Solar filter

I ordered a Solar Filter today from TelescopePlanet.co.uk, after calling them to make sure I could get the right solar filter for my Celestron C6-N.  They told me it’ll go in the post today, but given that it’s a bank holiday weekend, there’s no telling when it will arrive!

Very pleasant on the phone though, so I’ll shop with them again!  Once it arrives safely, I’ll add them to my list of recommended suppliers.

No sign of the 3.3x Barlow and I think the postal workers are on strike tomorrow, so looks like it’ll be Tuesday at the earliest now.

I was thinking last night that it would be good to be able to view the sun through the telescope. It’ll give me more “telescope time” while it’s staying light so far into the evening.

So, I started researching solar filters and found a major price difference:

I think the difference is in the material – the cheaper one is glass and can shatter / break when dropped.  The more expensive filter is made of Baader Astro Solar™ Safety Film, which is apparently far superior to glass, Mylar or polymer materials.  It gives brighter, sharper and higher contrast pictures.
