+Bino-viewer posted a topic in General Astronomy Discussion,Hi,
Some Astro show dates for your diary's.
European Astrofest 2020 : Friday January 31 + Saturday February 1st Kensington, London. (yes, its early this year !) Links below for full details :
Practical Astronomy Show 2020 : Saturday 21 March 2020 Kettering Show link and speaker info just released below :
International Astronomy Show 2020 : Dates in November to be confirmed. Stoneleigh Park, Warwickshire. Link below to homepage for more info :
After 15 consecutive visits to Astrofest, i have decided to give it a miss this year 😓
Reasons include me being disappointed with the show in 2018 & 2019, the travel involved, as well as 2 other shows closer to home.
But i will definitely be at the PAS in March and almost certainly at the IAS in November as well.
I thought the PAS was excellent last year, and for a first show for them, they hit the ground running and its all for free !!
@Derbyshire Dave : you may be interested in the 'APT' talk ?
Hopefully i'll see some of you there in Kettering ??
Regards, Rob 😀
Nightspore posted a topic in General Astronomy Discussion,I decided on a shoot-out with two conventional 1.25" prism diagonals: a Takahashi TAKSD1 and a Baader Planetarium T-2. The telescope used was an Orion 90mm StarMax Maksutov.
Baader Planetarium Prism Diagonal T-2/90deg and Takahashi TAKSD1
These two prism diagonals were also compared against a third which is a 1.25" Baader Zeiss Amici (also equipped with a helical focuser).
Baader Zeiss Amici
The target was primarily a setting twilight Venus, although I also intended to view Saturn as it was in conjunction with Venus on the 11th of December. I didn’t have much time before both planets were too low so I primarily used an 18mm Astro Hutech, giving 69x. Venus was very bright and easily seen early on with a 25mm AH orthoscopic. For Venus I also employed a Baader Double Polarising filter.
The Tak’ was up first.
It is a lightweight diagonal and I have read reviews stating that the housing is plastic. I'm pretty sure it isn't and is a light metal alloy or possibly aluminium. I'm not so sure about the base plate, but I'm not totally convinced it isn’t also metal. It could very well be be a hard type of plastic. Unlike the Baader diagonals there is no filter thread in the nosepiece. Some have complained about the Tak's plastic collet snagging undercuts. I haven’t had any real problems although it helps if you use smoothies and barrels with shallow undercuts or those with lower lip flares (GSO, Tele Vue). The TAKSD1 gave a bright, sharp image with no light scatter and easily revealed the Venusian phase. The conventional Baader was next, followed by the Amici. Apart from the mirror reversing I could tell no difference between the Tak’ and the Amici. There was no hint of the prism roof with the Zeiss Amici. The Baader Planetarium T-2 also gave a sharp image, although I thought it was fractionally darker.
The amount was almost imperceptible though and may have been my imagination. As Saturn became more prominent I switched all three to that.
I can't choose a real winner. The Takahashi gave a bright, sharp image as did the Baader Zeiss Amici. The Baader bog-standard wasn't really any different and had the advantage over the Tak' of having a helical focuser. The Takahashi and standard Baader diagonals are about the same price.
Al.Grant posted a topic in Comets, Asteroids, Meteors & Meteorites,Meteor detection counts September - November 2019
Although I've not really posted any results, my meteor detector has been running since mid August without too many major issues. It's tucked away in a corner and I often forget it's still running.
I've finally got around to updating my spreadsheet from the data automatically captured by the Spectrum Lab RMOB files.
I had a few problems in September with local interference causing some crazy readings (hundreds per hour in some cases), i zeroed out those that were obviously wrong.
I'm fairly certain some of it was due to heavy electrical equipment being used over the road and in direct line of sight of the antenna.
October and November were both much better with good levels of hits per day and no problems from external interference.
I've seen posts on the RMOB facebook page of people detecting Elon Musk's Starlink chain as it goes over Southern France.
I've checked my captures and not seen anything that I can link to the pass times ...... which is good as I don't actually want them!
Current RMOB data for December: This is live so will update each hour with the latest results.
+Derbyshire Dave posted a topic in Lunar,Very, very rarely do I have a go at the moon, but it was so prominent last night I had a go at 18:30. Plan was to go to an observatory meeting and then come back and go deep sky. When I git back it had all gone ☹️
Still, pleased with this, 500 frames on the ASI183MM through the GT81, processed in Autostakkert and Registax..
+Bino-viewer posted a topic in General Astronomy Discussion,Anyone follow Nasa's 'Astronomy picture of the day" ?
If you don't i thought i'd share todays image with you.
What an amazing object, from the Amazing Hubble Space Telescope !
It's known as Hoag's object or Hoag's galazy.
Its very faint at Magnitude 16 and is located in the constellation of Serpens, and is a mere 600 million light years away.
It doesn't have NGC classification and is listed as PGC (Principle galaxy catalogue) 54599
If only i could see something like that from my own telescope ?!! 😀🔭
