M27 in OIII (May 5, 2017)

Here is M27 in OIII.  This picture is a stark contrast from the H-alpha.  The OIII emission is mostly what we see when we look at the nebula, which is very bright.  My most memorable view of it was from very dark skies in Idaho through an 80mm refractor.  Under such skies, M27 looks like a cotton ball hanging in space.  This is 8x720" with the SXVF-H9 through an Astronomik 6nm OIII filter and the CFF 290 Classical Cassegrain.

Lunar Crater Copernicus (May 5, 2017)

Here is Copernicus.  It is a stack of 5,000 frames taken with the ZWO ASI224MC through the CFF 290 Classical Cassegrain at f/33.75.

Luna: Bullialdus Crater (May 5, 2017)

Here is another crater, Bullialdus.  One striking thing about this image is that the it's hard to tell what the inner peaks look like from the top, but the shadow reveals two triangles with perfect sides.  This is 5,000 of 20,000 frames, stacked in AutoStakkert! 3, taken with the ZWO ASI224MC through the CFF 290 Classical Cassegrain at f/33.75.

Luna: Reinhold (May 5, 2017)

This is best 3,000 of 20,000 frames, processed with AutoStakkert! 3 and Photoshop Elements.   The data was gathered with a ZWO ASI 224MC camera through the CFF 290 Classical Cassegrain at f/33.75.  This one was pretty fun to process.

Jupiter at 3:31-39 UT, May 6, 2017

It's been a while since I tried this, but planetary imaging is kind of fun even though I'm not that good at it yet.  I thought the seeing would be better tonight, but the air did not settle until after midnight, when Jupiter was behind the trees.  This image is 40% of its original size, as a result.  It is 10,000 of 20,000 frames with the ZWO224MC camera through the CFF 290 Classical Cassegrain at f/33.75 (TV 2.5x Powermate).

M27 in H-alpha (May 1, 2017)

I've shot this target before, but never at this focal length in H-alpha.  What intrigues me about this image is the motion.  You can almost see the swirling of the central star as it shoots out energy—something is certainly spinning out radiation.

This image is 9x720" through an Astronomik 6nm H-alpha filter and the CCF 290 Classical Cassegrain (at about f/8) with the SXVF-H9 camera.
