I first came across the term ‘Solargraphy’ on this forum and was directed to website dedicated to the art of Solargraphy.

This is a basic photographic method of recording the path of the Sun as the year progresses. This image commenced on 22 June 2019, the day after the Summer Solstice when the Sun was at its highest altitude in the noon day sky and finished on 22 December 2019, the Winter Solstice when the Sun is at its lowest point at noon. The silhouette of the neighbouring properties can also be made out in the picture.

Using a basic pinhole camera I was able to record every clear day the track of the Sun across the southern sky, each day  the Sun’s altitude was getting slightly lower.

Whilst the camera is basic, the main challenge is to avoid water damage and as you can see from the image some rain has managed to find its way inside. However, the pinhole camera is cheap to make with the following purchases made via Amazon;

100 cable ties £5.49

20 35mm plastic film canisters £8.88

100 sheets of Ilford Multigrade 4 glossy photographic paper £25.98

The remaining items were already in the house (drill bit, tinfoil, electrical and duct tape).

Given the potential for disaster I made two pinhole camera’s and one of them provided this image, the other was washed out due to rain water getting in. Making more than one camera certainly improves the chances of success. The camera's themselves were attached with cable ties to the down pipe of the guttering and facing South.

Anyone wishing to learn more about Solargraphy and how to construct the pinhole camera should check out Tarja Trygg's website http://www.solargraphy.com/index.php .

Excellent :)

I do want to have a go at this myself, assuming we ever see the Sun again...

Very nice end result, i am looking forward to those days when the Sun is a little higher clearing the conifers again.

Same here Peter, I live in a dip so at the moment the Sun hardly clears the trees or my neighbours house as you can see from the image.

      I am thinking of getting a Lunt 50mm scope. I want to image as well as observe. I am thinking I could put my ZWO on the scope and capture video. My question is, does focal length in a solar scope relate to the FoV as it does for a non-solar scope? The field of view calculator (http://www.12dstring.me.uk/fovcalc.php) suggests I could just about get a full disc with a focal length of 350mm (the 50mm Lunt), but not with a focal length of 500mm (the 60mm Lunt). Is my logic correct?

      So, I am going to take my first steps into observing and hopefully imaging the sun, and get myself a filter for the telescope, just so that I have something to do, when I am working nightshifts, or the weather is bad at night. From what I can see, all I would need is a filter like this one https://www.firstlightoptics.com/solar-filters/astrozap-baader-solar-filter.html. Is that so, or is there anything else that you would highly recommend that I get, and why? My telescope is a Skywatcher 150PDS on a Celestron AVX mount.
      On the same time, I am looking at buying a baader hydrogen alpha 3mm filter for imaging. Is this also something I could use for observing, or it is solely for imaging? Just curious.

      Any comments, tips, advice would be very much appreciated, as I would rather not damage either my eyes, or more importantly my equipment! (jk)

      Just caught up with The Sky at Night from Sunday 12th Aug.  Subject Coronal Mass Ejections from the Sun.
      Must admit I am slightly disappointed, if I am even allowed to criticise such a National Instution. ?
      First, the episode subtitle, "Death Star"      . . . Groan.
      Then the intro from Maggie A-P included the statement that  a CME's "could devastate our technological world . . "
      She said something similar at the end. IMHO neither statement was backed up by the rest of the episode.
      The boffins suggested some unquantified damage to power grids & satellites "which might have hardening or redundancies"
      So I was  left with the impression of some Millenium Bug style media hype. Would definitley be great aurorae though.
      What do you  think?
