Re-aluminising at Orion Optics
I've just had my 14in Newtonian mirror, and 3in minor axis matching flat re-aluminised at Orion Optics, this is the second time I've been there for re-aluminising, the last time being in 2013, previously I went to David Hinds, when they used to do aluminising, and at one time had the lion's share of aluminising in the UK.
I can speak quite highly of their Hilux Coatings, and find them quite durable, the previous coatings were still in quite good condition after 12 years, and only decided to have them re-done to improve the visibility of the fainter satellites of Saturn while the rings are edge on (and based on my view of Saturn last night it has made a difference), and maybe also my first glimpse of Neptune's Triton (although I have managed to photograph it on one occasion).
With living only about 50 miles away from Orion Optics in Newcastle under Lyme, I decided to take and collect the mirrors in person, rather than risk them getting damaged or last in transit. When I spoke to John Pemberton over the phone, he was quite helpful (previously I dealt with his father Barry), in addition to the re-aluminising, I also asked him to put a central marker on the main mirror (to aid collimation), and to remove and re-glue the secondary on its holder, for which there was an extra charge.
My only criticism was the timescale, originally I was quoted 2 weeks, but it was nearly 5 weeks before the mirrors were ready for collection, otherwise I would have given them 5 Stars. Maybe the extra work of marking the main mirror, and removing the secondary from its holder and re-gluing it place, resulted in it taking a bit longer.
