Dinoboy Posted May 17, 2020 Share Posted May 17, 2020 Hello everyone, due to having a street light about 24’ away from where I set up ( there is nowhere else in the garden) I have to use various filters. I have just purchased a Williams Optics Space Cat and was wondering if I add a filter draw do I need anything else to enable me to achieve focus.Thanks for any advice.
