Dennis, that's a nice image but note that CN will resize any post that is over 1200 pixels in height, so what you got is only 1200x1200, not 1600x1600. You can, however, post images that are 1600 pixels in width, but the height can't be over 1200.

 

The largest size that is possible (or allowed) for an inline image is 1600(w) x 1200(h).

Thank you James, I misread/misunderstood the image size guidelines, so thanks for clearing this up, I appreciate it.

Here's one of the hand-held photos that I took on Friday morning of the 94.6%-illuminated waning gibbous Moon using a Canon PowerShot SX720 HS camera.

Here's an image of the Moon that I took on Monday night using my Seestar S50.

Very nice… how are you liking your SeeStar? A friend of mine loves his…

This was from last year, during the wildfires.  Had a spot of less dense smoke but captured the yellowish tinge in the sky.

 

AT130EDT at native FL, with ASI585MC

Our Moon as seen from Brisbane on 30th April 2024.

 

I used the Canon RF 200-800mm (at 800mm) with the RF Extender x2.0 and the EOS R7 on my Tak EM 200 Temma 2 mount. The Moon pretty much occupied some 80% of the view finder of the EOS R7 camera.

 

I used the built-in Interval Timer to take 75 frames (1 sec delay). The 75 Frames were then Aligned and Stacked in Autostakkert4! followed by sharpening in Wavesharp.

 

1600mm, F18, ISO400, 1/60 sec.

 

Dennis.

Dennis, that's another nice shot. But, do you know what caused the pale red, moderately wide, band along the upper limb of the moon (worse on the top and left limb -- not the terminator)? Could it have been from some chromatic aberration that you tried to correct?

Good pick up, the red colour tint it was not something I noticed until I went back and had a closer look at the full size, full res image.

 

After the Align/Stack of AS4! and Wavesharp deconvolution, I took the results into Photoshop and used the Auto Tone and Auto Colour function and I am wondering if that caused the red band?

 

I wonder if "fringing" during the Alignment process might also cause some image registration artefacts that have also contributed to this?

Here is an afocal photo that I took yesterday evening of the 7 day old Moon (First Quarter). It shows the terminator from Stöfler down to Manilius in the Mare Vaporum (south is at the top). Photo taken through my Orion 6" Dob with 15mm eyepiece (80x). 

 

The big shadow filled crater at top (south) is Walter. There was a small starlike object within the shadow, namely the very top of the eastern peak just catching the sunlight. It was a perfect evening for viewing the many rilles in the area north (bottom) of Hipparchus; Rimae Hyginus, Ariadaeus, Triesnecker, Sulpicius Gallus, Reaumur and Oppolzer. You can also, just about, make out the Abulfeda crater chain.

 

Both the Lunar X and Lunar V are also visible.

Another afocal photo taken yesterday evening through my Orion 6" Dob, again through the 15mm eyepiece (80x). Again, south is at the top. 

 

 

It shows one of my favorite lunar areas, the junction between the Mare Serenitatis and the Mare Imbrium. Hadley valley is in deep shadow but the Rima Fresnel can be seen west of Prom. Fresnel. Not clear in the photo, but the rille bisecting the Alpine Valley was well seen last night using 200x. I always enjoy just visually exploring the 'orange skin' region east of the high Alpine mountains that reach towards the Egede ghost crater, composed of thousands of mountains and hills and also the huge 'splash' of the Montes Apennines which heads southwards towards the Mare Vaporum. East of the Montes Haemus range you could, just about, still see the big Valentine dome, not readily visible in the photo though. Between Atlas and Hercules and Aristoteles and Eudoxus lies the spooky Lacus Mortis and the crater Bürg.

I took these hand-held afocal iPhone photos on Monday night using my 6" Orion SkyQuest XT6 Dob.  The trio of prominent craters consisting of Theophilus, Cyrillus, and Catharina was well placed at the time.

These are some of the hand-held afocal photographs that I took on late Wednesday night/Thursday morning using a 6" Orion SkyQuest XT6 Dob, and either a 25mm Orion Plössl or a 25mm Orion Plössl with a 2x Orion Barlow lens, and my iPhone.

 

The Lunar V and Lunar X were past their prime but were nevertheless still visible, as were Aries' Hoofprint and the Lunar X3.

Do we included Seestar S50 images here?

1 minute video stacked to create this image.

Here are some of the hand-held afocal iPhone shots that I took on Thursday night with my 6" Orion SkyQuest XT6 Dob, a 25mm Orion Plössl or an 8-24mm Tele Vue Click Stop Zoom eyepiece.  The Straight Wall (Rupes Recta) was visible but was past its optimal illumination.
