First ever solar image

Recommended Posts

Seems like a bad image, I know but this is my first ever solar image with a Ha scope

I was wondering if any of you could give me any tips to improve these images?

I'm using a Lunt LS60THa and a ASI120MC (I know I should have a mono)

I did a quick stack and edit on PS to get this and I've noticed that it's out of focus.

I do find it hard to determine when it is in focus properly too

Very nice first go. Apart from getting an ASI178MM, which is ideal for this kind of imaging, I would have a look at some tips for processing here:

that's quite a good image, theres not a lot to focus on on the disc but if you go for proms first "if there is any on the day" it gives you something to focus on . well done. charl.

Worked on it a little more, not sure if it's an improvement

Looking good, what software are you using for capture and processing ?

Focusing is much easier when there's a nice Sun spot to focus on, hopefully some will show up soon.

I use Firecapture, AS3, imppg and then P'Shop.

As Michael said the ZWO ASI178M works well on the LS60, it's what I use and just about squeezes a full disc in at good resolution.

Second image looks pixelated.

I'm using sharpcap then AS!3 for stacking then registax and PS for processing

I think without a barlow, it's very undersampled and blocky but it's just so hard to focus with the barlow and no sunspots

I added a SW electronic focus motor to all my solar scopes......

This allows you to comfortably concentrate on the image while tweaking the focus.

There will be a guaranteed "sunspot" on Nov 11th.    😀

Hi, it does seem undersampled. I use the lunt 60mm but the zwo asi120mm. I also use a 0.5 reducer for full disk. I follow similar process, autostakker3, 25% stack, photoshop to add false colour. I use a 3x Barlow for closer images. ISS caught using the above. I'm new too to using the lunt, unfortunately there's not much going on. I've also added an electric focuser which really helps in focusing.

This has been my best shot at processing it. Have cropped substantially for the out of focus parts

Matt,

A bit over cooked...the actual surface is smoother and more flowing......ease off the wavelets and contrast.

Just my 2c.

I followed the full disk tutorial on daveys link. 

Think it looks much better now

There's no flats so it looks much darker in the middle

It's weird how one set of data can vary so wildly, just by changing the processing

I use an ASI 174 and ASI 1600 for solar imaging with my SM60/ED80, x2.5 PM.

I work at Unity gain (174 = 189 gain, 1600 = 139 gain) and Gamma = 50.

I never touch these again.Sun_091336.jpg.354995284e2bc03419380d3aadec684b.jpg

Using the exposure I push to get the histogram up to around the 90% mark.......

For proms, I leave the Gain and Gamma untouched but push the exposure to show the prom.....maybe, just maybe, for the fainter proms I'll push the Gain a few points......
