Solar FinderWhilst the amateur astronomer is well used to being ripped off outrageous prices for 'simple bits of metal' (see, for example, camera adapters, spacers and 'par-focal' rings) the ultimate insult must be the prices demanded for a bit of bent metal** with a hole in it known as a 'Solar Finder'.**A more 'up market' version is the Televue "Sol-Searcher" Solar Finder = essentially two pennies with holes in them bolted onto a bar (finder 'scope mounting extra).Apart from the price, the common problem with all these devices is that they require you to remove your existing finder scope = which of course means re-aligning it when you put it back on !So why not simply fit a filter to your existing finder scope instead ? Well, if you thought 'solar finders' were a rip off, you should try buying a solar filter !The DIY approach of making your own filter (using solar film, available by the highly expensive sheet) is not much cheaper. Anyway, I'm never been happy with risking my eyesight by looking through a telescope with a filter that can be removed, plus, of cousre, if you are using 'sun projection', chances are you can't get your eye to the finder scope position anyway.I thus took a look at modifying my existing finder by drilling a hole in it's mounting bracket and fitting a 'screen' (bit of not-100%-dense white plastic - or oiled (to make it translucent) paper in a Sellotape 'sandwich')
