC Pro, and a nice LP filter then slowly start getting some future proof 2" Narrowband filters to be ready for a Mono camera down the road. If I get the ASI1600MM Pro, I would essentially get the cheapest 1.25" LRGB Kit and then slowly start to get Narrowband Filters down the road, but then I have my DSLR's to take OSC images still. I have been looking around Astrobin and forums, and I really like the end results from the ASI1600mm Pro. It seems a little daunting with the amount of work that goes into getting those images, considering how many clear nights we have here. Looking at the ASI294MC Pro on Astrobin, the images are not all that big of an "upgrade" from what I am essentially getting with the T3i and Rebel XS. I know all of this is personal preference, but I was hoping to get some others input that were in the same situation that I am in. Is it really worth the extra work/money to go Mono? Also, has anyone had good results doing Narrowband with the ASI294MC Pro?
