16 Sharpless objects in one frame with Samyang 135

[gorann]

Here is what my Samyang 135 caught the other night while piggybacking on my dual-RASA rig, aiming at the area around Lower's Nebula in Orion. It reveals quite a lot of faint nebulosity even if the moon was out, so the IDS NBZ filter helped a lot. The annotation reveals that the image actually contains 16 nebulae from the Sharpless catalogue (Sh-2).

Processed in PI and PS, including StarXT, BlurXT and NoiseXT

65 x 5 min, so 5.4 hours. Omegon veTEC571C with IDAS NBZ dual-band filter (Ha+Oiii).

Thanks a lot Michael! Yes, it is a bit like a galaxy chain but with nebulae.

Very impressive, was the framing deliberate or fortuitous?

[gorann]

Thanks a lot Steve! It was totally fortuitous. The Samyang is just hanging in there on top of one of the RASAs and gets what it gets, happy that I at least fix its focus and hoping not to fall off🤣

I have a similar approach. When I put my RASA8 on the Mesu the mount looks a bit under-utilised, so I put the SY135 on there to balance things up a bit, but I don’t need to spend anytime aligning the cameras.😊

I should probably start paying more attention to what he SY135 is aiming at. So far I have mainly looked at it as an extra bonus and only checked out what it captured after I have stacked and processed the RASA data, which got all the planning for the night.
