March 17th - Ha

Post by MapleRidge »

Good day all...

I had a rather unique day on Thursday...clear skies and the temperature made it into the 18C range by mid-day...that's tight, no - sign ahead of the air temp :lol: The seeing was better too! It took a few days to get these images processed and posted as most of my spare time after work has been spent at the sugar bush making syrup.

The first images are full disks imaged through the LS80T/LS75FHa/B1800Ha solar scope, with an ASI1600MM + 1.6x barlow. The first image is a disk/limb composite with the limb inverted, and the second was made with enhanced gamma to pull the proms out without doing a composite. False colour palette applied:

I moved to the DS modded Orion EON 130 OTA to image the active areas in greater detail. The DS system uses a pair of Lunt pressure tuned etalons, an Astronomik 12nnm Ha pre-filter, the B1800Ha blocker, and a full aperture Daystar ERF. The ASI290MM camera was used for capturing the video clips. AR2965 was by far the most impressive AR, but there were several others as well as some nice prom activity. Most of these images are mosaics to cover the regions of interest. These were all taken at prime focus @ 910mm (F7).

First, AR2965 and filaments on the NW disk:

Moving south, is AR2968 and AR2970 and an other filament trailing off to the south of the pair:

The SE quadrant did not have any AR's, but a beautiful filament structure was present:

There was a new AR in the NE quadrant that hadn't been assigned a number as of yet, and it is shown in the image below along with several filaments across the northern disk:

After grabbing the disk features I moved on to image the proms, where the south-east and north-east limb showed the most activity.There were some smaller proms as well:

Since the seeing seemed to be more stable than the cold days, I added the Explore Scientific 3x focal extender to boos the scope up to f21 (2,730mm focal length) to try to pull more details out of the activity. The main AR's and prominence groups are shown again below:

I has some thin cirrus cloud drift in during the last set of prom captures, so the contrast wasn't as good as I hoped. The variation in the first image (mosaic) of the NE limb really shows it. The imaging session started with the FD images at 15:10 UT and finished at 16:20UT.

I was going o do some WL/CaK as well, but the clouds looked to be thickening so I closed up the observatory and went in for lunch before returning to work. I hope that you find these to your liking ;)

On another note, I received work on Thursday night that my new dome is ready to ship, so I should have it by months end. I need to finish syrup and get the weather to warm up a bit, then the dome can be installed and I can get the scopes re-mounted in their intended homes! My Gemini controller for the MI-250 mount was repaired this winter and has been waiting to be installed in the new observatory.

Take care everyone,
Brian

Great session Brian! Those closeups are really nice! Now I wish I would have tried an animation on that NE limb instead of the NW which showed hardly any movement at all! That "bridge" prom on the NE looks really cool.

Wonderful session Brian!

I particularly liked your 970mm and 2730mm shots. They are so crisp and clean!

Best regards,
Arne

Warren and Arne...

Thanks for your comments and feedback guys...always appreciated :bow

Warren, I wasn't paying a lot of attention to the potential for motion in the proms since I had limited time to image. If you pick one, it is like the lineup at the grocery store...which ever you choose moves slower than your second choice :o

Brian!

Wonderful job! I love these. What a nice run of images. I took the liberty of colorizing my favorite one. Just look how the chromosphere is disturbed around AR12965. You captured it superbly!!

Two thumbs up!!

James

Hi James...

Glad you liked these images and thanks for your feedback :bow

Your colorized version looks great, and the field of influence around the AR is certainly enormous.

Great set of images, Brian.

Good luck with the installation of the new dome (fun stuff).

You had a busy session, Brian. Really nice images.

Glad the observatory building project is still progressing. :)

Eric, Jochen, and Stuart...

Thanks for all of your comments on the session...very much appreciated :bow

Start, I will be glad to have the dome installed and the facility in use. It was talked about for the better part of 3 years but finally started six months ago. Once it is finished I will post a set of pics and story to go along with it.

Wow! what a fabulous collection Brian, top notch :bow :hamster: if only you could add the smell of the boiling syrup and it would be a perfect post :)
Glad to hear the dome is on its way :hamster:
