I experimented last night attaching my ASI071 to an unused 5x2" filter wheel that held a UV-IR cut filter and an 8 nm Ha filter to image with my AT130EDT + 0.8x FF/FR (728 mm fl). I couldn't stay very long at my ROR, so I only ended up with 16x60 sec. RGB frames and 18x120 sec. Ha frames of M42, all unguided. I extracted the red channel from the Ha light frames to create an Ha master and then used NBLRGB to enhance the RGB image with this Ha master. Here is the result cropped for composition and down-sized for CN.
This is how I will image with the AT130EDT in the future.
