I've also found that when I've stripped down DOI teleconverters for other makes of camera that the lens assembly has been slightly different too. This means that different ones wont be a straight fit into a 1.25" tube. A lot of 1.25" tubes are different internally so it's not always so simple. I think where possible it's best to work in the 2" format which is how I currently have mine mounted. I got a piece of black plastic tube from B&Q which is a nice push fit into my T-ring/2" scope adapter which in your case is the Max DSLR. Then I got another smaller diameter piece of tube which is a nice fit into the black plastic tube. Then I fit the DOI assembly into that. Sometimes it involves winding lengths of electrical tape around certain bits to pack them out to make them a nice fit but it all works well in the end which is all I'm after. A lot of this digiscoping stuff involves hunting round for bits and pieces but it's worth it to save loads of money. Ideally I'd just like teleconverters in EOS mounts but I don't think Santa will be that generous this year. |:d|Paul.</blockquote>
