Venus

[ags_]

Hi,
here are my Venus images from the last 3 days captured during the late afternoon in variable seeing conditions using an Astrodon UV and a Thorlabs FELH1000 filter.

Regards, Phil

Really great detail Phil, really impressive.

Thanks Trevor, the Japanese JAXA team are looking at the dark circular area , it's possibly an equatorially-trapped Kelvin wave but doesn't really fit their known data.

Just had an email from the Akatsuki mission team they are going to try using the LIR camera which uses thermal emission sensors and can track the dark spot over the night side if it is heat related. Interesting planet Venus with it's heat and sulphuric acid clouds which charge across the surface right to left.

Awesome images Phil. Love the detail shown.

[Atmos]

The best views I've had of Venus so far! Such a boring visual light planet.

[kkara4]

awesome cloud detail there Phil :)

Three more sets taken 12th,13th,14th again the seeing was very variable, it is cloudy and raining today so catching up with household chores.lol

[silv]

wow! you sure you haven't mixed up Jupiter and Venus? Great detail.

[Regulus]

Exceptional imaging of an otherwise mundane subject.

These are from the last week, again very variable conditions but some interesting upper cloud detail.

Cheers, Phil

The 1000nm filter is certainly paying for itself this week

[Derek Klepp]

Those latest editions are really impressive.Thanks for the updates.

[Kunama]

Great work Phil, thanks for posting these.

[cometcatcher]

These are amazing!

Thank you all for your generous comments I'll keep at Venus as I need the practice. My goal is to capture the dark surface details next year when the bright crescent is much smaller. To this aim I have made an occulting bar which I hope will allow me to get more hot surface detail than otherwise possible.
Cheers, Phil

[rustigsmed]

awesome Phil!
have you considered making a false colour or two with these? they are certainly good enough to...

[ags_]

I have thought about it but what colour is Venus? It's atmosphere is a complex mixture, although it is white to the human eye it would possibly be a pale yellowish grey. Any suggestions? an feel free to use mine for testing.

[rustigsmed]

thanks Phil,

here is just a pure RGB combine done in photoshop. the
B UV
G UV/IR 50% blend
R IR

think it looks fairly natural? comes out white with a bit of brown?

(edit second photo added with less extreme blue)

Venus IR & UV taken during the last 10 days with conditions very variable. I’m expecting the Jetstream will moderate and drift southward allowing the possibility for better quality images in the coming months. I am now 90% retired so more time will be available for planetary capture and processing, if this old brain can stand the pace.

Regards, Phil

The seeing improved the last 2 days which is a sign of things to come I hope

g day Phil,

congrats on the retirement and thanks again for posting your images.

i read that Akatsuki's infrared camera discovered an arc-shaped white cloud streak that stretched some 10,000 kms from nearly the south pole to nearly the north pole. it does not move with the atmosphere but sits above a highland region about the size of Africa that rises up to 5,ooo m from the average surface. i don't know it's longitude or even if its currently in view from earth.

looking at your IR images i see a brightening along the limb - i presume it is just that . . . or could it be the above feature?

regards, L

[ags_]

Thanks, I'm enjoying my relaxed life now I have no work pressure. The IR limb is indeed an artifact which is very difficult to hide and not worth the time involved compared to the UV which has much more detail and JAXA interest.

cheers, Phil

[Regulus]

Seriously good results Phil. Hard to believe I am looking at photos of Venus.
Excellent results

Another reasonable collection of Venus images despite variable conditions. There always seemed to be enough steady seeing between 5.00pm & 6.30pm, only on the afternoon of the 19th did heavy clouds preclude any image capturing.

Regards, Phil

[ags_]

The last 3 days

[ags_]

After 6pm seems to be the best time for most Venus captures

[ags_]

Lots of below average seeing for this set, and days of clouds recently so nothing after these.

[ags_]

Some reasonable seeing in this group

[ags_]

Excellent seeing on the 20th for these Venus images, the only thing behind the dense clouds was the sun.

[ags_]

A snapshot from the last 3 months and with an early cyclone up north the possibility that no more Venus captures this year

[Emc2]

What an interesting subject and fantastic photos.

[ags_]

very nice and certainly enhances the details. I have been trying to compare these with any colour Venus probe images and yours look much better!
