Wanted to get some RGB stars while imaging in narrowband. 20 x 15s subs each RGB. Pretty impressed with what came out of such short integration time! Once I have enough narrowband data I’ll process it and add these stars 🙂

For the integration time this is really good! What coma corrector did you use?

Thank you 🙂 I use the SkyWatcher CC

Which one? There seem to be quite a few models of skywatcher coma correctors. I'm asking this because I'm on the hunt for the best semi-affordable cc for f/4 newtonians for APS-C sensors (not as expensive as for e.g. the TeleVue Paracorr type 2 but something better than let's say the Baader MPCC mark III). I want to be sure that what I will get will correct the field well, so I'm trying to find real world tests.

Specifically that one. I have great coverage on the APS-C sensor and the OAG 🙂 I wonder if the OAG is cause for the odd spike stuff haha

those flares are usually caused by the primary mirror clips causing weird stuff. This can be fixed by a primary mirror mask. They can be bought relatively cheap, even pretty high quality ones. I only really know this one from Backyard Universe for skywatcher newtonians (f/5 and f/4). https://www.backyard-universe.de/en/i/primary-mirror-masks
The mask basically changes the three clips sticking in to a circular "clip" if you know what I mean

Though thank you by the info! Greatly appreciated.
