Interesting area. Looks like you've got a satellite in their though.

Always interested to see a Hyperstar image.

Comparing to my C9.25, it looks like your star shapes are better than mine.  Do you make any special arrangements for the camera cables?

I’m surprised that the emission nebulae in your image appear quite faint, but I guess it’s all in the processing. Your exposure is 55 minutes, mine is 52...

Yes, I removed the satellite trail and afterwards realised I removed it from the wrong image 🤪.  I will post it soon.

I have a feeling that the faintness of the emission nebula is due to neighbours garden lights which I am currently trying to address....wish me luck!

 

What camera did you use for yours?

The camera cables are basically held in place by the Dew Straps at the front ( 90 deg apart ) and passed through the C11 handle at the back before joining the rest of the cables to the powered usb hub on the floor.

Ah, well, yes, that may do it.  Good luck on that!

This was a QHY8L, 26 x2 minutes exposures. 

My camera cables are held down by a heated dew shield, but curve rather randomly across the corrector plate before arriving at the edges.  Must do better!
