I dont mind at all doug.. Ps.. Why are you not in the chat room?? Hrmm???

Heres Round 3.. Dougie... Just for you.. I took some flats...

They are not perfect, as the rotation of the camera may have changed slightly (+/- <.5°), but focus distance was exact (digital readout on motorfocus)

I decided I'd just use my PC monitor, Put the refractor on a chair, with the dewshield just off the panel (Didnt want anything touching my 52" monitor....) took 10 flats with 25k ADU, 10 flats with 20k, 10 with 15K and 10 with 10k ADU. The 25K ADU flats worked best.. and heres the result.

Hooray... Flat fielded image!!
