The only thing I've got already from that list is the T adapter. I have an el cheapo red dot finder scope - is that an Illuminated reticle???
I feel like I need to go to university to get a degree to understand all the jargon
I'm sure I'll get the hang of it in time...
What is the advantage of having a refractor type telescope over a newtonian or a cassegrain for DSO photography?
