On Thursday morning I will be aiming to get a full solar globe set of images using the meade 6.3 reducer on the Orion ED80 and I've suddenly realized I don't have a 2" IR/UV filter to fit my 6.3 reducer and have no way of converting it to take my current 1.25: filter to achieve correct colour balance.
My question to my learned colleagues is, will the Baader Solar Film perform a similar function. It is after all designed to keep out harmful rays.
I believe that you will still require an IR blocking filter based on my experience yesterday, Monday, as follows:
I had the BAADER AstroSolar™ Density 3.8 Photographic only full aperture filter on the Vixen 4 inch and was experimenting with a newly acquired BAADER Solar Continuum filter.
I removed the BAADER UV/IR cut filter from the ToUcam and replaced it with the BAADER Solar Continuum filter (designed to enhance the visibility of solar granulation and sunspot details). Well, the image was a mess; a big bright blob that would not resolve into any detail in spite of adjusting all the settings in K3CCDTools.
I then re-fitted the BAADER UV/IR cut filter and this made a significant improvement.
A little puzzled, I browsed the web and found the following at the Adirondack website:
“For digital imaging, we also recommend the Continuum filter be combined with our UV/IR Cut Filter (to completely cut the defocused far infrared wavelengths)”.
So, I suspect the answer is yes, you do need a UV/IR cut filter as well as the BAADER AstroSolar™ filter.
why do you need the 6.3 focal reducer paul, the sun would be too small in the ed80 with it in?as for the uv/ir, yes you need that, even that contrast booster they talk about
Yeah Paul - why use a reducer? I actually fitted a x2 photographic teleconverter to my WO 80mm f7 and the Sun filled the frame as seen below.

Alright Mr MyDUstMoateIsBetterThanYours what way was the pentax oriented when you took that, it looks 90degrees out when compared to the "official" format. only asking because can use the sunspots to reference NSEW and position better for the initial entry Love the image scale too - awesome.
SO who can ship a uv/ir cut 2" filter in less than 24 hours.......................
I've been doing a bit of thinking, and I might have a way out of it. I have a 9X50 Stellarvue finder scope similar to yours. I could remove the eyepiece from that and put the SAC/ToUcam in there. If I can get it to focus, possibly with a barlow my problem could be solved. I'm still going to be imaging with the 8" and the SAC/ToUcam so I'll get some closeups. Hmmmm I'll have to snaffle my DSI IR filter to use on one of them. I hope it's fine tomorrow and my lovely wife feels like playing sorcerers apprentice again
