As part of my equipment reduction, I'm selling the following items:
Vixen HR 3.4mm (like new) £200 Vixen HR 2.4mm (like new) £200 1.25" Lunt Herschel Wedge (prism, ND filter, and wedge housing structure like new. Locking screw requires tapping and threading. Hence the discount) £80 SOLD The Vixen HR are the best eyepieces I have ever owned. A few members on CN matched them with the Pentax XO. No light scattering and incredibly sharp. In my opinion colour tone is neutral and sits in between the Docter UWA and my Zeiss Zoom eyepieces. Eye relief is comfortable if spectacles are not used (which should not at high magnification).
The Lunt Herschel Wedge is an excellent tool for white light solar observing using a refractor. It works even better when combined with a Baader solar continuum filter in my opinion. The hole of the locking screw of the solar wedge requires tapping/threading. Apart from that, everything is in excellent conditions, essentially indistinguishable from new items.
Caps and boxes (hard case for the wedge) are included, of course.
Price includes 1st class RM signed-for. Payment via PayPal (as friends) or bank transfer. Collection from Cambridge also available if preferred.
Thanks for looking,
Just wondering what peoples thoughts are on the pro's and con's of the different types of mounts out there? Do Dobsonian mounts have issues on non-flat surfaces (like a garden) or can Equatorial mounts ever have issues getting out of line too easily?
I am very new to everything to do with astronomy/looking through a telescope and I have recently bought my first scope (a 8" dob) which came with a 25mm and a 10mm eyepiece but I am looking to upgrade but don't know what is good.
Any help or advice on what eyepieces I should be looking at buying would be much appreciated (budget is anywhere form 0 to 100 pounds per eyepiece)
Very happy with it! Wish the sky were clear, but as we all know, when we buy astro equipment, it's cloudy! Argh!
The telescope was collected from David Lukehurst at noon and then we travelled back to Cambridge.
