Description

As I could borrow an WO FLT 110 F7 APO this is my first picture taken with PHD autoguiding. I have an old Soligor 400mm F6,3 telelens with T2 adapted to an ASI120MM CMOS webcam.

The William Optics has no flattener or reducer which is visible in the corners (flattener that is).

I used a Baader Semi-APO filter to reduce Light Pollution.

This is 25% size reduction in JPG of the original TIF frame. No Cropping done.

No Darks No Flats

Patrcik Jacobs, the owner of the FLT, pointed out to me that the use of the Semi-APO filter severely impacted the color vibrance in the picture. Basically color was almost removed. I will use HUTECH IDAS LPS D1-48 for the next shots.
