Fearsome! (-: 

I tried it with M27 and it looks great. I suppose there is no way to remove 
image from map without using FITS manager.

I've found two bugs so far. 

1. Fits manager doesn't appear in menu if kstars is compiled with indi
support. You need to add following string fitsmanager to kstarui-indi.rc
                  <Action name="fitsmanager" />

2. I tried to open FITS file and got segfault. It's two dimensional and do not 
have any information about object. I can send you file if you need it.

It's likely. I looked into fitsviewer and its code is very far from perfection.
Static analisys tools complain about possible memory leaks and so forth. 
I have few patches with half-hearted attempts to refactor it. I'll check and 
commit them

Sorry for delay
