Eagle LAGB from mixing narrowband data

[Slawomir (Suavi)]

The effect of my attempt to refine about 3.5 hours of data (12nm H, O and S filters) with PI. (HEQ5 and 100mm doublet)

A lot of fine detail there. Looks really good.

It makes the point very well that with narrowband imaging, a doublet can do the job pretty darned well.
Nice work.

Good things about a doublet are that it is definitely cheaper and possibly lighter than a same-sized triplet, but using an OAG with a doublet is a real pain - adjusting focus after changing a filter de-focuses guide camera a fair bit. That is why I went back to using a guide scope, which in turns brings problems with a flex...

Thank you for your kind feedback :-)

Great detail.

A very nice looking photo.
