Hi all,
Does anybody have scans of blocking filters made by Coronado, Lunt and Solar Filters ?
Or where may I see them in the Internet ?
Thanks for help.
Valery.

Re: Band pass of different blocking filters.
I've only seen published data on the Coronado - there's a copy in the files area.
I don't think anyone has done a similar examination of the Lunt and Solar Filter BF.

Mark,
A great resource which unfortunately is becoming dated ( last update 2008?) and doesn't include any Lunt, DayStar or Solar Filter info.

Yes, a shame there couldn't be more updates, still, it is a very valuable reference and certainly one myself and no doubt countless others have referred to many times.

Hi Valery
yes it would be of great interest to see plots of all those blocking filters done by one good instrument
