trying vertical offsetting

Submitted another series of experimental image requests for the BGO.

This time I was interested in seeing if the vertical offsetting would work they way I wanted.

The offsetdec option was used. I'm looking for a positive value making the telescope shift position to the north...

I also requested the hydrogen-α and ionised oxygen filters be used. I'm assuming there will be lots of interesting stuff going on in the Rosette Nebula with hydrogen atoms...

And finally, I wanted to see if the image quality with the SBIG camera improved with a new flats run...
