What does &quot;good seeing&quot; mean?

	*  The atmosphere is a complex and ever changing mass of air which can drastically affect how well you can see with your telescope. To the naked eye, on what would appear to be a clear night, stars and planets might look just fine. But through a telescope, focusing may actually be next to impossible.</description>

introduction

	* there is a surprising amount of gear one needs for general versatile walkaround photographic kit when you do not quite know what you will need
	* you should avoid taking too many options as this often results in poor image quality as you can't make your mind up - I often only take 2 or 3 lenses to reduce this issue</description>

My firmware requests to Olympus:

	*  #1 wish:
		*  all cameras with live preview:
			*  please give us an acoustically silent mode with zero shutter lag:
				*  this would be easy to implement just don't drop the mirror down in Live Preview mode if camera is in manual exposure mode and a manual WB mode as in these cases there is NO need for the mirror to drop down.</description>
