Hi, I am using a gain of 279 for some ordinary limb+proms exposures, this seemed to give relatively low noise but an obvious increase in the luminance of the background proms area (which I can control using luminosity masks and levels/curves adjustment) fairly easily. Magnus Beware ;-) The dominant...

Thanks Alexandra!

It was a lucky capture. I had not heard of this sunspot until after I had captured it.

Thanks Dennis,

I did not realise the Apollo M-Max was IMX 432 with 9 micron pixels.

Hi Solarchat, I was trying out my 120mm SW achromat and my Quark did not power up due to a faulty cable connection. I imaged the new emerging sunspot AR3633 (visible from Mars!, as on spaceweather.com). I should have added the earth for comparison. Effective focal length 4200mm. Magnus 10_50_01_lapl...

Hi Alexandra,

Thanks so much for the Acuter Merlin. I checked with some retailers and this mount is no longer on sale, so I shall either go second hand or look for the equivalent. Probably one of the newer AZ mounts.

Really nice setup and incredible solar images Alexandra.

I wouldn't expect significant image quality differences between same-chipped cameras from different manufacturers. Though there might be some regarding how USB I/O is implemented, etc. For instance, when I'm recording with my FLIR (formerly Point Grey) Blackfly S to an external SSD, I can simultane...

Hi All, I have read varying opinions on the camera most suitable for solar imaging. I have a ZWO ASI174mm which is fine for discs, part discs. When imaging proms I noticed a lot of extra noise and luminance in the background, so the proms are sometimes hard to make out clearly in the background bri...

Hi Pedro,
Is that a holder for front D-ERF for a h-alpha filter or tri-band filter ?

Many thanks.

Magnus

Radon86

Good point. I need to make my diy solar scintillation monitor. I have most of the parts. My seeing is probably average to below average but I need to measure it.

Magnus

Radon86

Hi,
No problems imaging proms, just getting the quality that Carbon60 is getting. And low noise and high contrast views of the ptoms.
I will work on my 90mm and 120mm refractors for the time being.

Radon86

Hi Dennis, Mainly Quark chromosphere eyepiece with a 70mm F6 refractor. I also have a 90mm F10 refractor and 120mm F8.33 refractor. I have 2 inch ERF (uv-ir cut filter or 35nm H-alpha filter). Camera: ASI 174mm I get about 6 to 10 ms exposures for the limb. If I expose for proms only it gets noisier...

Radon86

Hi Stu, Very detailed and low noise animation. May I know what h-alpha filter you used and the ERF (as I do not remember your equipment list). I have a 120mm achromat (F8.33) refractor, plus a Quark Chromosphere. Would that be useful to image the proms like you ? I think I should probably use a fron...

Radon86

Hi Dennis,

So I need to focal reduce or using a front mounted h-alpha filter ??

Thanks.

Magnus

Radon86

Hi,

I think I have got tuning of my Quark chromosphere eyepiece for disc details - usually at +2 setting on the quark dial.
I was wondering about imaging only the PROMs.

Is the setting different for this - dial setting is turned to what setting exactly ?

Many thanks for any advice on this.

Magnus

Radon86

Hi Alexandra,
I was wondering if I could find out how you laid out the various phases of the eclipse in a spiral?
Is that a path in photoshop?

I haven’t been able to work it out.
What mount did you use to track the sun.

Thanks.
Magnus

Radon86

Hi Amit, Very detailed and helpful outline. I was wondering about tracker mounts as that would reduce the need to adjust your camera position as the sun moved across the sky. Any recommendations? And what are you taking. Then there are battery and power supply. Should there be a special image exposu...

Thanks Dennis.

Hello Dave,

Why is the sun so big ?
Can you give me a link to your cardboard PST, I am intrigued, I have never heard or seen cardboard being used.

Many thanks.

Hi, Does anyone know or has used an Atik 314L+ mono for solar H-alpha imaging ? It has 6.46 micron pixels, is a cooled camera. I do not know its FPS for getting videos, but it does work with SharpCap. Any advice and info would be appreciated. I would be using it with a short focus refractor at 420mm...

Hi Brian,

Very good imaging and processing - super FDs!
How did you get this full disc ? Did you use multiple panes and photo merged all the different panes or was it a single video/frame ?

Many thanks.

Hi Mark,

How many frames per second are you getting - a range of low to maximum attainable (depends on image size) do you get ?

Many thanks.
I have a 1 TB SSD (NVMe) on an old HP laptop and 16 GB RAM and it gets about 64 fps on a normal image size of a ASI 174mm I think in SharpCap.

Today the only task was to test the new Quark combo chromosphere. The weather is terrible. Just a few pictures for the whole day. AR150/F6, TV4x, Quark, IMX432 Hi Pupak, Is this the Apollo M-Max or equivalent ? What about your refractor, is it an apochromatic refractor costing 7000 USD ? Fantastic ...

Hi Kevin,

How did you find the comet ? Did you use EQMod and Stellarium ?

Thanks.

Hi Warren,

Lovely capture !
I did not know there was a Canon 7D mark3. I bought the original Canon 7D in 2008 or 2009. I still have it although the original got damaged.

Magnus

Radon86

Hi,
Why are there so many stars ! Amazing capture

Magnus

Radon86

Hi Kevin,

Wow ! Amazing. I think I will try my Canon 6D. It is an excellent camera, just a little heavy.

Any chance of showing us a single exposure before any processing ?

Why ? Because it would help me decide what is a good exposure.

Hi,

Where did you find these weather maps, that is exactly what I was looking at.
I am not so advanced on my eclipse research so far.

Looks like we are probably too late to book hotels.
Can we just sleep in the car or pitch a tent somewhere ?

Thanks guys for your compliments. I think the “seeing conditions” were very good. Normally the sun is moving or hazy at these times.
Pity I could not stay for longer at the scope.
