Here are a few still images captured using an Imaging Source B&W Firewire camera with my LUNT 60 BF 1200 with a Double stacked 50mm.
Winter time down under, so the sun is very low and generally into hazy or light clouds, but with so much solar activity, it is too tempting to take a few shots. The image of the equipment is basically a home built EQ Fork mounted 12" f/5 Newtonian, which in turn supports and ever changing/increasing range of scopes both on top and underneath. At the present, there are four scopes dedicated to solar imaging. Top left a home built 80mm f/15 refractor with an early version (1988) 1 A Ha unit, next a Takahashi FS-102 Apo with a Baader Planetarium Mark IV Solar Prominence Coronagraph-(the only one in the southern hemisphere) I had to wait 18-months for this many, many years ago, but well worth the wait. It has an occulting disc which masks out the entire disc allowing only the rim of the sun to be observed/imaged. This means very faint prominence's are easily visible. This operates without any rejection filter over the front objective. A set of different size occulting cones cover the sun's apparent change in diameter through the year. This scope also doubles in white light with a large Herschel Wedge with various filters (2"). LUNT Solar Systems 60mm with DS 50mm unit. Next far right is a William Optics 90mm Apo used for white light with my own manufactured full aperture aluminised flat (5.25") which I designed and made back in the 1960's. I published an article in the BAA Journal about is manufacture and use well before these were in common use. I just enjoy inventing and making much of my own equipment, 50% of the journey. picasaweb.google.com/109921669020426367250/SolarImagingEquipment?authuser=0&feat=directlink
