Is there any way to check that an optical coating is OK?

so when you adjust the focus knob you're moving the eyepiece focal point closer to the telescope focal point, where they meet is the point where the image is clear. Do I have this right?

Could someone tell me what is happening when I turn my focusing knob and an image becomes clear (in focus)

ok thanks. I just wondered if the tri pods are the same and if so is anything else so I can re-use what I can and reduce cost

How much of my EQ5 can I reuse to upgrade to HEQ5

thanks, that;s helpful. is the extension used to increase the focal length? I've been told I need a barlow lense and a T Ring to attach a camera

good advice, thanks. I'm going to leave the mirror and just crack on and learn based on what I have.

sounds like my best option is to get to know what I have with a view of progressing to HEQ5 at a later stage, thanks everyone. could someone help me identify these items. I know one is a filter but what for (I think its a moon filter?) also while I get use to what I have, what is the max. exposure if I don't have tracking.

thanks for the replies, the mirror appears quite clean now it's warmed up and dried out so will leave this for now. I'm looking at http://www.opticalvision.co.uk/astronomical_accessories-motor_drives_and_goto_upgrades/enhanced-dual-axis-motor-drive-for-eq5-mount.html to help with long exposure AP but I need to check other items I may need to attach the DSLR and get it in focus. At 68, this is real excitement!

could you post an image of what an EQ5 looks like with motor drives fitted?

I've recently inherited a sky watcher reflector (see attached) and various buts & pieces including the mount and I have a few questions ... 1. Can someone tell if me if this is an astrophotography reflector? 2. It's been in the loft for a few years and I'm leaving it for a few days somewhere dry and warm but I may need to clean the mirror. any advice welcome? I'm no expert but not clueless either.
