Hi,

if portability is not a concern, astro equipment will indeed do the trick a lot cheaper and probably better than a top tier spotter like the Swaro ATX 95 or the Kowa 883.

As has been said, the...

First of all, welcome to Birdforum!

To see details at 10miles you would want at least a spotter, maybe even an astro scope, depending on your portability requirements. Over water the seeing...

Hi,

if you want a scope really sharp at 60x, ED glass or fluorite is pretty much mandatory.

I tend to prefer used alpha glass - Kowa small body scopes (series 6x3 for angled or 6x4 for straight or...

Hi,

ok the position looks ok - my o-ring was too wide and needed cutting out a bit to fit. Then you probably should try a 5mm diameter example - like me.

Hi Mike,

where do you put the O-Ring? It needs to go inside the lug on the eyepiece above the female thread. Just cut it open and shorten as needed to put in there. There's a small grove where it...

yes, civilian Kern bins are not very frequent outside of switzerland and modern examples are quite a rarity (and I'm not sure if they are not just demo units).

Not sure if Holgers review of the...

Hi,

I can't comment on the price as I haven't been into those expensive bins luckily... but the scratch seems minimal and certainly won't affect image quality.

One might indeed check closely if the...

I am a fan of the Mafrotto 500AH for my 1.6kg scope - mainly because it is more stable than the 128RC or 700RC2. Also it allows to vary the position of the scope so it can be properly balanced,...

Hi,

I agree that this effect is normal for a fast refractor without correcting elements but it is certainly not spherical aberration or SA but field curvature or FC. The former would be a flawed...
