I just received delivery of a Solar Spectrum RG-18 0.3A etalon.  Mark at SS says the etalon is closer to 0.25A.  The RG models are supposed to be more uniform across the entire field.

The day started out mostly sunny, but by the time the sun was visible and I was set up and ready with an eyepiece bam, clouds for miles.  I did some yard work and kept an eye to the sky.  I figured I would be able to get some visual in so I could make sure everything was working.  It took about an hour and I was able to get a quick peek for about 2-3 minutes.  I had to figure out the spacing to get to focus so that took a while.  I went back to work an finally I could see that the clouds were thinning out enough that I would possibly be able to image.  These are the first I completed processing but I was able to capture more.  The visual is stunning!  Details really come alive. Filaments were dark and well defined. There doesn't seem to be a noticeable sweet spot. There was a nice filaprom that I cant wait to process.

The following are images of AR 2816 using a CR-6 at F/45 at the etalon and F/23 at the camera (ASI174)

Nice capture James. Great for first light, that looks like it will be a winner.  Anxious to see what you get when you sign that treaty with the cloud gods for new equipment.

For two days I battled with clouds.   I shot that one you shot for a little over an hour, 165x350 frames.  Still trying to do it some justice.  Clouds and seeing are making the assembly and contrast grading challenging.

Ah yard work... glad we now have a unit!  Sounds dangerous to keep an eye on the Sun and mow at the same time..... lovely images James

Great stuff James. Clouded out in the Sunshine State for the next three days. Look at all that stuff on the disc. BUMMER!

Thanks, Astro! My yard is not that big, but after winter there's plenty to do wink.gif!

Thanks, Chuck! I think I paid for it the last 2 weeks of clouds and yesterday was no bargain. Just about an hour of sucker holes.

There's no grass yet to mow, Peter! I was mostly taking the cover off the pool and cleaning the leaves. Thanks for the comments!

 

Beautiful James.

Thanks, Maurits!

Thanks Warren! It's amazing in the eyepiece too.  My Quark was good, but this just blows it away.

Thanks, Hax!  Can't wait for some good seeing.

Thanks, John! Don't worry, looks like more stuff will be there when it clears up.


    Nice setup! 

Thanks, Larry!

Thanks, Lorenzo! I waited a while for this.

Thanks, Harold!  I don't think I will rival the Unigraph wink.gif  , but it works very well indeed.

 

I went over the limit for quotes in a single post!!

 

Thanks for the likes!

 

A nice filaprom

It does indeed seem a little narrower than 0.3A based on your images with the relatively subtle double limb. Even at f/46, that's pretty narrow. Congratulations.

Thanks, George!

 

Here was a huge filament on the Northern limb.  Sorry for the orientation.

Awesome!  Love the images, they do indeed seem very flat! 

 

How long did it take for you to get delivery after ordering?  I just recently put in an order for a 0.3A solar spectrum (though I couldn't quite swing the research grade so had to settle for a cheaper option:), and am curious how long the wait might be.  I've heard everything from weeks to months, lol.  Don't want to rush a good thin, but just curious.

 

But I love the images, please come back and share more!

Thanks, James!  I really enjoy your animations and the level of detail of the spicule and prom movement.  You must have some excellent seeing in HI.  When I ordered at the end of January, I was told the same thing between 12 weeks and 6 months.  I then got an email that since it was a small etalon that it should be easier to source.  By the time they got my down payment to the time of delivery it was 11 weeks.

 

I still have a few more images to process and I will post them here. Thanks again.

Last two images from Sunday.  Hopefully, this weekend has some clear weather.
