Very nice Stuart. Quite a dramatic change from two days ago.

Cheers Kostas!

As Forrest Gump once said "Venus is like a box of chocolates, you never know what you're gonna get" 😉

These are wonderful - it's great tracking the phase changes via images posted in this forum!

Thanks! I've been surprised by how much Venus has had to offer. I'd never bothered before with UV.

Yes, I wondered if the limbs were going to be burnt out after sharpening! 

The crescent is developing fast now. We've been so lucky to have the good conditions when there was still plenty of surface area.

Not as good last night but quite a striking new look for Venus.

At least with Venus even if seeing is less good you still get a different look.

A Brazil nut came to mind when I first saw the live view last night. 🙂

Really fine images again, good to see you have sorted the artefact out on the colour image.

Thanks again Pete. I was going to try video derotation to fix the field rotation but it appears that winjupos does not have video derotation  for Venus.

Thanks Pete! It's nice to have such good conditions to try out a new camera.

Thanks Stuart. These took really long to process as I felt I could pull quite a bit of details out. I want to have another go at them. I hope you are out tonight as it was looking excellent earlier on.

Look forward to seeing your latest shots! I had to miss last night but will be trying for rest of week.

Fabulous images Stuart,  the conditions were very stable over the weekend UK wide it seems. Some really fine details visible in your images, excellent end results !

Thanks Pete! Best sustained conditions I've ever experienced. Looks like weather is breaking at weekend so I'll be trying every night until then 🙂

Superb Stuart.  you guys are just slaying Venus in the UK. Congrats on the amazing results. Stunning comes to mind

Cheers Neil! You've always been the inspiration. Encouraging me to try Venus and get a UV filter. 🙂

I've edited the post replacing the false colour image with a colour balanced version.

Fabulous images Kostas! Love your colour balance, nice and clean!

Cheers Kostas! Look forward to seeing yours. This is what we dream about!

The great conditions continue!

Quick process from last night.

10" Dob with QHY462 mono & bessel U for UV. QHY585c for OSC.

19.34 UT.

35 degrees elev.

False colour:

I've done a quick clone touch up on the artifact line. Only took a few secs. It seems if there is a gap over 40 mins between UV and OSC shots the winjupos produces a seam I'm assuming caused by field rotation.

Thanks Kostas & Neil! I've put up the colour image. As you can see no line on that either.  Also tweaked the colour balance on false colour to take off the blue. Not easy when its in daylight.

Yep, conditions are what you dream about at the moment. Make hay while the sun shines as they say!

Ok,  I know whats causing the line. Too much time between UV and colour images in winjupos. . One hour. Tried a later UV and theres no line.

Super seeing again last night. Super QHY462 mono cam too!

The artifact on the false colour image is doing my nut! Its not ana alignment point line. I've tried different images combined and its still there. Seems to be something winjupos derot of rgb is doing but why I don't know!

Happens a lot here actually. Maybe a coastal thing. 

Never known it clear and stable for such a long period here.

Hopefully your technical issues don't crop up when things get serious but I can still imagine the frustration at that time in the morning 🙂

Lol i wish she blew a bit harder. So she wasn't playing cloud hide and seek 🤣 Hope to get a reasonable one by the time jupiter is up. That's not long trailing behind. 

Crystal clear here in the west. Seems the east end boys are getting some of the fluffy stuff 😎

Thar she blows! 💪

That looks very nice. Gives you a bit more elbow room with processing if there's less noise to deal with. 

I would imagine it would make focusing easier with less noise on screen?

Good point on derotation; I will investigate. Saying that, wouldn't PIPP stabilisation deal with that? I always put my captures through PIPP with quality prefiltering.

I've not heard of Pipp fixing field rotation. I did try it on a solar sequence a few weeks ago and it had no effect on the field rotation. At 50 degrees you're getting a fair bit of field rotation. The better data might show some benefit from derotation.

Thanks Stuart. Yes very chuffed with the ZWO selection. It gives me confidence on my processing but that image I submitted was under the best conditions I had so far with Venus. 

I am looking froward to seeing more images from your mono captures.

There's a lot of skill involved in your imaging before you've even started processing that's for sure.

I was thinking, considering you are shooting earlier in the day at 50+ degrees have you considered video derotation for the field rotation?

Plenty of detail none the less. Congratulations on your ZWO award Kostas 👏

Been very busy here all week hopefully get another crack at Venus this weekend.

Those are just lovely. Right up my street. Not overcooked, Natural subtle, but very fine wispy cloud. Hey wanna trade locations ill throw in a laser

LASER CANNON

Thanks Neil. Basically I used the same wavelets as I would on Jupiter or Mars. Fine gaussian rather than the sledgehammer dyadic. 

I was having to use a Laser cannon on the noise with the old cam lol

A couple more from the smaller sampled runs. Minimal processing, just a touch of contrast after registax.

I must give Bernard at Modern Astronomy a special thanks for the QHY462 mono.
