Thanks for the view Robert and I am glad to hear there is some sunshine up there (my parents are on holiday not far away from you )


Alexandra

Very nice today too! R

Not much to image but sun!

Really nice images

Unlikely second day with sun and now two AR's, 25 minute animation (30 sec cadence), and GOES graph for capture time, C1 flare Robert LS60DS https://live.staticflickr.com/65535/33919710978_9da11c1c69_o.jpg 0507 07_May_19_103017_lapl4_ap517 by robertarnold , on Flickr https://live.staticflickr.com/65...

Really nice images. Sharp CaK and proms.
(Might need flipping vertically to be north up to match tiltsun?)

Very nice animation. Long time too. (Firecapture is good for sequences and connects to ssm.)

Lucky session just at the end of some C1.5 flares this morning.

Really excellent animation, caught the action!

Lovely!

Thanks for looking, clouds today but no storm. Wildfires nearby in the last couple of days

I use a Baader UV/IR filter for Ha and it definitely cuts out a slight foggy blur from far red light getting in the camera. When I first started CaK imaging with a Lunt B600 I used it and was very disappointed until I realised that it cuts out most of the CaK line! Only a very faint blurred image le...

Beautiful WL shots

Moderately good seeing today and lovely warm weather Robert LS60 DS https://live.staticflickr.com/65535/40732440863_ba256f3117_o.jpg 0425 25_Apr_19_120935_lapl4_ap525 by robertarnold , on Flickr https://live.staticflickr.com/65535/40732439723_8347d074af_o.jpg 0425 25_Apr_19_121636_lapl4_ap154 by rob...

Hi Alexandra Really interesting. I looked at your comparison images and aligned a part of Stuart's with yours. I think the y axis resolution is the same as Valery says but the x axis is smeared left to right by at least the minimum resolved image part. CaK test copy.jpg I have aligned a part roughly...

2. New Lunt / Coronado scope - we are talking circa £2.5K+ for a basic 60mm B1200 and nearly twice that for a DS model :o Plus these will have similar sweet spot issues as the PST (as I understand it). The positive here is I would be able to get a full disk image relatively easily with my ASI178MM....

very nice indeed!

Nice ani! It's always a bonus when the sun is out long enough to do one

It is, despite the changing haze which makes it difficult

very crisp, nice
Robert

Thanks Franco --- and added an animated scrappy prom shot 7 minutes long

Thanks Mark, ---- added an animation of 30 minutes

PST mod 150mm, hazy and poor seeing, but okish Robert https://live.staticflickr.com/7916/47534162752_5094cb3f5c_o.jpg 0411 11_Apr_19_102615_lapl4_ap473 by robertarnold , on Flickr and an animation of about 30 minutes (20Mb) http://www.robertarnold.co.uk/photographs/astro/Solar/animations/added/2019/...
