I think you don't need 500 stacked frames for the sun! Here's one I took single frame using my ETX-125 and Thousand Oaks filter.

Martin,
Be careful using the ETX for solar viewing. I used a Thousand Oaks on an early ETX 90 and ruined it. The baffle on the secondary is stuck on with a glue ring which got hot and melted.

After taking a break, I went back out peaked through the eyepiece to a horrible mess. The baffle had slid down the secondary leaving a trail of glue.

I'm not positive but I think the ETX 125 is done the same way.

John

I cut the aperture down behind the Filter to 1.5 Inches using a piece of card

Martin, the melting glue problem has happened just sitting out in the sun. My ETX 90 did it while I was inside and it wasn't even pointed at the sun. It has been known to happen to the 125s as well. It would be wise to limit the amount of exposure and cover the scope when not in use.

Of course, this time of year it probably won't matter but in the summer it probably will.

Good start on what I'm sure will become a lifelong obsession ... just like all of us! ;)

I mainly use my ETX-125 for visually observing the sun with a Baader solar filter. It performs exceptionally well in this task!

However, it also does a great job when used for imaging the sun. For this, I'll use my DSLR with the Baader filter. I'm always amazed at the ultra sharp and high contrast views this scope can produce. Here's a shot I took of the sun during the Venus transit on June 5, 2012.
