While you are at it...

Instead of getting a new 1/4" thread adapter in the scope foot, I'd start to use the more reliable 3/8" mount on the head / QR plate.

LOL - I could try to do it when I get home tonight. It is a very simple, thin metal ring with bayonet fingers and a locking screw. It brings the eyepieces a couple of mm's up, which means that some...

Roland,

I haven't used the lenspens with any hydrophobically coated lenses, but I don't think the cleaning fiber/rubber or the "graphite replenisher" themselves can cause any damage. However, I know...

I have had a chance to compare the 25-50x and the newest "non-S" 20-60x eyepieces (Swarotop & Swarodur but not Swaroclean coatings) on both the AT80HD and ATM80HD scopes. Mechanically the mounts are...

A DSLR lens is not afocal if it has focal length ;), but if you put a short-fl -lens behind it, it becomes an afocal "magnifier/multiplier". The problem with an afocal system is that it does not...

Dale,

I agree mostly with Steven here. A spotting scope is afocal ie. it does not have a focal length at all - only magnification. This magnification is like a teleconverter that just multiplies the...

Josef,
One important point re your original question is camera-eyepiece -compatibility, which can vary a lot. With your earlier zoom setup you had an eyepiece (old Kowa 20-60x?), which practically...

I think we are approaching the point when high-sensitivity sensors and electronic displays actually become viable alternatives to optical eyepieces.

Nick,

If you plan to use the scope mainly for viewing and digiscoping would be a secondary purpose, I would be tempted to recommend the zoom instead of fixed eyepieces. Both Kowa and Swaro zooms are...

Yes, my original plan was just to test whether or not the new eyepiece works on my trusty, and not too old, AT80HD. I was very happy to see that it did - and I would say that it did just as...

Sancho,

If your SVs eventually end up being left unused and unloved, please consider me as a potential and experienced adoptive parent.

Kevin,

It is because phase detection AF of the DSLRs require apertures of at least f/5.6, which can't be reached with exit pupils of 2-4mm. It does not help to have a fast lens behind the scope if...

That is how they have been able to make the new zoom better. The new eyepiece mount is larger which...
