Sh2-155, the Cave nebula

[jfd]

Hi all.

 

Last october I took a total of 130 unguided images (L,Halpha,R,G and B filters), 15 minutes each, of this object with a VISAC at 1800 mm focal length over a DDM85 mount.

 

I employed the latest beta versions of Autoslew and Sequence, always using MLPT.  127 out of 130 images were perfectly tracked, only 3 images were suboptimal. All images were well focused by Sequence (focus time interval: 60 minutes)

 

Link to the image (you can find there a 100% size image also):
