Up for sale is a DayStar Quantum PE 0.6A H-Alpha solar filter with Tele Vue 4x power mate. The filter has just recently returned from DayStar check up (October 2017) and replaced with brand new block filter. It then carries another 10 year warranty, which is transferable to the new owner.

The filter is in very good conditions, both mechanically and optically. In fact the optical parts should be regarded as near new condition. The power mater adapter show some faded anodized color, which was originally like this when I ordered them new from DayStar.

The power mate was purchased new from Televue and is in near MINT condition, no dust no scratch on the lens. Just a little tiny set screw marks on the 2" nose piece.

DayStar filter needs F30 incoming light beam. The 4X power mate helps achieve such requirements when used on a F8-ish scope. The power mate adapters attach the 4X power mate lens and eyepiece holder tightly with the DayStar filter housing without tilt or sag and reduce the total light path and keep the whole assembly in a compact profile.

The filter has a 32mm clear aperture (comparing to Quark's 19mm clear aperture). Full solar disc is achievable with 800 focal length using 55m TV plossl. The PE grade has very high uniformity across the whole FOV than SE grade or the Quark. It is aimed for professional or research use, or for very serious amateur solar observer/imager. 0.6A bandwidth shows good balance of surface details and the prominence. See attached photos that I took. No aggressive processing applied and they quite matched what I saw at the eyepiece.

The sale includes the following items:

1. Quantum PE 0.6A h-alpha solar filter
2. Televue power mate adapters
3. Televue 4x power mate
4. 12v DC power adapter

Price is 4000 dollars, plus shipping. Buyer takes care of PayPal transaction fee if used. Sale is CONTUS.
