Re: Wemacro Micromate questions
Thanks very much for both replies, and good to hear that I am not entirely at fault for the inability to align and the various stability issues I believe the device has as shipped. I don't believe either of you is in the US, so I hope I can find someone who can help me improve the stability... I sho...

Wemacro Micromate questions
I just got a WeMacro Micromate and am having trouble aligning it to the focuser on my (Motic BA310POL) scope, and I think there are some basic design issues that are at least partially responsible. I'd like to PM with someone who owns one and/or someone who might be able to help build a new mount fo...

Re: My first crystallisation Caffeine
I think my favorite results currently are from urea, thiourea, beta-alanine and most of those mixed with glycine. That could keep you busy for a long time ;-). Some people melt their compounds on a slide on a hot plate, which I have tried, and others use a tea candle or a Bunsen burner to speed up c...

Re: First Light
Thanks, Mark. Lots to learn here. The goal is to get it as thin as possible to avoid stacking, but I'm used to stacking from my DSLR/tube lens/scope objective work, so I will definitely give that a try.

First Light
First light with new Motic microscope. Melted menthol at 40x (10x objective, 4x photo adapter). Single shot. Looks like it needs sharpening and possibly a stack would help. Suggestions welcome.
