Hi everyone,

a break in the weather on Thursday night, (25.02.21),
allowed me to once again to take an opportunity to put some
theory into practical application.

I chose Orion, as it was the obvious target to experiment with.

This was the first time I had used my Skywatcher HEQ5 Pro mount.

I had Polar aligned, and set the mount up with EQ Mod and Stellaruim.

Note of mention, Polar alignment was achieved with the QHY Pole Master.

A huge shout of thanks to Eden, (Brett) for the Pole Master.

A big thank you to Startrek ( Martin ), for the procedures.

I was pleasantly surprised with the tracking, and am looking forward to
trying guiding when the next clear sky eventuates.

Details of the image as follows:

102mm x 500mm Skywatcher achromatic.
Canon 600D DSLR non modded.
Skywatcher HEQ5 Pro.
Field flattener.

110 x 20 second subs ISO 400 taken in APT.
Best 100 stacked in Deep Sky Stacker.

Processed in Windows 7 Live Photo Gallery.

No cropping.

Imaged under a full Moon.

No filter.

I am hoping that some advise can be given in regards to the
checkered artifacts in the bottom of the image.

Would darks help remove these ?

I have tried my hand at Startools, (trial version), but have not yet mastered the mask technique.

Would masking during processing also help remove the checked area ?

Once again,

thanks for looking.

Comments always welcomed.


Paul.
