With the planet nearing inferior conjunction (which is around a week from now ) all that can be seen is the very slender narrow crescent.
I used an IR900nm filter for the image which greatly helped with contrast.
The scope aperture was also masked down to prevent stray light entering.
I also installed an active cooling system on the scope today which seem to help as there were periods of quite good seeing at times.
