Great info John - thanks !

I'm not really into solar observing; but, I must admit that from time to time, I would like to have the equipment to take a look.

Another option would be a DayStar T-Scanner. The 0.6 Angstrom model runs around $2600 minus the Energy Rejection Filter (ERF) and the telescope. The f/30 requirement can be met by using a 2x, 2.5x, or 4x Tele Vue Powermate to extend the focal length of the telescope, or by stopping down a larger aperture. The advantage to the T-Scanner is that with the proper ERF size, the filtering system can be adapted to an aperture that is significantly larger than the 40mm PST. Clear skies to you.

Nice article John!
I made the same mistake several NEAF's ago. I took a look outside the side door to check the weather and there he was - the Coronado guy, luring passerby's. He asked me if I would like "a piece of candy" (to take a look) and I said - "no, it will cost me too much money". But after a few WOW's from other unsuspecting attendees who had already taken the bait, I found myself with my eye at the eyepiece. Hook, line and sinker - the rest is history.

When we are taking about these great filters, theres something missing. Copenhagen Astronomical Society has a 0.5Å University filter from DayStar (1996). We has used this magnificent filter on 8", 10" 11", 12" and 14" SCT telescopes. Thats aperture from 2,5" to 4,50" with an ERF multiadapter. On good days (god seeing) the views from 2,5" to 4,5" is so much better, that you just can't believe it!! The main reason behind my new (Vic Winter) Daystar 0.6Å ATM filter is aperture. A SM60 is much easier to use, but aperture rules in my world.

/snip/ On good days (god seeing) the views from 2,5" to 4,5" is so much better, that you just can't believe it!!



Hey Lars... is that a parapraxia, or are those filters that good?

If the seeing is good, then the views in the filters are indeed *very* good (especially those with passbands of less than 0.7 Angstroms). I use a 3.5 inch aperture ERF with my DayStar T-Scanner, and there have been a few days when I wished I had just a little more aperture. My PST still gets the lion's share of use on the sun, but occasionally, the T-Scanner will show things at much higher scales and in far more detail than the PST is capable of. Clear skies to you.

I apologize David... my reply was tongue-in-cheek to Lars' misspelling of 'good' as 'god'. (A parapraxia is also known as a Freudian slip.) :crazy:
