Small bore imaging seems to have a growing following here, I am gratified that so many folks are participating and sharing their results with 6" or less of aperture. With Jupiter on the wane and JasonB's thread encouraging folks with Saturn near opposition, I want to open another small bore venue. Over on the Jupiter small bore thread TrevorN recently broached the idea of a lunar thread with the same parameters; something I have been contemplating for rather a long time...his suggestion got me off my seat and working. Saturn is already a very difficult target for northern hemisphere imagers, and we only have one more good Jupiter apparition before it sinks lower in our skies. The Moon, on the other hand, is always available for everyone and is perhaps the perfect small bore imaging target. While easily accessible and chock full of cool detail, Luna is much trickier to shoot well than folks might think; for instance the terrific dynamic range can make getting first rate images tricky, especially near the terminator. So how about we stick with the same 6" of aperture or less rule, any kind of camera, and share what we have learned about lunar imaging; I'll start off with some examples and open the discussion...
Back in the summer of 2010, 4th of July evening in fact, I was becoming mighty frustrated trying to tweak the collimation on the the still new-to-me C925 XLT I had recently purchased used. It was a great instrument but I needed a break! The air was dead calm that night in the heavy, hazy southern way so I put the SCT up and broke out my SW100ED Pro for some less complicated imaging entertainment. At the time I was still using what I consider to this day to be the worst planetary camera I have ever owned, the Orion Star Shoot Planetary Imager and Auto-Guider or SSPIAAG, a camera with but one virtue in my book: it could take pretty decent images of really bright objects like the Moon. So I broke it out and over the next few hours had something of an epiphany: shooting with small aperture and minimal gear could be both fun and provide very satisfying results. Below are several images I acquired that night, and though I ditched that camera not long afterward, the SSPIAAG really opened my eyes to the world of lunar small bore imaging
Rupes Recta (the Great Wall) and Thebit:
I was surprised at the time by the quantity of very subtle detail captured in these images, and while I have captured many, many more (and better) lunar images since; I remember the shots from this night especially fondly. So what would you like to share as we we get this thread under way?
