Leo Triplet with BORG 107FL & ASI 183MC, Flaming Nebula by BORG 55FL F3.6

I supposed to be at the dark site last weekend. I loaded all of stuff on my car and was ready to go. But I just gave up because of sky condition. Unfortunately no image result during this new moon time.

I didn’t intend to process my backyard test shot. Because of no image result, I got curious what my test shot looked like.

Here is my setup at my backyard.


As expected, BORG 107FL F6 (w/7108) and ASI 183MC was the perfect field of view for Leo Triplet. This is my primary purpose for ASI 183MC (small sensor and small pixel) as a galaxy camera. Following was only a little cropped. Just 7 frames. Obviously lack of frames.


7 x 4 minutes

I agree noisy and low S/N….. One excuse is taken without LPS filter through light polluted sky. I’m curious how a new IDAS LPS filter does for my sky and this camera. Probably that will be the best filter for this camera at my backyard.

John Ottesen in Florida shared with his recent gorgeous image.


BORG 55FL F3.6 + Canon modified T5i (3 exposures ISO 800 )

According to John, he was allowed to take only 3 frames because of sky condition. Very nice. John!
