Poor seeing and naked eye Faculae... Tal2 Vs Tal1.


This morning's solar image taken with the Tal2 reflector.

Not much photographic detail I'm afraid.

The atmosphere wasn't in a cooperative mood, although the naked eye view did reveal the presence of faculae detail around active regions 1820 & 1830.


There was also faculae detail to be found some 180 degrees further around the solar limb.


Considering today's poor seeing, I was pleasantly surprised at how well the faculae stood out.

 Solar imaging...... Tal2 verses Tal1....!


These past few months most of my solar images have been taken with the Tal2 Newtonian. 

But is the Tal2 the best scope for solar imaging..?

Tal2 is delivering some lovely views of the night sky, but I'm not sure its up to scratch for day sky imaging. 

Often I blame the seeing for the lack of solar detail, but maybe my choice of scope is not helping.

My 4.5 inch Tal1 reflector over the past two years, has consistently returned some lovely solar images.

I'll very soon have to wheel out Tal1 to make some comparisons...



Below is an image taken with Tal1..... just over a year ago:


Taken with: Tal1 4.5 inch f7.3 reflector

 The Faculae can clearly be seen in this photograph.


Maybe Tal1 is better, compared to Tal2 for solar imaging, or maybe it's just simply down to the atmospheric conditions... !

I'll have to keep experimenting ......

Clear Skies

Mark.
