Baader Herschel Prism

[tbyork2012]

Hi,
I've recently bought the Baader Herschel prism, to see if I could get better details of the sun in white light. The link is to the unboxing and first images I managed to get of the sun.
Herschel prism in its case:

I shall be doing more posts on this with comparisons.

What sort of scope are you using? Does this take the place of using the typical solar filter in front of the OTA?

 

[tbyork2012]

I used a Skywatcher ED80 refractor. You do not need any solar film in front of the scope, as 96% of the light goes to the ceramic tile which dissipates the heat. The remaining 4% is directed to the Baader Solar continuum which needs to be the filter closest to the prism, as it will reflect most (but not all) of the IR away and prevent most of the heat getting through to the eye piece or imaging system. Hence it is fairly safe. But it is not for use with reflectors though.

Very cool. Appreciate the info. I'd love to see the results when you get a chance.

There are two initial images of sunspots taken with the herschel prism at the end of the unboxing thread above if you are interested.

Hi,
I've just posted my comparison between images captured with Baader Solar film vs Baader Herschel Prism here: http://myphotojourney.co.uk/baader-herschel-prism-vs-solar-film/
There will be more comparisons to follow over the next few days.

Hi,
This is a comparison of single vs double stacked Baader Solar continuum filters. http://myphotojourney.co.uk/baader-herschel-prism-single-vs-double-stacked-solar-continuum/
I'll let you be the judge of whether there is any significant difference.
