Nice capture .

You're in a train carriage alongside another carriage. 

The other carriage starts to depart.

The visual illusion is that your carriage is moving.

It can catch you out waiting at traffic lights too if the car in the off-side lane creeps forward a touch making it seem that you are rolling backwards.

Please save the image as a JPEG or PNG file , this way the image will be automatically displayed and members won't have to download it just to see it ... ta very much.

For a wealth of information for beginners I'd highly recommend the "Astronomy and Nature TV" channel.

You'd be better off shooting a hundred or so single RAW frames than using the very compressed video output from the 550D , it's just the Liveview stream captured as a series of small JPEGS.

I used a 14' tall pier at my old address to get 365 days of solar imaging back in the day (2012-2015)

Simply a 100mm x 100mm timber post sat on the patio and braced against the brick wall , it was a bit of an adventure dragging the HEQ5 Pro and Tal100rs up a ladder but it  got me 311/365 so well worth the effort as most folk give up around this time of year.

My cameras a popping out of connection occasionally. I would like a source of quality USB cables in short lengths, do anyone know of any?

Save yourselves the anguish and use the "Oculars" plugin in Stellarium ... 😏

Battling with the poor seeing and gusty wind this morning , disc's OK but the close-ups were too poor to post ... 

"Patience is a virtue ... " and all that ... 😏

Eventually the showers abated and let me have about five minutes of varying views , grabbed 29 frames with not 'too many' clouds and greenery included and ended up with this ...

Here are a couple of pics of my TMB/LZOS 130mm F/9.2. My main reason for posting them is to bump this thread so that folks get a chance to have a look at @stuy's magnificent 228mm F/9 LZOS a few posts back up the page - it's well worth a look - there are very few around, anywhere 😁

 

 

 

Thank you for bumping this John , a thread that had passed me by , a truly astonishing collection of glass on display throughout.

I shall remain happy with my humble new Evostar 150 Achro however , but continue to follow this thread in awe.

First glimpse for ages , hardly recognised him ... 😄

I was very impressed by the Stellalyra dobs at the IAS this year (on the FLO stand) 

The roller bearings made the action silky smooth , much more refined than the Skywatcher I used to own.

If I were after a new Dobsonian it would definitely be the Stellalyra I'd opt for.

Caught a lovely steady 10 minute's worth before it all turned to mush again ... 

And the SDO/HMI Continuum for comparison ...

I had a look last night about 11 p.m. and it was only just clearing the rooftops if I stood on tiptoe. I only had my 200P on it's original Dobsonian mount as the Skytee 2 has gone back for repair. I wanted to capture it with the thin clouds veiling it, but no chance. I did get a great twilight Moon on the 27th, when it was much higher and the sky was clearer, so I'm happy with that until the Moon comes back to the evening sky next month.

Given how low the Moon was last night and how poor the seeing was, I think it's a good image. You've got some nice depth to the bigger craters.

Thanks Mandy ,

It was so splendid just hanging there above the Belt of Venus I couldn't help but point a 'scope at it ... 😉

Thanks Steve but Solar observing has never appealed to me.

It never did to me when I first got started with a telescope , but two completely grey nights/sunny days winters made me get a sheet of Baader film and I was hooked.

It's such a dynamic object that there's always something new to see , especially at the moment when it's so active , there's only so many times you can sit squinting at a faint blurry object that looks exactly the same as the last time you looked at it ... 😉

Or alternatively a good S/H prime camera lens to fit your camera .

Sorry to here this Peter .

I'd suggest maybe trying the daytime side of things and maybe do some solar observing , much more going on on a minute by minute basis to keep you amused and it's much more fun sitting out on a nice sunny day in the warm rather than the cold , dew covered nights you're used to ... 😉

Everything against it really , too early , too low , dreadful seeing ... blah , blah , blah ... but I started so I finished ... 

EOS 6D + Evostar 150 + 2x Barlow , stack of 80 frames.

Interesting how you've ended up with 'limb brightening' rather than 'limb darkening' ... ?
