M42 quickie with C11 Edge, SX H9, Optec reducer (@f/6.0)

After helping get Jon’s Obsy set up, and finding/fixing plenty of related issues along the way, I think his imaging rig #1 is about ready to go The final piece of the puzzle was fitting the Optec Lepus reducer for the C11 Edge last night, taking it from its native f/10 to somewhere near f/6.2 (actually nearer f/6.0 from the results below!)

So, this is his data from his setup, but he has allowed me to have a play with the data and post the image here. Please note that this is just 20 minutes of data (10 x 2mins), was against a blue sky (8.30pm until 8.50-ish), and was sinking rapidly into the East (PHD was having fits with the guide star movement!)

So long M42, we shall see you again next year… we will be ready!
