A good effort Kon the jet stream turbulence was lousy last night.

Thanks Simon. I thought it might be ok as I images when it was quite high up. It's looking good tomorrow morning.

I knew the jetstream forecast was bad and it did not dissapoint 🤣.....Of the 10x2min OSC captures only a 2min file was worth processing. The IR did not fair any better but managed to derotate  2x4min images.

What has been said above are excellent suggestions. I have the 462 and I get 100fps at 10ms capture using a reduced ROI. Seeing has been horrendous and we currently have a horrible Jetstream above us so images are quite soft. Try get as many captures as you can and try derotating in winjupos. That way you pick the best frames.

Additionally, check your collimation on a star with your camera as this will make a huge difference between a soft and sharp image.

Under bad seeing, an IR pass filter will be your friend and can rescue a bad night. The 462 has excellent IR sensitivity.

Thanks Kostas, but where do I find these models, as I can't find them in either the windy app on my phone, or online at windy.com?

EDIT: Found it on the phone app...

Yes at the bottom. I use the online version.

@geoflewisand @bosun21 you can look at windy.com and see the direction of the wind at all altitudes in their wind models. Ideally all same way so not turbulent. Looking at tonight's forecast it's not good at least for my location.

Nice effort Geof and good to see you capturing the planets again. Dreadful conditions last night with that overhead jestream. I agree that the IR is showing the Seeliger effect better.

Nice images Oskari. Both images could benefit from a tiny bit of denoising.

Good catch Reggie.  The Seeliger effect is nicely showing too. We have been under constant cloud and rain so I missed opposition in the UK. I might get a break through the clouds later in the week.

Hasn't been delivered yet but it's on its way.

Was it you who ordered it?? Can you send it back as I haven't seen the night sky in ages 😂

I am taken aback by the generosity of @AltocumulusGeoff who sent me almost half a roll of Baader solar film for free (I just had to sort the postage). I have been looking for ages to make a full aperture solar filter for my 12" Dob but all UK and European suppliers are out of stock for the foreseeable future.

It's not the first time an SGL member that I have never met before has been so generous with me. What a fantastic community!!❤️

Let's hope the skies clear at some point to give it a try.

Hi Neil. What a great example this animation has of this effect. So thanks for posting this. When Kostas first picked up on this I thought I had a artifact through over processing the data. So well done to you both for pointing this effect out to me.

Bye the way It's great to see you posting again 👍

If you have more captures from the night it might be worth doing an animation and see if they move.

What is your definition of brighter and fainter planets/DSO? Observing DSO depends on the sky quality and experience in observing, so it is hard to say what you can really see or not. Additionally, binoculars (depends on their power) will show the fainter DSO and planets.

I would personally find such table more confusing and rather have the 'Which telescope shall I buy for my xyz circumstances?' question from new comers.

I knew you were near Oxford but not by how far. So it looks like our weather will be more or less the same the majority of the time. Do you know what causes the colour differences like both of our last images? It's puzzling as everything else being unchanged yet the colours when aligned and balanced is different. Must be the sky conditions surely. The go to on the dobs makes a big difference as you said. Thanks Kostas.

I touched the white balance to make it warmer but I think I made a mess of it. I will try go back to my normal processing. I think your new 585 has better colours than the 462 as it seems to bleed between the red and blue. I am contemplating on getting it but probably later in the year.

I am looking forward to your 585 captures.

You need to do a star test to verify collimation, looking at a terrestrial object will not give you an answer on collimation.

Almost identical to what I captured last week. Despite decent seeing my Jupiter was much the same colours as yours. Mars looking nice but small. December 7th Jupiter will be in opposition. Not looking good for Saturns opposition here in Oxford though.

I am down the road from you, outside Swindon, and the weather is looking as good as yours Ian 🥲. I am still to get a good Saturn this apparition but there is always hope (at least it is not silly hours to image it these days).

Both looking very good this early 

 

Thanks Neil. Quite frustrated with the seeing as I have not got a decent Saturn this apparition yet. The weather is not looking good for a while either.

Awesome image, Kostas. Great to see you out there again!

Reggie

Thanks Reggie. Back from summer holidays and I am glad I did as the rest of the week is looking awful with clouds and rain ☁️🌧️

Thanks Kostas,

However, I think the jury is out on whether I actually got the rings. I submitted my images to Mike Foulkes at the BAA and he in turn shared them with Martin Lewis. I had a few email exchanges with them both and whilst they thought mine was a good effort, neither of them were confinced that I got it, so I'll probably try again this year, if not overwhelmed with imaging Jupiter, Saturn and Mars.

I am thinking of trying Tom's combo of filters although Martin is keeping it simple.

It sounds like that you might be imaging soon? 🥳 

(I will message you later in the week)

Very nice Kostas. I have yet to have a serious effort on Uranus. I was out a few days ago and captured Saturn, Jupiter and Mars. Unfortunately the seeing was poor with a bit of interference from the Jetstream also. I had some nice detail on Mars coming through. I am hoping for a clear Jetstream free night this coming week to coincide with the opposition of Saturn. Fingers crossed 🤞.

Thanks Ian. Frustrating, especially when you stay up or get up early to do some imaging. It seems the best seeing was Friday morning but I was coming back from holidays and missed it.

That is impressive @Kon 👍🏻👍🏻👍🏻

Thanks Jeremy. It's nice when things work out.

Ahh that’s awesome I hadn't seen that post… must have been the sky conditions then that prevented me getting it with the Fullerscope, or maybe just not long enough exposure. IIRC I used 60x 1sec exposures with a L filter for the moons. Will have to try again with the 300p and see what’s what.  Never thought of going for the rings before, didn’t think it was possible tbh but I see there is a few images on Astrobin showing them 👍🏼

Have a look at this post from @geoflewis Geoff who seems to have got them last year:

Your 300P will be excellent to try.

Very nice capture, excellent work! Last time I tried Uranus was about 3 or 4 years ago I think with the 8.75” Fullerscope… didn’t get Miranda (at mag 16.1 I think it was) with it as just a bit too faint so glad to see the 300mm aperture can get it nicely. 

Thanks Craig. Actually, if you do a long capture with an IR pass filter you should be able to get Miranda with your setup; you will need to stretch the image a fair bit to see it. I managed it with my 8" manual Dob last year:

https://stargazerslounge.com/topic/416370-uranus-with-5-main-moons-251123/#comment-4435478

The 12" just needed a shorter capture to see it. I am optimising things to try for the rings this year.

Arrrrr.... ☠️🦜... sorry I had to. Very good to hear that it all went well. It sounds you might be good to go for planetary opposition.

Just noticed a slight blue cast on top of the globe while checking for any artifacts so tried to reduce it. I also increased saturation a touch more.

Hi Kostas I've had a good look but not sure what you mean.

The darker feature marked below. I think it is easier to confirm with an animation.

Very nicely done. A very difficult target!

Thanks. Very pleased with the result.
