PST Safety warnings and modifications. UPDATED
Posted 28 August 2006 - 08:56 AM
The PST is a very specialized instrument and any changes to a scope like this could be extremely hazardous. Changing the spacing between the Etalon and the diagonal (which contains IR blocking) could result in the light path changing and more energy reaching the eye. The damage would be done without any physical warning. Also, there is a risk of the modified scope breaking or shifting, even parts of it falling off while viewing.
I would like to add that one of our main tenets here on Cloudy Nights is that we are a family oriented site. With this doctrine comes certain responsibilities that we take seriously. Safety is one of them. Cloudy Nights will not host any discussions or threads that have to do with modifying these telescopes for solar observing. This includes images and discussions of disassembled PST's.
Please respect the position we have taken and abide by it.

In keeping with our policy concering PST mods, we will not allow users to refer to their altered PSTs as PST80 or whatever. It calls attention to the fact that it has been modified and is outside the spirit of our rule. Such posts may be edited or deleted by one of the moderators without warning or explanation. Once again, we have been advised to do this by our legal experts to minimize any liability to Cloudy Nights and it's owners, Astronomics. If you are not clear on this please PM a Moderator or Admin for further info.

A quick Question Don... Does this also refer to what Denkmeier is doing now with the PST? I don't really feel comfortable even with this.
Why should that worry you? They're not a bunch of kids messing around in their dad's garage.
I've got one coming and I really look forward to it.

A contributor (not me) has just had images taken with a modified PST deleted. Not images OF a modified PST ... which is what the wording seems to forbid.

Quite honestly, what is the safety issue here? Should we be banning white light images on the grounds that they might encourage people to observe the Sun without "modifying" their scope i.e. adding a safe objective filter or a solar wedge & neutral density filters?
It's heavy handed moderation like this that makes me wonder whether I should continue contributing to this forum.
