Monsieur Klein has acknowledged that this was a prank. That photo is not Proxima Centauri, it is a piece of Spanish chorizo.  https://www.cnn.com/2022/08/05/europe/scientist-space-image-chorizo-intl-scli-scn/index.html


AP27TVPH with 92 Stowaway?

Dean S
 

 Hi all,

I am currently using the 27TVPH with a ASI2600pro and a 130GTX. Getting good stars and nice image scale. I am interested In trying it with my stowaway but not sure if it can be adapted to fit? Just want to experiment before deciding to get the dedicated AP reducer.

Thanks
Dean

Re: Spacing options?

I don't see why you couldn't cut a shim out of shim stock that fits between the end of the flattener and the backside of the pp adapter.

Aha,

I am with Chris.  I am getting one!  I can't image at night due to the storms, but during the early to mid moring, that is avaible to me even during the summer.

Thank you Alan. It was a wonderful eyepiece view. I am on the lower part of the solar learning curve. Your work has been inspiring for years. Hoping to develop my animating skills for prominences like this. Glad you had a chance to view the prominence. Clear skies and take care.

Very nice results… must have been great to enjoy this prominence from a good location. I was watching this fabulous eruption from the various Ha worldwide fields and was thrilled to get a morning cloud break allowing me see it with my own eyes.

Clear skies!

Hello APUG,

Our family vacationed in Surfside Beach, SC this past week. I had envisioned a video production celebrating the “Summer Sky”. I planned on capturing the beauty of the sky with clouds, stars, Milky Way, Sun, and Moon. I brought my Astro-Physics Stowaway and Daystar Quark Chromosphere Eyepiece along for hydrogen alpha views and images of the Sun. Boy was I in for a treat. I viewed/imaged the Sun every morning and was taken aback with the views on August 3. The prominence was fantastic and lingered well into the next day. Below are the images and links to the video production. I will soon have a video reviewing and discussing viewing/imaging with the Daystar Quark Chromosphere eyepiece. So far, it has been a blast since I picked it up in December. Clear skies and thanks for stopping by.

Thank you Chris. I always regretted selling my Coronado solar max/TV 85 combination years ago. I am no expert on solar viewing/imaging, but I am enjoying this combination. The eyepiece views are fantastic. I do yearn for a full disk view, however.

Thanks Chris. I am really enjoying it. Just need to retire and leave everything setup daily.

Re: Jwst image of Proxima Centauri

Yes, the disc of Antares has been resolved using Earth based telescopes:

https://www.eso.org/public/news/eso1726/


Re: Jwst image of Proxima Centauri

M Hambrick
 

A couple months ago someone on Cloudy Nights posted a link to an article claiming to show telescope images of a nearby exoplanet. I don't remember any details (telescope, stellar system, etc), but the "image" of the exoplanet showed it in the partial (about 1/2 full) phase. I thought to myself, "Wow ! That must be a powerful telescope to be able to see an exoplanet in the partial phase."

I challenged that this "image" might have been an artist's rendering instead of a real image. The article and all traces of that post were pulled from the forum in less than an hour.

On a more serious note, has Hubble, JWST, or any earthbound telescope ever been able to actually resolve the disk of a star other than the Sun ? I once calculated what the angular diameter of Arcturus would be if it were the same distance as Proxima Centauri and got something like 0.001 Arc-seconds. 

It is probably a safe bet to say that at least for our hobby, the classical physics definition of all stars as point sources of light is safe for some time to come. Unless maybe Roland decides to make a 1-meter diameter APO scope :>)

Another amazing image from the JWST: 4.2 L-y distant

Remarkable surface detail. It almost looks like it’s boiling.

No wait: it’s actually a slice of Chorizo 

Evidently even scientists sometimes have a sense of humor.

Re: M27 and filters: It's the colors, Dumbbell!

Barbara Harris
 

I love the unfiltered image because I love seeing it with the many background stars.  BTW, I have a similar setup with Meade LX200 16” with the Optec focal reducer on an AP1200. I have photometric filters since most of my work is photometry.

Thank you Emilio!  The Daystar Quark has a 4x Barlow built in.
