Hi Robert!
Super looking solarcan image! It looks just as good as the ones they put on the instruction leaflet on the solarcan.

Can I practice processing on your image you have posted ? Thanks.

Magnus

Hi Stuart ! I love your solarcan result ! Can you explain the original scan please ? Are the dark lines across the sky the solar images ? And the white foreground the landscape etc ? It looks like you missed the highest parts of the path of the sun in the summer - what do you think you could have do...

Radon86

Thanks Mark! Wow I never realised this would be so complicated! I found this from a CloudyNights post: https://www.cloudynights.com/topic/744934-baader-variable-iris-screen/ [and the variable iris stop in teleskop-express] https://www.teleskop-express.de/shop/product_info.php/language/en/info/p7797_...

Hi Michael, Thats a very interesting website, I had not come across that before!! Reading the annular eclipse report - that is very long, I will go into that later. I am not sure if it would be worthwhile to go to a annular eclipse as you have to view it always with eclipse filters and can never tak...

Hi, Maybe your machine is overpowered ? A lot of RAM and i7 as well ! Check what your buffer size is ...that can be changed according to your hard drive space, so you can perhaps maximise or increase your fps. I do not think fps more than 100 is necessary unless you are working on impossible (for su...

Radon86

Thank you guys for all your valuable advices, you are all really helpful For Christian: I checked that the maximum fps at full sensor size in luminance mode (firecapture setting) is 33-34 fps. It gets up to max 50 with red filter setting (I don't know why firecapture does that, but that is also the...

Fantastic :hamster: :hamster: :bow yes I would like to see a blue patch appear one weekend / day off too, this mysterious hot thing only shows itself on work days ;) Alexandra Hi Alexandra, You are very lucky to have so much time at weekends to image !

Hi Luca, I thought the Daystar Quark combo was designed for F15 telescopes ! Here is a link... https://www.firstlightoptics.com/daystar-quark-solar-eyepieces/daystar-quark-combo-h-alpha-eyepiece-chromosphere-prominence.html Do you find the x3 barlow/telecentric gives good results ?

Excellent idea ! Verifying Einstein's general theory of relativity again !
I have to read 21 pages of the article, excellent reference to work on to verify the bending of space time !!!

Jordan,
I could not access your image you indexed in your original post. Do you want to show us what you are working on/having problems with ? Maybe one of us can show you the steps towards the goal you are aiming for.

Good imaging and may I wish you the Season's Greetings!

An incredible miracle happened this week over my garden in north of France: during a couple of hours on 16/12 the sky suddenly turned into blue and some round thing incredibly bright and hot appeared flying on it! I took a picture because otherwise people will never believe me... (APO 102 f/5 diaph...

Hello Derek, So you are using a 40mm Lunt solar telescope and adding another 40mm etalon to it at the top ? Why is the inner etalon look different to the outer etalon ? Do you need to buy 2 LS40 lunt solar scopes to get to this double stack arrangement ? Any chance of sample images from your wonderf...

Radon86

Superb work there Clare and Peter !
I am somewhat jealous of your double stack setup!!

Hi All, Has anyone encountered the "flashing line or lightning" appearance of the live image view of Firecapture 2.7 (latest version). It looks like lightning ! Here is one example, not all of them look like this. Does anyone know the cause ? It does not seem to happen in SharpCap usually....

Hi All, Recently I discovered that whilst imaging for a Full disc using focal reducers with a Quark, in Firecapture: the aperture stop can cause problems when making flat frames when applied to the imaging. My eureka moment was: When applying the flat frame, movement of the dewshield (if it moves an...

Excellent capture Warren and thanks for sharing which really shows everything too.. By the way, even 4-Terrbyte External HDD's up to 16Tb-SSD]s are now available and reasonably priced ?? Terry Hi Terry ! I actually ordered a 6 TB SSD (low price from Aliexpress this year). It turned out to be 8 TB !...

Radon86

Stunning ! That double stack really works !

Magnus

Radon86

Thanks Maurits and Warren. and Starhugger,

I hope to process all the images of the proms (which was high gain and only that of the proms) later this week hopefully, and see if an animation of that massive tower prom comes out !

Magnus

Radon86

Thanks Alexandra, I tried to reply earlier but there was an error and I could not send the post. I will try and do research on the sites and weather prospects/historical weather for the most suitable sites for total eclipse. Probably not Niagara Falls though ! I got an email from eclipse holidays (c...

Hi All ! After weeks ? of cloud and grey and rain, the sun appeared with less humid air and little wind ! I set up my 70mm refractor with the aim of trying some quick eyepiece photographer with a phone camera. I wasted alot of time and could not focus at all throught the 40mm eyepiece. Anyhow, the w...

Thanks guys for your appreciative comments. I hope you find some clear dark skies and get the chance to gaze at amazement at the Milky Way, a truly awe inspiring sight if you have never seen it before !

Magnus

Radon86

Hello Warren! I notice you take a lot of solar images, including Full discs. May I ask how you keep the file storage manageable? Do you delete your video files after a set period, say immediately after you processed the video and are happy with it, or do you store them ? for how long 1 year ? 2 year...

Radon86

Hi Alexandra,

Yes, it is a composite/blended two separate images. The milky was is a stack of about 9 files to create increased signal/noise image.

I'll try and drink coffee next time at a dark sky site and see if I can photograph it directly !

Magnus

Radon86

Nice work and disk, Peter !

So many proms, I have never seen so many, incredible !!!

Magnus

Radon86

Hi All,

Just an idea I had with all the bad weather. Having coffee under a dark sky. Here is a part of the Milky Way core I took in May 2018 in Mount Bromo area, Indonesia. Combine that with a coffee mug...

Hope you like it.

Hi Jochen,

What camera and lens? Was it all hand held or on a monopod or tripod?
Did you special noise software eg Topaz denoise AI or DXO Raw Prime …?

Super photos!

Magnus

Thanks Pedro.

Magnus

Super news Valery!
I hope the Russian soldiers and missiles disappear into a black hole !!

Excellent again H-alpha.

Someone tell NASA they are wasting money sending probes and satellites to Mars. Just outsource all the work to this man !

Magnus

Radon86

No I did not know about this service actually.

Hi,

Is there a case to start a separate forum section to discuss/prepare for the next major total solar eclipse?

I was hoping for solutions to take automated solar images during totality and pre and post totality via computer.

Would Alexandra/Stephen/Mark be able to consider this please ?

Magnus

Radon86

Hello Peter, Thanks for your brilliant post and animation. I should add that I tend not to setup my solar when it is too hot as it can be too difficult to concentrate in very hot weather and I do not have solutions to protect equipment apart from a cardboard shade on the telescope tube.

Hi All, Any one planning to go the USA for the total eclipse in ? April or is it March 2024 ?? Did any of you guys go to the eclipse in 2017 apart from Alexandra ? Did you go on a tour or did you book your own, going to less expensive bed and breakfasts for accommodation ? I suppose there should be ...

Hi Rainer, Apologies if I did not understand your device. Has it achieved 35 celsius or 35 Kelvin below the ambient air temperature? Is this the sensor temperature? How to use this when the ambient temp is 10 degrees, then your sensor will be minus 25 celsius. Will that cause cold damage and sensor ...

Radon86

I was missing the very important step of aligning the camera sensor with mount movements, it's so much easier now thank you! I found out from a solar imager on stargazerslounge.co.uk that : 1) autostitch64 can be very effective 2) alternatively - Microsoft ICE 3) Photoshop has a photomerge function...

Beautiful sunny day, 17F/-8.3C but I set up anyway, got a full disk, tried an animation but the seeing was really rough and my BF heater just could not keep up with these temps.

Very nice photos Alexandra.

Looks like you have quite a dark sky there ! Wow, you are very lucky in Cheshire !

Did you try a high dynamic range image of your landscapes/sunsets ? Or you can do luminosity masking and adjust levels and curves for the sky and background independently.

Magnus

I was missing the very important step of aligning the camera sensor with mount movements, it's so much easier now thank you! I was pondering the solar mosaic problem as well.

It appears you did a good job here with your discs, very good Jochen !

Radon86

Christian has been explaining that a narrowband O3 filter is better than a 540nm continuum filter.
Maybe going up in altitude will result in better detail as well. Still, thank you Baader, another 170 gbp sterling going your way!!

Radon86

Veru interesting. I never tried ASZiCAP before.
I think Firecapture may have guiding functionality, and GreatAttractor (Filip) did use specialised solar tracking software for his prom animations recently.

Radon86

I think I could have imaged this with my Quark and 70mm refractor if the conditions were right.
How low is the sun where you are Warren?

Magnus

Super animation there Warren!

Hello Andreas, So you are imaging at F7 on your Lunt100. Is it a double stack version, Andreas ? I also thought that the optimal sampling ratio for the QHYIII-174M was F21.6 approx (see Wilmslow Astro)- https://www.wilmslowastro.com/software/formulae.htm#CCD_Sampling [imaging in H-alpha at 656 nm] W...
