yesterday afternoon, the forecasts for the evening were good so I set up the 10" truss-tube Dobsonian on the terrace for cooling down. Actually in the evening the sky wasn't as clear as expected but the cirrostratus luckily did not harm too much. It could have been brighter but anyway ...
So I tried my new 2x focal extender with the 10 inch scope for the first time and magnified up to 370x. Seeing was okay and I really enjoyed travelling along the terminator from Plato via Copernicus down to Clavius. For the 10"er the focal extender is really an enhancement when viewing the moon and conditions are okay: I saw much more detail in Clavius as I have ever observed before.
This would have been a good sketching target but finally I decided to go for a sketch of the magificient Copernicus (named after the famous Polish astronomer by Giovanni Riccioli mid of the 17th century):
The crater floor was still completely in darkness, one could only see the bright, round rim of this 93km wide crater. The terraced slopes were just partly in the lunar sunrise yet. Obviously the central peaks are as expected lower than the rim - they were still hidden in the darkness. The two craters north of it are Gay-Lussac A and Gay-Lussac on the way to the Montes Carpates with their eastern parts already visible.
Here's the sketch:
Telescope: Martini 10" f/5 truss-tube Dobsonian
Eyepiece: Explore Scientific 6.7mm/82° with Explore Scientific 2x focal extender
Date & Time: Jan 22nd, 2021 / 1900-2000 CET
Location: home terrace, Dusseldorf region, Germany
Technique: Koh-i-Noor charcoal, whitecoal and chalk blocks and pens on black sketching paper
Hi, I have recently bought and mounted a third version of a weather monitoring station, this time a non DIY product - The Lunatico AAG Cloudwatcher and the Solo computer with it.
I have been running a weather monitor for five years now, but because i lack front-end coding (or hasn't taken the time learning it) I have been looking for a out-of-the-box product which presents the data in a nice way.
The difference between this product and the two other models I have made earlier is the raspberry pi and the webserver capability.
The earlier versions hade the capability to output a "safe" or "not safe" command to my sequence program.
This version from lunatico has the capability to output a folder in my network with a boltwood textfile, or direct via ASCOM.
So far, i have been running this for two weeks now and it is working very nice. The data is presented on a webpage very nice and it has 100% uptime as of now.
Just one time, the cloud temperature has been presented wrong, this happend during a weather change from +2 degrees celsius and overcast to about -10 degree celsius with clear sky in a matter in a couple of hours.
please feel free to comment and ask questions
Hi I went out this early evening to see if Saturn and Jupiter were observable but the clouds dominated this area.
The Moon however was in a very clear area so I used my MeadeETX90 with a bino viewer with two 25mm eyepieces and spent some time viewing it.
The views were really good as the Moon was in the first quarter which is when I feel is one of the best times to view it as it is not to bright.
The shadows that were being cast were amazing but once again the clouds rolled in so until the next time??
So I originally planned to go to a good vantage point from the top of Pendle hill, watch out for witches whilst there. It is a local and well known Lancastrian landmark. However my wife is recovering from hospital treatment and so I didn't want to leave her so made do much closer to home.
A short drive (2 minutes) took me to a place aside the motorway slip road but with a clear-ish view of the setting planets. I was only use 10x30 bins so the view was not particularly well defined but still impressive when considering distances and such.
Anyway it is in the bag but would like to do better if at all possible.
If the skies are more obliging tomorrow I may venture out with the EEVA set up and grab some data, however the forecast is not so good.
