Re: Zodiacal Light

Thx Lou, No problem, Glad you picked up on M31.

Just to let you know I had trouble posting, sent a request to Brian requesting help.

I was unable to toggle/activate the member post option/privilege, maybe b/c I'm new.

My Spring Challenge Submission was sent on June 20, 2022.

Hello Tom,

Thanks for sharing and for the detailed descriptions. Very impressive and well done all the way around.

Here are 3 galaxies I imaged this Spring from my backyard in Upper Moreland using an 8 inch F4 Reflector and a ZWO ASI174mm camera. The galaxies are:

NGC2903 a 9th magnitude barred spiral galaxy in Leo. 40 minutes total exposure.

NGC3184 "The Little Pinwheel" a 10.5 mag galaxy in Ursa Major. 30 minutes total exposure

NGC5907 "The Splinter or Knife Edge" an 11 mag galaxy in Draco. 44 minutes total exposure.

There is also an image of Venus & Jupiter at Conjunction on April 30th, from Cherry Springs state Park, when the planets were only 14 minutes of arc apart. This image was

taken with a Canon 3Ti DSLR camera with a 135mm telephoto on a fixed tripod.

And finally, there is a composite image of the Sun taken on June 20th 2022 through a Lunt 60mm Solar Scope, 2x barlow lens and a ZWO ASI 174mm camera.

Thanks for looking.

Fantastic Spring Challenge submissions everyone. It's great to see the increased participation for this season's challenge. Keep up the good work!!

Tracey and I were at BMVO for two nights at the end of April and four nights at Cherry Springs at the end of May. I was able to image a fair amount of all six nights with my recently purchased ZWO ASI2600MC-Pro color camera and ASIAIR (i.e. - Raspberry Pi based astro-imaging computer). I was learning the system and also experimenting with a couple of different OTA configurations to see what the results would be like.

I spent some time on Monday of this week to process five of the approximately eleven images I took during those evenings. I posted them in the Challenge (2022, Spring) folder in the "Document Library" part of the DVAA (per the link provided in the Astrophotography Resource Page. (I realize that some people posted their images directly to this thread and some posted in the Documents Folder, so I assume all of the entries will be combined at some point.)

Here's a list of what I posted in the Challenge (2022, Spring) Document Folder:

• M8, M20, M21 (TV101, CSSP)
• M51 (C6, CSSP)
• M57 (C6, CSSP)
• M64 (CSSP, C6)
• SN 2022hrs in NGC4647 (TV101 w-2X PM, BMVO)

Take a peak if you get a chance.

Clear skies,

Some incredible shots here already! I figured I'd toss in my spring project, the Eastern Veil Nebula. Open to all suggestions and critiques. This is my first time processing an image via PS, and my first time using my full set up.

Using a Vixen 80EDsf on a Skywatcher EQ6 Pro.

Here is my entry for the Spring Imaging Challenge

My target is NGC 4438, the Eyes galaxies, but due to the FOV of the image there are a LOT of DSOs in the image

- 9 Messier objects

- 50 NGC objects

- 62 IC objects

I have also attached the annotated image

Imaged at SOS field on Jan 26

35x180sec frames (no filter except the UVIR filter on the camera)

The pinwheel galaxy (Messier 101) located 21 million light years from earth as captured over 4 nights in late April / early May. It is unique in that you can view this galaxy "head on". In 2011, a supernova was also discovered in M101 and was visible in images in the 7 o'clock position of the galaxy's arms when it reached peak magnitude.

Acquisition details:

2 min subs with darks, flats and bias for total integration time of 116 min (no guiding)

Gear: Modified Canon EOS Rebel T6 with a Pentax 200mm Prime telephoto lens, iOptron Skyguider Pro, Windows laptop

Software: BYE, iPolar, DSS, Photoshop

Location: West Chester, PA

Here is my Entry for the Spring Imaging Challenge.

NGC4565 (also known as the Needle Galaxy or Caldwell 38) is an edge-on spiral galaxy about 30 to 50 million light-years away in the constellation Coma Berenices. It lies close to the North Galactic Pole and has a visual magnitude of approximately 10. It is known as the Needle Galaxy for its narrow profile. First recorded in 1785 by William Herschel, it is a prominent example of an edge-on spiral galaxy. (Wikipedia)

Image was taken with Celestron C6 SCT /F6.3/ASI533MC Pro/Gain 320/2 Min Subs/70 Min Total Exp

Lou,
Beautiful image and thanks for the PI workflow. It is always interesting to compare post processing techniques.
