Description

Finally seem to be getting into production with the Takahashi. These were collected and processed between 9PM and 11PM April 20.

I have discovered that the collimation will change over the night probably due to the heavy (5.2 lb) SBIG camera sitting on the focuser and rotator of the scope. But knowing this, it is not too bad and at least I will not chase my tail.

Scope remains focused over several days.

Processing follows:

Except no deconvolution. I will try a variant later but not fully happy deconvoluting the L alone. The image integration is done with the PI AIP script.

Thanks to everyone for all the comments to help getting this puppy to hunt.
