imaging with go-to dobsonians

[spears5444]

Has anyone tried imaging through one of Orion's large  go-to dobsonians such as the 14"?  I was wondering how well these scopes track, and what kind of exposer times have been used.

Basic planetary can be done I believe, but DSOs are a no go - but I am no imager

Very short images 15 seconds, high ISO if using a DSLR might give enough subs to stack, really a case of try it and see, will also require a Coma Corrector but i would see if the stacked subs works first.....

Short indeed

Here are a few

Be aware that 1200mm+ focal length is not ideal to begin with, and you may not get into focus with the DSLR (backfocus, perhaps with a flextube or modify the mirror cell).
