My first love (C11 30th May)
This morning I was out and set up early by 08:15 BST and went back to my first love...
Could I replicate last years white light at 5x Powermate, oh yes I could. I had 30 minutes of pure heaven watching the video feed. Like normal they don't quite stack like the video but this for me is pure delight. I could do WL forever

I then bypassed CaK (still nothing from Televue apart from "we are working on it" so went to the PST mod. Seeing was immediately worse and these were taken with a 2x Barlow. Still happy though but not the detail Valery or Alfred get. But I certainly can't get that level of fluffiness with the PST or the Solarscope

Sun_073742_30_05_2020 by Alexandra Hart, on Flickr
Gave up and moved onto the Solarscope at 9.30am but seeing wouldn't even support 1.6x by then at 100mm
I seemed to be learning my new seeing. Pre housing development I would have beautiful seeing from 8-11am. Now it seems I have good seeing between 8-9 only, then very bad, then it gets betterish as it comes over trees at mid day. So basically I need to image between May-July and try and squeeze everything around maybe 7:45 (if I can get up quicker) to 9am. Pity I have lost my field

Re: My first love (C11 30th May)
Impressive granulation details, Alexandra, H alpha is good too considering the seeing.
My best hours for imaging is from sunrise to 10:00 am in spring and autumn, summer and winter are worst seasons for solar.

Re: My first love (C11 30th May)
These are amazing! Huge leaps forward. Both the WL and Ha are lush. What blocking filter are you using with the PST mod? The single stack or double stack from solarscope - which ever gets the most light through is the one to use, keep exposure short. I knew the seeing was being the badly behaved creature in all of this for you, but you have your window now and know when it is. Urbanisation is not our friend in solar.
The boss is putting in official garden ornamentation around my new 'pad' today, and I will move my scope later on this afternoon. I should gain an hours extra good seeing from it, my seeing goes to plop around 9am where the scope is now.
Really really pleased for you!

Re: My first love (C11 30th May)
Thanks guys, I really do love the Sun when this happens, it is like a drug rush
Mark, I always use the single stack blocking filter with the PST mod, I know this is darker but I feel the band is slightly better, maybe I am wrong and should do a comparison. I just feel I like it better.
I need a good spot on the Sun now

Comparison is probably worth a go. I trust this afternoon will be a celebratory wine or 2 in the sunshine?

Re: My first love (C11 30th May)
Those all came out quite nicely, Alexandra.
Looking forward to what the HA will look like when/if you manage to catch some decent seeing.

Hi Alexandra,
Those WL images are sublime! Mine end up too granular/bead-like. You’ve inspired me to try WL imaging tomorrow morning to see if I can get anywhere close to yours.
Just a couple of prom shots from me today, which I’ll post later.

Re: My first love (C11 30th May)
I love some good white light granulation. Something weirdly satisfying about a clean disk. I got so wrapped up in Ca-K this morning I forgot to do white light.

Alexandra,
All are great but the granulation is utterly impressive! Incredible resolution. The spicule fur shows well too. The sun looks as furry as a cat. Was you at full aperture or stopped down a bit?

Your images are refreshing and inspiring, especially the WL images. Thanks! I will go onto the WL and G-band after experimenting with extenders and Powermate x2.5 in CAK!!
My initial images using the C11 H-A with PST mod are similar to what you have now. I look forward to seeing more HA images.
BTW, did you use flats for the HA image?
A quick update: I was able to reduce the effect of the brightened area in CAK using Powermate x2.5. However the image quality was also degraded. I am still in the midst of tinkering. Will post some images later.

Re: My first love (C11 30th May)
Wow, great images, in spite of the trials of urbanization! Every time I see images done with c8's or c11's I get the urge to pull the trigger on an aries ERF. So far I've resisted since I also like to eat, but one of these days, lol.
Great processing too, I'm still learning on this front. Some of my images seem to take very well to colorization, and others seem to reject every effort, in spite of very similar acquisition and processing. Haven't nailed down the reason why yet, but there's always more to learn!

Re: My first love (C11 30th May)
Thanks everyone for all the kind words
Mark, celebratory G&T in the side garden in the shade watching my fussy sparrow check out their new residences (we keep moving them as they never seem perfect enough for the fussy women).
James, these were both at full aperture.
Alfred, yes I did use a flat and I chopped off the right hand side of the image which was off band as recommended by others.
Ammonthenephite, honestly, you don't need to eat just drink! well, I give the hubby plenty to drink and then slip in a comment on what I really probably could do with next

Re: My first love (C11 30th May)
Hi Alexandra, those two "porridge" images are quite fantastic and the other images are really great too - very well done...
If I could fit a C11 into the observatory, I would, but even though some years ago I had the opportunity of getting a similar scope, it would mean that the observatory-roof would neither open or close - without having to remove it from the pier - every time...
The Tri-scope assembly doesn't suffer with that problem as long as I park-it properly and watch for any changes to the camera-attachments !!
Best Wishes for more fab images from you
Regards
Terry

Re: My first love (C11 30th May)
Incredible, WL images, Alexandra!
That is an amazing image and your setup must be incredibly high resolution!
About your H-alpha and Ca-K images, and your "poor seeing".
I also live in the suburbs, and maybe your seeing is getting to what I experience in the suburbs in London ! I did not think it would such a hindrance, I thought it was more due to the jetstream and upper atmospheric effects.
Ground and near ground effects I did not realise was so serious. Am I right ?
Do solar imagers have to move or something to a better observing site ?? or restrict imaging to certain times of the day and year ??
Many thanks.

Re: My first love (C11 30th May)
Thanks guys!
Franco, I made 2000 frame ser videos and stacked 5% of them.
Magnus, yes, yes and yes ground and near effects are serious, for hi res you need to image over greenery (no tarmac, no walls, no roofs etc) because you must have seen the heat haze above a hot roof or a mirage above a road on hot days. So image as close to dawn as you can before the heat builds up. People also say at the other end in evening too but I find the ground still too hot.
Yes, I would love to move house but can't afford it and probably never will. Taking the scope up a mountain would be nice too but a big faff every weekend if it is sunny. Far nicer to just walk out the door. So I am filled with hate for those house builders who built homes on grade 2a agricultural land which is protected by the government for growing food. Obviously in years to come we won't need agricultural land to grow food? but we will have houses to live in but no food to eat.

Re: My first love (C11 30th May)
Hi Alexandra,
I appreciate your advice about seeing and ground based effects. I wish I could have my own observatory in a great location somewhere. I sometimes think that with your enthusiasm and interest you could make a contribution to our knowledge of the magnetic and physical workings of our sun. Maybe you could work for a dedicated solar observatory somewhere, you would be perfect. A nice sponsor like Elon Musk or Jeff Bezos could be reading this and chip in and contribute a solar setup for you somewhere, I hope so.
Kind regards,
Magnus

Re: My first love (C11 30th May)
Magnus, if I won the lottery the first thing I would do is move house, then build a solar observatory, then make it publicly available for anyone on Solarchat. If I owned fields around then anyone could camp and stay and we could have early morning Solar fests every day. However, I am sure the UK weather would then become the wettest in history money can't buy cloud removal what a dreamer I am

If I understand correctly, the top image is a color version of the bottom one?Montana wrote: ↑Sat May 30, 2020 11:00 am This morning I was out and set up early by 08:15 BST and went back to my first love...
Could I replicate last years white light at 5x Powermate, oh yes I could. I had 30 minutes of pure heaven watching the video feed. Like normal they don't quite stack like the video but this for me is pure delight. I could do WL forever

(I suppose that you used Levels/Curves in that one?)
Looks like you used a small sensor for getting such a tight frame on the C11?

Re: My first love (C11 30th May)
Hello NF,
Yes the top one is just a coloured version of the monochrome for appeal I used Photoshop Levels, then used the colour balance tool to adjust further.
I used a ASI174 camera so the chip is quite large but you have uncovered my flaws about half the frame is removed because the drift with my EQ6 at this high res with the 5x powermate on the C11 is terrible, so after the stack only the middle section is stacked and the edges are all blurred. I really must sort out my bad tracking!
