Jupiter in good seeing

Posted By dan kowall
And it was 'good seeing' this Jupiter.
An excellent image, Alan, superbly processed.

A walk across the Mare Frigoris

Well done, Alan. Now it's time to fill in those 'dark side of the moon' areas.

Another M13!

I don't know if he has adaptors for a C14, but Ted Agos makes focal reducer adaptors for Meade SCTs. He knows quite a bit about focal reducers and you could always drop him a line.
He's here:

To the ones that built a concrete pier... question

Posted By dan kowall
Hi Ivan,
I would recommend pouring a concrete pier base with embedded bolts and using a metal pier on top of that. The advantages are a narrower metal pier and more flexability down the line should you change mounts or want to lower your mount. The disadvantage is the increased cost.
If you decide to go with the concrete pier, I would recommend increasing the diameter to at least 12". Not only would it give you much more lateral stability, but remember that you will need to embed bolts for your mounting plate on top and those have to be spaced in from the edge of the concrete to work properly.
The bottom of the Sonotube can be stabilized by temporary backfill or a frame of boards that are anchored to stakes in the ground. A frame of wood around the top of the tube is stabilized by angled boards attached to outlying stakes.
The most important rule in forming for concrete is to overbuild. Almost everyone underestimates the weight and power of wet concrete.
I hope this helps.

M63

Excellent image, Brian. You've delineated the 'knots' in the galaxy arms and some of the dust clouds are starting to show. The color looks good, too.
F/3? Is this like a Fastar setup or with reducers?

M101

Excellent color and processing, Dennis.
There is a slight gradient in the blue channel as Brian noted. Processing, rather than a flat, will remove that.
It's hard to tell from the jpeg, but it looks like the master subs are misaligned.
Keep up the good work, this is very well done from your location.

Sadr area

Posted By dan kowall
Beautiful color and composition on that image, Mark.
I notice some 'mottling' in some areas. Did you use some sharpening software? A less aggressive sharpening might smooth that out.
Thanks for posting that. It's a really pretty image.
