Sunny Petts Wood

Hello All

Hope you are all keeping well - and Happy Easter.

A couple full discs in mediocre seeing from Petts Wood.  Not much going on in terms of spots but always something to see on the limb:

On 4 April, Ha only:

Nice.  You are very versatile Roberto, Deep Sky, planets and Moon and Solar, plus mosaics.

Hi Richard

Thank you!  Prominences are always great - many times they look better visually than in a picture I must admit.  When the Sun is at its most active, they can come in beautiful shapes - see this one from July 2012 also taken from Petts Wood:

Hi Roberto
I was looking at these through my modified PST (80mm) and the large Prominence looked brighter than the small ones.
But the PST dose have a sweet spot, so you have to move the scope about then the Prominences come in and out of view. Very nice images.

Thank you Julian.  The PSTs are excellent scopes for their size.  Many people have taken the etalon from those and paired them with a larger objective to increase the resolution and eliminate the widen the sweet spot to cover the full disc.  An option if you are inclined to fiddle with optics.

Another cracking set of shots!

And that July 2012 prominence is stunning.
