I'm probably doubling my chances for months of clouds and rain by writing this blog post about new equipment.
New equipment arrived in the mail today.
As I always do with new equipment, I put it on the scope and played with it until I was comfortable that I knew how to use it.
In this case, I was concerned that I wouldn't have enough downward focuser travel for the newly arrived imager. Not enough travel would mean that I wouldn't be able to achieve focus with the new imager without changing the length of the focuser tube, or shortening the length of the scope's truss tubes, or perhaps even moving the primary mirror upwards a smidge.
So, I staged the equipment to see if I had a problem. I opened the front door and pointed the scope at the chimney of a house some distance away.

The verdict? The focuser has plenty of travel for the new imager.
Here is a frame capture of the chimney.

They appear fairly similar.
Look at the size difference of the sensors between the two imagers!
The Pinwheel Galaxy doesn't fit within the field of view of the ZWO ASI224MC.

But, this is a side by side comparison of the business end of the two imagers.

My old ZWO ASI224MC is a wonderful imager! Every image and EAA observation within the last two years was made with it. It's going to continue being my planetary imager.
The new ZWO ASI294MC has a much larger sensor, which means that it'll have a much wider field of view. This, coupled with its greater sensitivity and deeper well, have me really excited.
Here is a screen capture from LiveSky showing the difference in field of view between the two imagers. The point of reference is the Pinwheel Galaxy.

I'm really looking forward to spending some time under the sky with the new imager.
