A quick note before we begin: Any scope listed in the poll is an example of that size. Other optics of the same class still qualify.
There is another poll asking what people have as their largest scope; what I would like to know is what sizes people are using, or intend to use, for imaging. I searched the archives and couldn't find a related poll, so I do hope that a few people are willing to provide their comments.
Please tick all that are relevant. If your size isn't listed, please round up/down to the nearest option or up if they are even. If you have a scope which is not your primary imaging scope, feel free to exclude it form your answer. For example, if you've hooked a camera up to it once just to see if it could handle it, but don't think you would seriously consider using it for imaging, feel free to not include it.
I'd also be curious for those willing to provide it to know the model of scope/lens being used. I'm after all types of imaging here - anything that you point at the stars and have a camera on the back end of, camera obscuras omitted :P
The other aperture poll shows there are a lot of 8, 10, and 12" dobs out there, but one thing I would like to know is how many people are, for example, imaging through an 80mm and saving their light bucket for visual use. I'd love to work f/ratio in here, but it would be ungainly to implement through a combined poll.
If you have camera lenses that you use or intend to use at least semi regularly, please include them as well. For example, a 200mm f/2.8 is ~72mm aperture.
The options include a sampling of scopes in that aperture range for ease of conversion by those who may not be so conversant in SI measure.
I've set the poll to four weeks so that it is a snapshot of current equipment and not a running tally, and also because polls float back to the top every time someone submits an entry.

Eric
