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,
To celebrate the 25th anniversary of Sir Patrick's DSO catalogue, I've added the available Caldwells to my basic Marathon search sequence.
Those interested may be pleasantly surprised by how many of the additional treasures are only a short hop from a given (or en route to the next) Messier.
The sequence for 40°N can be found at the SEDS Messier Marathon homepage or at my blog.
The August edition of the Binocular Sky Newsletter is ready. As well as the usual overview of DSOs, variable and double stars, this month we have:
* A grazing occultation of a bright star
* Moon occulting stars in the Hyades
* See both ice giants as well as Vesta
* Review of the Celestron EclipSmart 10x25 solar binocular
I hope it helps you to get the best out of these late summer nights with your binoculars or small telescopes.
To pick up your free copy, just head over to http://binocularsky.com and click on the Newsletter tab. You can also subscribe (also free) and have it emailed each month.
Warning: Do not attempt to observe the Sun with any optical system that is not specifically designed for the purpose.
I've decided to stay in the house tonight with the anticipation of some clear skies later on, and to hopefully get the chance of splitting a few double stars - something that I've never done before. After a while looking through some charts at my desk with a rather nice glass of red, I've come to the conclusion that Cygnus and the Northern Cross seem like a pretty good place to start.
My first port of call will definitely be Albireo at the foot of the Cross.. I'm excited about this one as it sounds like a beautiful view through a pair of binoculars, not to mention the easiest to find! I'll then move over to the Cygnus triple all being well and then the three doubles (Mu Cygni, 79 Cygni and 61 Cygni).
Now all that's left to do is await the darkness, and hope the clouds disappear!
Hope you're all having a great weekend.
Cheers, Mark 😁

On the 2nd of July I closed my curtains one night before I went to bed but, before they were shut I noticed a strange multicoloured light flickering low in the sky in the northern celestial hemisphere. I Thought to myself if that is a star it looks amazing. The next night (3rd of July) I decided to take another look at this multicoloured light which was still there, Only this time I used my binoculars, I was seeing blues, greens & reds. We have all seen stars by looking up into the sky but, I have never seen a star create multi colours before. It makes you feel excited inside and you think that no one else can see this until you tell them and share the same experience together. I believe I was looking at the Capella Star which is the brightest star in the constellation Auriga and your not kidding it is bright. I cant wait to have another look tonight to see if the multi colours are still there. I would like to have taken at picture of it but I am not setup to do that just yet as I am very new to star gazing. I wish someone here can confirm what I saw and to post a picture of it would be awesome.
