Hi Rich
Spikes.....sorry mate,I tried hard to resist but resistance was futile!
Ah,like I mentioned in the first light post,I had to use an extension tube to get to focus and It was one of those cheap one thumb screw bintel ones...cause It was going to create issues,I new that but didn't think I had anything else with me on the first night.
The next night I ended up finding some screw on T-thread extensions that I could use,so hence the improvement.
