I love that area of the moon. Here's my best image of the #BayOfRainbows taken with an #ETX90 telescope.

Lots of my favorites in there. Here's #Clavius a long time favorite captured with my compact #ETX90

Ohh, #Eratosthenes , one of my favorite craters. You've captured it well.

Here's my best attempt with my #ETX90

One of the real trouble jobs in #astronomy is collimating a reflector telescope. In particular, Maksutov-Cassegrains, like the ETX90, are tricky.

Fortunately, Escher over Cloudy Nights has posted a really useful guide.

The #Aristarchus region is interesting for a number of features, but the Crater itself is in fact very bright.

Here's a view of the region taken with an #ETX90 telescope.

I love the Aristarchus region. For the longest time I thought there were two rills trailing off from the Crater. I finally realized that one was actually shadow cast by a difference in terrain height.

Here's a shot of #Aristarchus taken with my #ETX90 some years ago.

I put to you a challenge. Here's my best #ETX90 photo of Copernicus crater. Have you taken one with your 80ED? It would be interesting to compare a 90mm #Maksutov #MoonPhoto with central obstruction to a clear #aperture #80ED.

That's a very sharp image. It shows the superiority of the #C8 over my modest #ETX90. But just for the comparison, here's my ETX 90 version of #GassendiCrater.

I bet that Skywatcher is great for high resolution targets. Even my little #ETX90 does an admirable job on #SolarSysyem objects and #DoubleStars. For some years I thought about getting a 125mm Mak, but settled for an f/10 6 inch planetary #dob.
