Love this stuff! I do a lot of IR work with my full spectrum 6D (day and night), but haven't tried it for deep astro. I will have to give it a go!
Love this sort of progressive experimentation!

Thanks Troy! I also have been doing a lot of daytime infrared. I have 590 / 650 / 720 and 850nm filters. I can only use the 650nm and 720nm "through the scope", as I adapt 46mm to 48mm and 48mm just screws in to the focuser.

Thanks Simmo! It says on the plastic container "dHD". I also have a much more expensive Hoya R72 for daylight infrared. I can't really tell the difference between the Hoya and the dHD.
