[snip...] I actually prefer using the Kellner!

Same here. With my 127 I spent part of one evening doing a shootout between the cheap 25mm plossl that came with my 90 and the cheaper 25mm Kellner that came with the 127. Both were satsifactory, but ever so slightly, the edge went to the Kellner.

Need to post that in the EP forum lol ;)

 

 

I wouldn't dare ! :lol:

 

Regards

 

Andy.

Balancing the surrounding costs for the C90. 

 

Weight and mount cost:

- Duck tape, piece of wood and a hammer on the ES Twilight II mount. :grin:

 

Cost balanced and most used EP:

- AT 20mm in binoviewer.

(please disregard the counterweight with green text on the back of the scope...)

 

Winged Eyecups:

- Bicycle tube, cut to snug fit on my face.

They block 100% light from the sides. (The street light at my house is like a close encounter with a white dwarf.)

Works really fine, they also help keeping my eyes centered in the EP, so no blackouts or continuous searching to find the sweet spot. Allows a much more relaxed viewing. Never leave home without one, my best update so far along with the binos.

Excellent idea!
