Large prominence on the sun

[Roel]

Today I made the first sketch through my new 70mm modded PST. The scope showed a lot of detail, but a large prominence on the northwest limb was the most stunning feature. It was large, wide, and it changed shape within minutes. I made two sketches, one at 12.00UT and one 20 minutes later, at 12.20UT. The prom clearly changed shape an structure a bit and the base was much wider. It looked as if the prominence was falling back to the sun!

I sketched with graphite pencil on white paper, inverted the sketch and pulled all the levels to "red" () with Photoshop.

I can say I'm VERY happy with my new telescope!

You should be very happy with those sketches too, they're really beautiful!

[Ursa Major]

Very good. I thought they were images at first.

I'm looking for a new scope , after seeing these sketches a solar scope could be on the cards!

Superb, really like it..

I thought they were photos also!

Great artwork, and obviously, very fast drawing!

Congrats!

Two excellent sketches, well done.

It's just a shame that using a laptop is infinitely easier than learning to draw at that level - otherwise I'm sure we'd all be trying it.

Very nice sketch. It's good to have a record of how the sun changes over even just a short period of time. Nifty processing with the colour change too. Well done.

Congratulations on getting this sketch on Astronomy sketch of the day today.

That's wonderful that is. And I love the concept of post-processing pencil sketches too. Look forward to seeing more!

really beautiful Roel. Thank so much for sharing.

I'm having a look at your site too and the recent HA sketches are stunning.
