Re: Today's "slow" SUN (20190718)

Almost nothing to see? Except for a near perfect solar disk! Beautifully executed, Pedro.

Re: PST control box replacement various versions

Thanks Mark.

I took one final image with the SME-40 + Quark Combo trying to get the most detail out of this little 40mm scope that I could today. It's way over sharpened and not quite on band but it shows the feasibility of the setup.

Re: Quark Users

Too bad about that Quark, Stu. I'm glad you decided to send it back even though your image looks great using a flat. My first Quark had a very smooth even illumination but failed to produce much contrast. My second Quark was not so evenly illuminated across the field and produced odd reflections aro...

Re: PST control box replacement various versions

I imaged today through haze but no clouds to test the current setup using the SME-40 etalon and a Quark Combo, as seen in the previous post. The extension tubes were shortened by 15mm and the Powermate extended slightly to reach focus. A circular polarizer was added to the front of the Quark and a 3...

Re: PST control box replacement

Another cloudy, rainy day and a perfect opportunity to reconfigure the PST. Starting from where I left off I added a Quark Combo. This setup has a SME-40 etalon on the front of the PST, various adapters and extension tubes, a 2.5x Powermate, and a Quark Combo. No control box or the main PST etalon. ...

Re: PST control box replacement

The focusing eyepiece holder was replaced with a non rotating helical focuser. This made focusing much easier but not necessarily any sharper. This PST is double stacked with a SME-40 etalon on the front end. With all components readily accessible I decided to remove the main PST etalon and reconfig...

Re: PST control box replacement

Before another imaging test I decided to take a quick look using some WO binoviewers. Not much to see today but the setup worked and focus was achived using a 1.5x barlow in front of the binoviewers. Image below. Dodging clouds, I captured an image using the straight through setup pictured in the or...

Re: PST control box replacement

Here are a couple images taken to test the modified PST. This arrangement works well but I don't see much of an improvement in image quality over the stock setup. I will be adding a non rotating helical focuser soon. That should help with the ease of use. Phil Jack, How did your mod perform? . 20190...

PST control box replacement various versions

The weather here in Florida has been lousy for solar recently and the Sun is so quiet. Naturally, it was a good time to take something apart and fix it. This time it was the PST. The control box, while brilliantly designed, has been a source of frustration for me at times so I decided to try a more ...

Hi Alfred,

Here is a pic of the setup. These images were taken without the Daystar Combo. It was replaced with an extension tube.

Re: June 1st images

Valery, you are absolutely correct. I did set the etalon temperature approximately 1.5°C hotter (red) that normal.

Re: May 26th

All good images, Brian. The orange one is particularly striking to me. I see that you haven't lost your touch after three weeks. After I took some time away from imaging, it took me a while to get back in the groove.
Best of luck with the crops.

Brian, it seems like both prom groups are being drawn towards the disturbed region between them.
