Jones-Emberson1 planetary nebula

[Yoddha]

Hello,

Allow me to share a test image taken as first light of new filters. Total light is 5h (15x1200s Ha & OIII), TOA130, QHY22, APT, PHD, PI, PS

 

 

The planetary nebula Jones-Emberson1 (JnEr1, PK164+31.1) is 1600 light years (ly) way, around 4ly diameter. Its visible size is around 6'x7' spreading 14m which makes the surface brightness very low. The blue dwarf in the center that is driving the whole show is just 16.8m. And this is a spectacular show! Earth size dwarf is emitting enough UV power to blow and lit ~4ly big bubble!

Just wondering if you have an issue with tilt here - the stars in the top left don't look quite as sharp as those in the bottom right?

Hi Graeme,

There is an issue with the scope which I'm still trying to figure out, but in the end maybe will send it for collimation...
