Hi Rob,

Hi Jessica!

Interesting! Looking forward to reading about your experiences with it.

Does this help?

Wonderful images Peter!

I'd want a Morpheus 17.5 to use it with five or so telescopes ranging from 500 to 3000 mm.

There are 42 ways to clean your glass.

Has great presence, yet looks so delicate. Just beautiful!

Very detailed, really good!

Ooh, I like that!

The f8 would be better on planets. It has less coma, less curvature of the focal plane and can be made with a smaller secondary (not sure if this is actually done), which means a smaller central obstruction. The f5 gives wider views with less magnification using the same eyepieces and would be more of a rich field telescope.

What's your budget? Here is an idea (£136): https://www.firstlightoptics.com/beginner-telescopes/skywatcher-heritage-130p-flextube.html You may need an extra eyepiece or two. This program can help you select targets: https://stellarium.org (free for computers, very affordable for phones)

The pictures show the problem well. I hope you have the three knobs that are needed to hold the mirror cell in place. Together with the screws that are still in place, you use them to adjust the tilt of the mirror. Check Youtube to learn how to collimate the optics. Here's one of the many instruction videos on the topic:

Good image. Congratulations!

Two landers and all sorts of terrain. It's an interesting image. Sharp and detailed. Thanks!

Good seeing yesterday night. I spent some time on the Moon after it cleared the trees. Maurolycus captured my attention. Here's a painting of the scene:

It's a wonderful sketch Achim. My plan is to avoid the Sun altogether in the next few days. 36-39 °C is too hot for me!

Ooh, that's a nice telescope!

Good choice! The XWs have an excellent reputation.

I can only compare Morpheus 6.5 (76°) to Delos 8 (72°). In a flatfield f/5 refractor, considering that the M6.5 gives 23% more magnification than the D8: Sharpness is very similar. Both are excellent in the centre 72°. That's where the view stops for Delos. Outside 72°, Morpheus 6.5's sharpness gradually drops toward the edge. Delos is slightly better. Contrast is very similar. Excellent in both. Pincushion distortion is low in both. Morpheus is slightly better. Eye relief is copious in both. Non-eyeglass wearers may prefer to use a raised eye cup. Comfort is equally excellent. Both have well defined exit pupils and in both the entire afov is easily seen at a glance. The M6.5 is more sensitive to seeing conditions than the D8 due to its higher magnification, so the stars may actually look sharper in the D8. In good conditions against terrestrial targets though, both eyepieces seem equally sharp to me. Based on other focal lengths, I'd say that ES 82 with their short usable eye relief are less comfortable than Nagler T6 and much less comfortable than the Morpheus. In ES 82 can't see the entire field at once, and my eyelashes frequently brush the eyepiece. With NaglerT6 I don't have these problems. Also, Naglers look sharper to me, over the entire field and especially at the edge. Morpheus are more like Pentax XW and Delos (long eye relief eyepieces) than to ultra wides, which tend to have (much) shorter eye relief. If you want to go 82°, there is also the 7mm Skywatcher Nirvana / WO UWAN which may be better than the 6.7mm ES 82. My 16mm Nirvana is very Nagler like.

Mike, that's awesome! I had to try this. I'm much too impatient to attempt dotting by hand, so I used levels, pointillise, desaturate and posterize in photoshop. I tried twice. The coarser one looks better to me. The zip has the original and two pointillised versions. Hevelius pointilised.zip The work took no more than minutes, but looking at your result I have hours of experimenting to do before I can expect anything as good. Great job!

It's special. Tumbleweed nebula. Great image!

Special! Thin clouds and a blue sky add a great deal of atmosphere to the eclipse.

Lovely photos! Thank you.
