Here's Venus from last night 5/3/2020. Seeing was pretty good. This was shot on a Celestron C5 with Televue Powermate 2.5x and ZWO ASI224MC camera. No special filters.

Another Venus shot through some sucker holes last night, the crescent is getting smaller (thinner and longer)...  Still waiting on my new filters, very minimal processing.

Captured just over an hour ago. (Took the liberty of adding background stars from a previous shot)

I ordered a Baader UV filter with the intention of getting Venus when it's in the early morning soon, closer to a 50% phase, so with better seeing available. Tested it last night with a Orion 127mm Maksutov, which seemed less impacted by the atmosphere conditions than an 8". It was taken with a ZWO ASI 224MC camera.

I can honestly say, I have never been that interested in observing Venus...  In my opinion, not nearly as exciting or breath taking as the moons and rings of the gas giants, or have the incredible details available on the Moon.  Once you see the crescent of Venus, you've just about seen everything.  I did not realize how wrong I have been...  In this thread, I have presented my first modest image of Venus while not an exceptional image I have been able to image Venus 3 times over the last 2 weeks and the change in the size is very interesting, making me regret that I have not started this little "project" much earlier in the year.  These images all have been aquired using my Intes MK-67 f/12, ZWO ASI224MC, FireCapture 2.6, and AutoStakkert!3, all taken with the same conditions.  I have published the diameters from the Autostakkert!3 text file, while I do not know how exactly it is calculated, they seem to reflect the data.  I am positive, I never would have noticed the subtle changes in Venus' size and shape if I would not have imaged.

I took one capture tonight with my Celestron C-6 and ZWO 178MM camera mounted on a Great Polaris DX mount. Venus was just starting to get in the tree limbs (and below 30 degrees) when I decided to cut the capture short. It's all I had time for. The seeing was average at best. Considering that, I thought it came out okay. 

 

Processed in Autostakkert, Registax, and Lightroom. Thanks for looking!

Venus at just after 8PM PDT on May 14, 2020. Taken with a Celestron C6, A-P Advanced Convertible Barlow at about 1.8X, ZWO Atmospheric Dispersion Corrector (ADC), and a QHY5III-178C camera.

 

The crescent is getting pretty thin, at about 14% illumination with a diameter of 48.6 arc seconds according to SkySafari. This is a color image and the ADC handled the color dispersion very well (best 10% of 6000 frames). The "rainbow" version was without the ADC (although if you use AutoStakkert!'s RGB align feature most of the color dispersion will be removed).

 

Image capture via SharpCap with processing in AutoStakkert!, PixInsight, and Photoshop CC2019.

Nice shots,  james7ca. 

 

I particularly like the comparison pics with and without ADC.

Question:  have you considered shooting Venus in daylight, when she is culminating?  At your location, she may be very near the zenith, and perhaps the ADC would not be needed?

 

regards,  kbl

Yes, I've shot Venus, Mercury, Jupiter, and Saturn during daylight using IR-pass filters.  Also some stars down to the 6th magnitude.

During these pandemic times I managed to capture Venus from my balcony using my 127 Mak and a modified webcam. Click on image then Download original... for original resolution.

Here are a couple of pics I took this morning with my AT80ED refractor and my ASI290MM camera using a UVenus filter. Captured with Firecapture, processed with Autostakkert!2, Registax wavelets and a little color in GIMP.

I had exceptional skies this morning! After I imaged Comet Neowise and the Moon, I made a few exposures of Venus, roughly 1000 frames each, taking the best 20% of 1000. I used my AT60ED refractor, 3X Barlow (F/21), ASI290MM camera and the Baader CaK double stack filter. It really showed some faint details in the clouds of Venus.

 

I used Firecapture 2.6, Autostakkert!2 and Registax wavelets.

Here is my latest pic of Venus, using my ST120 achro refractor, 5X barlow, ASI290MM camera and Firecapture 2.6. Post processing with Autostakkert!3 and Registax wavelets.

 

I added an IR 642nm band pass filter to see if I could get some upper cloud features, but I don't see any.

Me also tried to use a #47 violet filter to see some details, but I think I'm limited by 3 things: camera, aperture and distance to Venus at this moment. I can also add the bad seeing and strong wind. Maybe when aparent diameter will grow I'll take better pics.

Watermarked pic - no filter

The other - with #47 filter

Hey guys,

 

there are my results from yeasterday around 13:00 UT time under decent conditions. Windy, but overall decent seeing.

 

Taken with my 3" ED72/420 + 2.25x Barlow and ASI120MC-s + EOS600D (for comparison).
