This is at FULL resolution ... resample to 50% and it looks YUUUMMYYYYYY !



This suggests that a hybrid result such as HaLRGB would be debatable. In

other words, strictly narrowband and those really fake photos?

Your image has a lot of small faint galaxies scattered about. It would be

interesting to see what you could capture with a large format CCD.

The side away from the bright star is particularly richer with the very

small fuzzies. I really like what the RHA can do ... you are looking at

the average combine of 30 one-min subs with full reduction and DDP.



I will go back at it again tomorrow with hopefully darker skies. There

was some very low-level haze last night and I do not know if it helped

illuminate the sky.



My seeing right now is good and characteristic of this time of the year.

I remember for the blue subs having a FWHM of around 1.4 pixels with my

four-second guide exposures. The green subs had an FWHM of around

1.6.Tonight is also similarly good as far as I can tell visually.



Anyway, my three primary targets for Hercules right now are M13, M92 and

Abell 39 and which I would like to get out of the way certainly this

week (one evening per target). I will also check on the apparent

diameter of the Hercules galaxy cluster in the event I can do something

(RHA-ST10XME @ 46'x31'). :-)

That is an impressive M13. Was too enamored with it to notice the gradient

until someone mentioned it.

Hi Scott,



A remote observatory is something with very low probability. I am one of

those who likes to be hands-on right beside the equipment and under the

sky when imaging for various reasons. I realize for some it is the only

means to be active in this hobby and I both understand and apprecate

this means to an end. For me, however, I really like to watch and

supervise the equipment while it is doing its think, to examine each sub

after it downloads, to look up at the sky once in a while etc.



A worse case scenario for me is a change in focus ... h-alpha solar

imaging, planetary imaging, lunar imaging, photometry and esp.

exoplanets, landscape astrophotography etc but DSO work is my passion

right now!



Anthony.
