The June 2020 Challenge is now open. The target is M51 the Whirlpool Galaxy. To reduce the number of stickies, please submit your entry to this thread.

 

For those having troubles locating the target here is a post that will help locate near by objects.

 

The Rules will remain pretty simple:

 

      Your Equipment

      Your Data, Captured This Season

      Your Processing

      One Entry Per Member

      Only post your FINAL image

 

To increase participation over such a diverse group, the winner will be selected by random drawing. Please feel free to start a thread requesting guidance on your entry prior to submitting it, the whole purpose of this challenge is to learn and compare on a common target. Entries must be submitted by midnight eastern time on June 30, and I will try to announce the winner sometime on July 1.

 

Note: If I am late announcing, gently nudge one of the moderators in a private note, it helps.

 

Please display an image in your post, not just a link!!

 

I hope everyone has fun with this one, and with that,

 

Let The Games Begin

 

**Disclaimer** - If the selected winner does not reply and pick a target with-in 3 days of the winner being announced, the Mods will then select the next target.

On May 8th 2020 under a 95% illuminated moon I attempted plate-solving for the first time. I chose M51 because it would be crossing the meridian and I wanted to see how well plate-solving would recapture the framing (if I was successful to begin with). Since I don't plan on imaging M51 this season I am entering the results of those tests, of which both were a success.

For 30 minutes under a near full moon I think it didn't turn out too bad!

I took the liberty of aligning all posted images and creating an animated gif of them. When a hires link was provided I took the hires. Apart from scale and crop nothing was altered. The order is random.

Here's my go at it from late April/early May with an almost full moon. This image is 60x20 sec frames (20 min. total) at ISO 3200 with my unmodified Canon 6D. The scope is a 17.5" f4.5 truss dobsonian tracking with ServoCAT and using a Paracorr II. 21 darks, 20 flats, 28 bias frames. Stacked in DSS, processed in Photoshop. Full size available on my Astrobin in my signature below.

This has to be a favorite target for many people.  Great work people!  Very much enjoyed looking through these.  This effort started at the end of March when I got RGB at binx2 and then waited for some better seeing to take luminance.  Kind of out smarted myself blush.gif.  Last night the luminance imaging started on the West side of the Meridian, where the  color data was taken on the East side of the Meridian. There was enough rotation difference between the two, that DSS would not stack the two sides together.  I ended up overlaying the two seperate results in Gimp, which gives an averaged picture instead of a cumulative picture.  Did not see that coming!  These were all one minute subs with luminance for 106 min at binx1,  and RGB fairly evenly split  for 220 min at binx2. Camera: ASI183MM-Pro.  Telescope:  8" f/4 reflector.  Mount: CEM-60 guided.

I got this image using a Sony A7RIII camera mounted on a Celestron C8 EdgeHD telescope.

I don’t recall all the particulars, but I think I stack about 9 subframes that were exposed for

thirty seconds each. I also used a .7 focal reducer.

Here is my rendition of M51, captured last night (June 11, 2020) from my LP filled backyard in Houston, Texas suburbs : 

 

6-11 M51 Crop 188Min LPR STCr1J2 CN.jpg

 

Capture details are : 

 

OTA : Stellarvue 105mm triplet refractor,

Mount : iOptron iEQ 30Pro - No guiding or dithering, 

Filter : 2" Optolong UV/IR cut filter mounted on a Stellarvue Field Flattener,

Imaging camera : Nikon D5300, 

ISO 200, f7 and a total integration time of 188 minutes (125x1.5 min),

Image scale of 1.10 arc-sec/pixel,

9 flats, 5 darks, Masterbias (made from 30 bias frames) and a Bad Pixel Map created in APP were used to calibrate the data. 

 

Data was registered, calibrated, integrated and cropped in APP (Astro Pixel Processor) and then further post-processed in StarTools. The final image was further cropped to meet CN posting guidelines and to show the galaxy pair better. Cheers ...... Anil
