I use either the Svbony or Astromania (it came with a methane, UV and IR pass) IR pass filter; I have not personally seen any difference in quality between the two.

Spectacular! One of the best I have seen.

🙃 Thanks for telling me to get in touch with Paul, he is a great guy. I agree that @JokubasJarimages are excellent, I think some of the best I have seen with manual Dob on Venus. Since the discussion here, I found an old thread that you and Neil were discussing similar filters to what JokubasJar used on his imaging. We need more clear skies though!😆

Stuart, any feedback and discussion is always welcomed and not taking things face value is part of the fun. After all, most of us here are amateur astronomers and having healthy discussions and questions, can make us better in what we do and how we interpret our images. I am running a research lab so I am used to the questioning/criticism, and I hope I do not sound patronising. SGL is a great environment for this.

Thanks for the generous and kind offer on borrowing the camera (I will follow via message). Your UV images are outstanding! So much details. I remember Neil telling me that colour cameras are not very sensitive for UV imaging. Looking at the ASI site, the QE drops at around 40% at 400nm. I am not sure if you have seen the post from @JokubasJar who is having some nice IR and UV clouds (https://stargazerslounge.com/topic/406428-venus-irguv-feb-10th/) with a similar setup to mine. I will look into the filters he used for his UV imaging. The Astromania is giving a bad ghosting as expected for cheap filters; regarding gain i had 300 (50%) and exposure of 33ms so if up my gain it should give me a slightly faster fps. I also got a reply from Paul who stated (this is an extract from our email exchange): Your images of Venus do look very good! Usually the cloud markings on Venus are best seen in UV wavelengths, however a few amateurs have recording cloud markings in IR wavelengths this past few weeks, so it does seem likely that this is what you have recorded. I am a visual observer and I observed Venus yesterday evening with a W21 orange filter and I did notice cloud markings not to dissimilar from what you and others have recorded.

Stunning details. It's like flying over the moon.

Stuart @Space Cowboyand Craig @CraigT82 thanks for the further feedback and comments; Happy to be proven wrong if I indeed over interpreted the capture. I though the darker areas may have been the clouds in the original image. Based on Craig's images, I went back to my capture and pushed the wavelets a bit harder and I came with this more 'convincing' image? Thoughts on this one? I will also get in touch with Paul and see what he has to say and report back. Interesting as other reports I have read say that daylight is a killer for UV. I have a cheap Astromania UV filter but I found that I need to do 33ms exposures to get any signal though (I know the asi462 is not the most sensitive in that wavelength) and I only had 6000 frames to stack. I might look at the W#47 with IR cut as well.

You must be glad that you didn't change. The animation is awesome as well.

Stunning images!

Thanks. I was pleasantly surprised when I saw the stacked image.

Thanks Stuart. I am glad to have further verification. I hope to try with UV filter when the weather permits and try make a composite colour image.

Thanks Peter. Yes I was itching for an imaging session after the awful weather the past few weeks and the clear spell yesterday afternoon was worth it; I was also kin to try early afternoon imaging, as your mobile capture was superb during daytime. The UV signal did suffer imaging with the bright sun next to it; i can see something in the UV data but I think it is more noise than signal. By the time it was darker the clouds had covered my skies. Next time 😉.

Fantastic capture with the sun spots and ISS! A solar or lunar transit with ISS is high on my imaging wish-list but it always changes trajectory a day before.

I had a go at trying to capture some of Venus clouds with my IR and UV filter. I shot the images at daylight when the sun was up (1545 UTC) which I think compromised my UV results (not worth sharing. The IR pass is showing some nice darker structures (even in my unsharpened image) which are likely Venusian clouds. 8" Dob, manual, asi462mc, 2.5x TV powermate and IR pass filter. Resized 150%. (edited to add the more stretched image as well from further down)

Excellent result.

One of the best I have seen. It has a 3D depth to it. Excellent!

Good to see you back posting at SGL. Your valuable experience has greatly been missed.

Excellent report and the sketches brought your description to life. It's like looking down at the eyepiece.

That's a great capture. I wonder being higher up has helped with the quality as it usually boils at late afternoon.

Thanks Peter. Yes I was after the more natural appearance thus the request for some feedback. It's very easy to go on the wrong side of processing.

Thanks, I really appreciate your comment and feedback. I have a good baseline for the next capture.

Excellent report. You are spot on about the Flame and HH. That's my experience when i saw it, as I used the Flame as my first clue on seeing quality. Regarding Barnards Loop , I have never tried it. M78 is easily visible on my 24mm EP and I should give the Barnards Loop a try next time. Would you say the UHC or Hb are better to see it? The hot tub sounds amazing too!

That's an excellent image and some really nice clouds are showing. The W47+IR block filters have worked really nicely. Which ones are you using please?

Welcome back Gerry. Great observing report.

Excellent mineral moon. Nice details at the edges too
