You know Matt that 80mm is the reason for all this rain.I've been thinking about getting a Cak diagonal so I guess that may also be a factor.Seriously though as a kid in the seventies it was always raining here on the coast from Dec through till late February March.

Derek Klepp

Got this in a 10 minute window seeing was not good so omly used 3x Barlow(top) and 2.4ext(bottom).As I don't have PS can someone direct me to some merging programs with associated Tutorials. These collages are a bit rough Alexandra here is an Inversion of that greyscale Sun pic it turned out OK

Derek Klepp

That camera you have is amazing. Are they still manufactured? I cant find much info on it. They make a new version but it does not have the occulting function which allows me to capture in negative(except for the proms which are positive.http://www.myastroshop.com.au/ Have a look here.But like I sa...

Derek Klepp

Very nice Pedro a lot of time and effort has gone in to perfecting your system thanks for the schematic.

Looks promising

Derek Klepp

Thanks Dennis and welcome. Should be some good views coming up

Derek Klepp

Youv'e sold me Pedro I think I will get one myself thanks for the pics and look foward to more.

Derek Klepp

Quite alot going on there. That first pic is awesome. You definitely get the most from your PST DS

Derek Klepp

Some very bright areas there.

Derek Klepp

Thanks Mark just had a quick look at that larges Sunspot moving into view Too many clouds here as yet.

Derek Klepp

Looks promising

[quote]Very interesting! have you tried the best 20 frames on a bad seeing day? also on a Ha sun at sunset? I think this would be a good practice test. Alexandra[/quote Now Alexandra that sounds a bit like an Analysis of Variance test .Your scientific training is evident here. In my Random stacking ...

Derek Klepp

Definitely alot of detail there Ted. That rain has turned up here this morning

Derek Klepp

I put this together for a group that uses the same type of camera I use but thought it may be of interest

Derek Klepp

Great pic Andrea. Now isn't that amazing it is also my birthday. Look foward to the Prom shots.
Cheers hope you had a great day Derek

Derek Klepp

I was nearly tempted to try one of these but will stick with the 127mm.Welcome back downunder lots of rain here at the moment. Look foward to the results

Derek Klepp

Its amazing what the eye percieves. Experimented using a 3x Achro Barlow today and when the Prom was rotated there was a Bird and a tree.As an aside I thought the clarity achieved with this set up was quite good.Also a pic with more surface detaildue to different shutter speed and what I first thoug...

Derek Klepp

2 and 3 are definitely sharper.Brian I don't get overly worried about processing its just good to get a result. I hardly ever use the same sharpening in wavelets. I adjust till it looks grainy then back the sliders off till the noise fades.I have only just recently started using sharpening in Picnik...

Derek Klepp

Thanks all I'll have to go and study Jims pics in more detail. As an aside I just ordered "Astrophysics of the Sun" only $6.00 on Amazon second hand of course but good value nonetheless

Derek Klepp

Thanks Walter glad you got a similar capture to me it's good to get these things in perspective especially if several of us image the same area.Its always amazing what our eyes would like us to see.
Derek

Derek Klepp

Seeing was sporadic this arvo but captured some interesting proms

And finally in this pic you'll see some nice rounded black dots at about 12,3 and4 around the Sunspot. They are not artefacts I checked the avi does anyone know if they are Ellerman Bombs

Derek Klepp

Very nice Pedro you are certainly enjoying that 60mm Lunt

Derek Klepp

As an aside I was surprised at the middle prom shot on the left it was not till I processed it that I realized its arching structure. Also notice the two brighter flaring structures present. By the time I came back to this area most of the detail had gone.I guess that's why a lot of us enjoy this So...

Derek Klepp

Hi all got home early and took a few quick pics which I assembled in a collage I had plans to leave the scope out and do more but the temperature soared with the temp in direct sunlight nearing 45C+ . I decided to have a siesta in the comfort of air conditioning.
Derek

Derek Klepp

Thanks for the pics of your set up Chris considering the aperture thats great granulation. Just a shame the weather wasn't more co-operative

Derek Klepp

Looking good some great additions there. what do you estimate your total costings were for the scope and the amount of time it took to put it all together

Derek Klepp

Today at lunch set up the Lunt for a few quick Avis which I processed after work. Just for something different I processed the 1000 frame avis in Registax 5 enlarged them to 150% then joined them together in Picasa in a collage using the retouch tool to merge the join. I then put the collage in Picn...

Derek Klepp

Even one Avi is better than none Jim this really was an interesting area. Thanks for your take on it

Derek Klepp

Peter that first Prom shot is very interesting so many different features together.

Derek Klepp

Good to see come on Chuck we're not that way all the time.

Derek Klepp

Very nice Mark always look forward to your disc shots

Derek Klepp

Well Chris very interesting. I use that camera (A different brand GSTAR CLR) for live view with a 16" GOTO Dob and the views are very good. Mind you I have it going to a 76cm CRT TV. Being colour it is of course no good for the Sun but I use the B/W version which is a much better product in ter...

Prominence

Derek Klepp

Love that looping Prom

Derek Klepp

I think the Prominences are very good I'd be happy with them

Derek Klepp

Nice capture Walter

Derek Klepp

Hi all managed to capture this interesting area this morning. It was shot through light clouds and thus achieved an effect I can't often replicate.Also a few Proms rotated for best viewing. And finally a shot with the 5x powermate +1.6 extender using a flat. Unfortunately clouds came in before I mov...

Derek Klepp

Always enjoy these multiple wavelength compositions thanks Michael

Derek Klepp

I like the Disc shot Brian

Derek Klepp

1 and 6 very good as are the rest. Good to see you getting plenty of Sun

Derek Klepp

I like one and two good to see you worked it out

Derek Klepp

Ther're all good Pedro thanks for posting the comparisons

Derek Klepp

Thanks for the pics Mark

Derek Klepp

As for your response from work that is why we are all here keep up the pics we all appreciate them.

Derek Klepp

Looking foward to your pics Mark total greyout here. Even the fish aren't biting

Derek Klepp

Michael good to see you here. I'd be very interested to see more of your Lunt B1800 CaK shots as I am debating as to whether I should get that model or the B1200 for my 127mm F 7.5 Refractor.

Derek Klepp

Hi Andrea, Nothing special really, for prime focus I process in Avistack 2, then use iterative Unsharp mask at 0.5 pixels, 25% and 0 threshold for around 14 times. For the 2x Barlow it is the same but with a pixel of 1. For my prominences, absolutely nothing happens! sometimes I wonder if anything ...

Derek Klepp

Great pics worth the wait. Hope you get some Sun this weekend all rain here today.

Derek Klepp

Andrea that prom shot is fantastic thanks for the pics

Derek Klepp

The focuser is not motorised I focus using a monitor just inside the shed . Then go into the shed to capture. Yes Chris your right too many cables I,ll have to duct them. Thanks all for the feedback .
