Lagoon with LX-90 and Lepus 0.63x focal reducer

Hi all,

I've dusted off the LX-90 with the arrival of my new Lepus 0.63x focal reducer. I trialed the setup on M8 (Lagoon) as follows:

Mount: Standard fork for LX-90, unguided.
Camera: Canon EOS 1100D (unmodified).
Imaging done with BackyardEOS v3.

Imaging consisted of bias and lights only at ISO1600 with 2s/5s subs. Total time is 11 minutes. FOV is 36.3 x 28 arcmin after my severe cropping. Up is -67.6 degrees E of N.

I admit to not spending much time on the processing (DSS/CS2), there is fainter nebulosity there, but I couldn't bring it out without burning out the core.

One issue was the limit in elevation; at most I can image up to 62 degrees- the camera, adapter and focal reducer stick out quite a ways. There is a slight curvature when you look at the flats, easily correctable with Gradient Xterminator (or flats) and I'm happy with the wider FOV! All I need now is to get a wedge and guiding system for longer subs!
