On a night of not so good seeing The Voorwerp was not that difficult with the Sloan G filter, if we did not have the filter I do not think we would have seen the Voorwerp. With Jerry's excellence tracking with his scope all we had to do was be Patience and wait on the seeing. I think it will be direct vision on a good night with the filter. I also think it could be seen in a smaller scope under good conditions with the Sloan G filter and high power.
This is my sketch I did some years back with my 48" and no filter.
