I use registax to stack and for wavelets.
The seeing conditions in Melbourne is rarely better than about 2-3". In fact lately the typical seeing conditions is clouds.

Hi Tony
I found that using a motorised focuser significantly improved the image quality of my medium to high resolution lunar images.
Just being able to make micro adjustments to the focus, whilst looking on a computer screen without physically touching the OTA/Focuser, really changed things for me.
Either by using a Bahtinov Mask on a nearby bright star or just eyeballing the smaller craters on the moon’s surface until they snap into sharp focus.
I started off with a JMI Moto Focus with a hand controller, then purchased their USB Focuser so I can now focus from the Notebook screen.
Cheers
Dennis
