#Jupiter, reprocess - definitely my best to date!

Today's Sun in Hydrogen-Alpha wavelength. Skywatcher Heliostar 76Ha scope & Player One Apollo Max M camera. Close up of sunspots 4 panel mosaic (x4 barlow) AR 4409, 4408, 4406, 4404

Some solar work this afternoon. shot through high level clouds/mist

@BeatriceHeinze I recently purchased Affinity too as my PS was a very old version (CS2) but still does the job 😂. I’m also looking into LuckyStackWorker atm which could remove the use of Registax, winjupos and PS. Again it’s free!

@WilloTC @Celestron @TeleVueOptics Thanks for your response! I know them all but instead of Photoshop, I've Affinity Photo as an alternative.

#Jupier from yesterday evening (18 March 26 - 1940hrs UTC). Oval BA just leaving the disc on the right of the disc (4 o'clock position) @Celestron C11 telescope and Player One Uranus C camera & @TeleVueOptics x2.5 Powermate

@BeatriceHeinze @Celestron @TeleVueOptics Thanks Beatrice. Software used was: Autostakkert 4 for stacking. Registax 6 for wavelets and winjupos to derotate the 10 images. Final tweaks in photoshop. Other than PS all free software!

@WilloTC @Celestron @TeleVueOptics Beautiful astrophoto! What planetary processing software did you use for this image of Jupiter?

Very quick process of #jupiter taken this evening 18 March 2140hrs.

@KevinAstrokev So we are saying f18 😂. It’s a good comparison but with poor conditions it’s difficult to judge. But agree 27 over sampled by lots.

@WilloTC x.com/i/status/20332… Paul - my results from testing barlow focal ratios, which may be of interest

On the seeing index....current conditions are about "why did I even bother" 🤣 high jet stream above the UK = terrible conditions

@KevinAstrokev That said the powermate series are designed to remain around the same magnification regardless of sensors distance 🤷

@KevinAstrokev Have you got a link to any calculators for it? Looks like I’m having a busy Sunday 😂

@KevinAstrokev Just let me have the solution when you found it 😂😂😂 I always struggle with the tech aspects. More of a fake it till you make it guy 😂. Now I’m at the point of nearly there it might be time to read the manual though 😂

@WilloTC /2 I took images last night with this arrangement and with different spacers also. Image size has reduced, which is good, but need to measure them to confirm what f-ratio i was getting. Also, need to process fully to see if it's improved the image or not. Better seeing would help

@novafred Yep and like all kids it just won’t leave home 😂

@WilloTC The Jetstream was born over the UK!

@KevinAstrokev You’ll only be able to get it’s true value in good seeing conditions through. In theory you should be using a 1.5 Barlow..I tried with the Uranus c and didn’t think it was good hence the switch to 2.5.

@WilloTC Haha fair enough! Im just curious to see if it makes a worthwhile difference. We will see!

@0xoty I should have set up for DSO last night as I knew the seeing was going to be bad …but I’m a fool for thinking the weather forecasts may be out 😂

@WilloTC This happens every time I swear in the uk, I always think, great some clear skies and then look through the eyepiece 😭

@KevinAstrokev I’ve never tried to work it out and I’ve got the ADC after the Barlow too 😂 point and shoot that’s how I fluke this hobby 😂

@WilloTC D'you know what f-ratio you're operating at? Ive learned that it varies depending on separation between barlow lens and sensor. My "x2" barlow was increasing my f/10 scope to f/26 (not f/20 as I expected). F/26 is too much for my camera. Optimum f-ratio is 5-7x camera pixel size

@KevinAstrokev I’m using a x2.5 power mate which seems to pair well.

@WilloTC Yup. Im out testing different barlow configurations, but seeing isn't great

For those who like telescope building or fiddling with optics, here is a new webpage on SkyInspector.co.uk about chosing the right black paint to reduce spurious reflections from the sidewalls of optical components skyinspector.co.uk/matt-black-pai… Let me know if it is useful to you.

That should be AR 4392
