My first contribution to Stellarium approved!


My first contribution to the great, open-source astronomy application Stellarium just got approved today! I was playing with its Oculars extension a bit and found out it was lacking support for Barlow lenses, so after some hacking I  proposed it via this branch. You can now find it in   trunk, but unfortunately my change came too late for inclusion in new Stellarium 0.12.0, so the only way to test it is to compile latest trunk code, or wait for  next official release.

My barlow lenses enhancement allows for adding barlow definitions in the Oculars dialog. Just like in the real world, the multiplicity of barlow lens affects focal length of the telescope, and thus increases magnification and decreases field of view. You can of course achieve this by defining additional telescopes with respective focal lengths, but this enhancement makes it easy to play with different telescope - ocular - barlow combinations without much hassle and duplicating telescope definitions. Enjoy.

Telescope case

I've finally made myself a case to carry my MAK127 telescope and another one to carry accessories (eyepieces, finder etc.). It took me around three hours to accommodate each case for its duty - main job was to cut sponge so that telescope and accessories all fit and are protected against shock (BTW, as you can see on the photos, the telescope case is made of a casual toolbox). My next target is a case / bag for EQ3-2 mount, but this seems to be more problematic... Any ideas?
