I came home late at 22.00hrs, but it was still clear, so: I quickly went outside with my 90mmF10 grab-n-go refractor. Here's the observation list:
Temp: 0.8gr.C. Seeing: average-fair
M42: beautiful deepsky object. At 112x sides of the "sword" become visible after looking periphery.
M1, FINALLY, I was searching for this object for a long time. At 28x it was visible as a weak fuzzy dot (with 32mm Televue Plossl). The strange thing is that looking periphery doesn't show more details. When I look with the 21mm Hyperion (at 42x) I cannot see a thing....
M67 Big open cluster. It just fits the field of vision of my 32mm.
M45 Pleiadels. It remains a true joy to observe this bright open star-cluster. At 28x it does not fit my field of vision completely.
Melotte 25 Hyades. I still find this open cluster a little bit arward.
And, last but not least:
NGC1647: A truly beautiful open star cluster. By looking periphery more and more background stars appear. It just fits my field of vision at 28x.
My 32mm Televue plossl is becoming a real -workhorse- for my 90mmF10 refractor. I am still amazed on how many deepsky objects I can see with this small 90mm refractor (that is really my astrophotography guidescope) with 32mm Televue plossl :D.
It has its charm, normally I am busy with an enormous amount of cables, laptop, interfaces, aligning, goto, focusing, flat-dark-biasframes etc. Just grabbing your 90mmF10 on EQ2 mount and start observing also has its charm. It doesn't have to be all high-tech to enjoy this beautiful hobby!

Night out with the small refractor
Now and then I also like to go out with my small 90cm refractor. Especially on nights with clouds and danger of rain (in this case snow!). When it starts I am inside with the telescope in a few seconds. I am always amazed how many beautiful things that I can see with this small telescope. Here is the report of last night:
Outside temperature: 1.5C with 90cmF10
M45 Pleiades (7 sisters): very beautiful in the 32mm Televue plossl (at 28x all stars in vision)
M57: Ring nebula in Lyra. fairly visible with the 8mm Hyperion (at 112x)
M36: Open star cluster in Auriga. Nicely visible with the 8mm (at 112x)
Melotte 25: Hyades open cluster in Taurus Hyaden. Nice with 32mm (at 28x)
@2057hrs a bright meteor showed up. It went from Casseiopeia into Hercules with a long white line behind it which glowed for 1sec. At the end, just before it went out, it showed a small sidewinder.
Then the clouds came and I had to go inside. At 2300hrs it was bright again, the session continued:
M42: Orion nebula, nice at 8mm (112x). Central trapezoid star cluster well visible.
M81 & M82 Galaxies in Ursa Major. Both visible with the 21mm Hyperion (at 42x). Separately also beatiful with the 8mm (at 112x). M81 shows with a central bright dot and a faint nebula around it. The cigar-like shape of M82 is also clearly visible.
All-in-all a nice night out with the small refactor!

Many clouds so working with the quick peek scope
The last weeks there are many clouds in the evening, and also a big chance for rain. So carrying in/out the big 200mm Newton is a lot of work. I decided to put the 90mm F10 guidescope on my Gitzo photo mount, and it works perfectly. This evening, with even many clouds, was a fruitful night out. I saw M31 (andromeda nebula), M45 (pleiades), comet 17P/holmes, mars, M29 (open star cluster in cygnus), M57 (planetary nebula in Lyra, very very faint), m43 (large nebula in Orion), as well as the Alcor/Mizar double star in Ursa Major (big bear) and Beta Cygni, a double star in Cygnus (swan). So that's not bad for a refractor evening. Makes me think back of the times when I was young and was out there with the borrowed JWG 60mm telescope of my nephew. With this 90mm refractor I can see a lot more however, but not as much as with the 200mm Newton.
