Not the busiest of days for proms, but I do like the 2.5x Televue Powermate for its ability to zoom in on what little is there!

Solar activity is really starting to ramp up now, and the solar disk is starting to come alive with features - spots, active regions, filaments, filaproms, prominences, plage regions - there's plenty to see.
Nows the time if you have a solar telescope to go out and get a view in - you won't be disappointed!

The sun at CaK wavelengths looks fantastic when there is alot of activity, and today was no exception. Must make a point of taking more of these images!
This was taken with the 70mm frac @ f10, homemade Baader/Coronado hybrid CaK filter and DMK31 camera. This is a result of 6 panes assembled in Imerge.
This has got to be the spottiest sun i've been able to observe in sometime. This image was taken with the 70mm frac at f12, Lunt Solar Wedge, DMK31 and 705nm TiO filter. Despite the poor seeing conditions - the solar disk was boiling away in the eyepeice, the long wavelength and narrow bandpass of the TiO filter cut through the turbulent atmosphere and the image was rock steady on the laptop screen. The TiO filter is worthy addition to any white light observers arsenal, used with a solar wedge and refractor the views are excellent. The filter can be purchased from Omega Optical via EBay http://www.ebay.co.uk/itm/Optical-Interference-Filter-705BP10-25mm-Infrared-Astro-/150612232231?pt=LH_DefaultDomain_0&hash=item2311304827

Today was the first day in what seemed like ages with clear skies, and, as such, I decided to capitalise on it.
There's everything on offer today - active regions, sun spots, filaments, filaproms and glorious prominences. More images to come, stay tuned for updates!
