Swarovski SLC 8x56 or Canon 10x42L IS for Astronomy? (1 Viewer)

[Elpha8888]

I had all of these binoculars, and Canon 10x42 IS is far sharper than Swarovski.
When Image Stabilisation is ON, Canon EAT Swaro even more.

Here is one of my numrous reviews and comparations I did

I've actually spent a lot of time under the stars comparing all the Canons and mainly EL and NL Swarovskis, I've yet to test the 15x SLC.
The 12x Pure being my favourite astronomy binocular this far and like others have mentioned the 15x Canon is the one to go for. An honourable mention to the little eii in which has given me hours of pleasurable night time views as well.
I do not think it is fair to compare the Canon 10x42 to the Pures, the Swarovski are in a different league altogether.
Kind regards
Bobby

Alex, I will take the SLC 8X56 for $500.

The Canon 15x45 IS is renowned for fine optics.
It is, I think, a roof prism binocular.

I looked at the bright planet Venus with the 8x32 BA and 12x50 Ultravid and there is no sign of spiking from roof prisms.

Looking directly at a street light at 7 metres I could just detect some flaring probably from the roof prisms, but this is extreme.

With an Inara 9x36 spiking from roof prisms is intense and rolling ball is upsetting. Edge performance is poor.

I think it likely that top quality roof prism binoculars have minimal spiking but cheaper roof prism binoculars may well have poor accuracy with their roof prisms, which results in spiking.

In general a cheap Porroprism binocular is likely to have better optics than a cheap roof prism binocular.

Regards,
B.

Yes, it was already clear to me it was about the observation with the Canon!
So it's bad for you with eyeglasses too?!

The problem with the IS glasses is that practically all of them are not completely suitable for spectacle wearers, which should also deter quite a few people.

Interesting, as my glasses correction is 6.5 diopters and I've no trouble with the Canon 10x42.
It has been noted that the limited eye relief of the Canons is less of an issue for users with myopia such as myself.
It appears to be true, but I don't really know why that should be the case. Can anyone shed light on this?

Convex lenses are used for long-sightedness, the optical center of which is at the thickest point. Concave lenses are used for short-sightedness, here the optical center is at the thinnest point.

Thank you, that helps me understand.

A diverging lens used to correct myopia is going to place the exit pupil further away from the eye lens of the ocular.
The opposite is the case with converging lenses used to correct far-sightedness, so the far sighted are more demanding as regards eye relief requirements.
