Hi expon,
The photo looks like a smaller dob than 12" I could be wrong but the size of the mount doesnt look right. Some people think that if the diameter f the tube measures 12 inches that it s a 12". My old 6" dob for example measured about 8" but had a 6" mirror. This looks like a 10" to me. If thats the case you can get a brand new one for $50 more at andrews communications. Even if it is a 12", brand new they are $750 at andrews. Just be aware of how BIG a solid tube 12" is. There has been countless discussions on this forum about this topic but it is HUGE!!!!!. Unless you are young and fit and have a large car that is
