The October 2020 Challenge is now open. The target is M33 The Triangulum 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 October 31, and I will try to announce the winner sometime on November 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.

Ok, so this was taken a bit early, July 19th 2020 so really do not want to go back for it. Although I should, there is not much data on this. This was taken with a 6" Astrograph guided with an Orion guide scope. Main camera is a QHY168C and the guide camera is a QHY5III224C run by APT and PHD2. It is 25 frames of 120S stacked and processed in APP and PSE20 with Topaz Tools.

Even though I am new to AP, I have had a really hard time with this target. It seems like Light Pollution really makes this one harder because the spirals are so dim?

 

This is several hours of integration time on a DSLR unmodded taken last month

I also tried to capture a 2×2 mosaic of M33 last weekend, mainly to practice with mosaics. Planning and capturing went well, which is good. I have 248 of 2 minute subs. But it was full moon only 30° away of M33. The glow and gradients are so terrible I can't even make a single pane look any good. A cup of good data is better than a huge pile of garbage.

This was a fun target to capture. I took this target at Cherry Springs State Park, in PA. The night was cold and got down to 29°F. I woke up to frost all around me and a very cold tent. This along with a clear sky was a welcome treat.

 

Acquisition Data

  • Telescope: Explore Scientific ED127 Air-Spaced Triplet Apochromatic Refractor
  • Camera: ASI2600MC Pro
  • Guide Scope: Orion ST80
  • Guide Camera: ASI290MM Mini. Dithering every image at 1 pixel each time.
  • Mount: iOptron CEM60
  • Software: NINA for image acquisition. PixInsight used for stacking and editing. Imported to Photoshop for final touchup and watermarking.
  • Other Accessories: AstroZap Dew Heater, Starizona ApexED 0.65 Focal Reducer/Field Flattener, MoonLite CFL 2.5" Focuser, High Res Stepper Motor, V3 Controller, Pegasus Astro Power Box Advance
  • Filters: Optolong L-Pro 2"
  • Exposure Time: 5 hour 50 minutes (70 x 300 seconds) -20°C.
  • Exposure Start: 22:41
  • Date: Sept 19, 2020
  • Location: Cherry Springs State Park, PA, United States

 

Processing Info

I took 72 frames at 300 seconds each. I had to throw away about two frames. Otherwise, I could have had a full 6-hour image. I stacked the 70 light frames along with 50 dark and 50 flat frames in PixInsight

Earlier in the night, I was having issues plate-solving due to a simple error on my end which took me two hours to resolve. I could have had a much longer image if I hadn’t run into any issues. As they say, astrophotography is a learning experience every time you set up and get started.

The following processes were performed in PixInsight:

  • Dynamic Crop
  • Dynamic Background Extraction
  • Background Neutralization
  • Color Calibration
  • Photometric Color Calibration
  • MultiScale Linear Transform
  • Histogram Transformation
  • LRGBCombination
  • Curves Transformation (X2 with a range mask. Inverted mask for the background and then non inverted for the target)
  • Color Saturation
  • Curves Transformation (X2 with a second range mask. Inverted mask for the background and then non inverted for the target)
  • Morphological Transformation (Generated StarMask using default settings)
  • Local Histogram Equalization (Performed with a range mask)

Here is a link for the full resolution image and more details

Here is my entry for this month.  The data was collected on 10/13/2020.
Equipment:
ZEQ25
Celestron Omni XLT150
Explore Scientific HR coma reducer
ZWO ASI294MC pro
 
Image info:
80x30 sec at gain 200, dark and flat applied.  Unguided.
Collected in Sharpcap pro, processed in Siril and Gimp
 
M33 is roughly in the direction of Baltimore from my location, so I had a pretty bad light pollution gradient to deal with.  I pitched about 20% of the subs due to poor FWHM.  I have a guide scope on order and I'm hoping to improve my FWHM and percent of subs that I keep.  I'm sure it's going to be another learning process.  I'm planning to use my ASI224MC as the guide camera.

Here is my rendition of M33 

 

10-18 M33 LPR 120Min STCrLMJ CN.jpg

 

Capture details;

Date & venue : October 18, 2020; from my backyard in Houston Texas suburbs, 

Mount : iOptron CEM40 with ipolar scope, 

OTA : Stellarvue Access 80mm ED refractor fitted with Stellarvue Field flattener & UV/IR cut filter,

Camera : Ha modded Nikon D5300 camera at ISO 100, f7 and total 2 hour exposure (120x1min),

Subs integrated in APP (Astro Pixel Processor) and post processed in StarTools. 

Guiding - None (Unguided). 

 

The galaxy came out surprisingly well considering that early subs were taken when the galaxy was only 22 degrees up from eastern horizon. 

 

Stay safe ...... Anil

Hi all,

 

So, much has changed in 2 years since we last did this target.  If I recall, October of 2018 was my first time imaging with a coma corrector (and no Barlow), and one of the first with an autoguider.  Imaging was done with the unmodified Nikon DSLR at max ISO (12,800), mostly to keep the exposures shorter than the errant excursions in tracking, and partly because I was still new at this.  Single night, 40 minutes total integration, first time trying to figure out the calibration file processing.  See https://www.cloudyni...-2#entry8968502

 

Fast forward 2 years.  New scope, new imaging camera, new guide scope and guide camera, new at-mount computer and all its software.  Same mount (!), but a lot more experience.  This is, however, only the second image with the new camera (ASI2600MC-Pro).  A combination of 3 nights' work, I'm still trying to figure out the best settings (e.g. gain vs exposure) and operating techniques (focus needs a bit of work), but this is at least a local plateau.

 

Imaged 9/24, 10/11, 10/15, 2020

Telescope:  Stellarvue SVA130EDT (130mm f/7, no reducer or flattener)

Camera:  ASI2600MC-Pro; 2x2 on-camera Bin, -5C temp

Mount:  Celestron AVX

Guider:  ZWO 60mm f/4.6, ASI174mm Mini camera

53 x 4 minute Lights (3 hrs 32 min total), gain 300, offset 50; few dozen flats, dark-flats, darks, bias

Acquisition software CCDciel, plate solving ASTAP, guiding PHD2, all on Raspberry Pi 4B

Stacked in DSS, processed in StarTools

Another monthly challenge and another challenge for me!  I took subs for this target in September and very little of it was useful, due to thin clouds and trees.  I took subs again on October 13 and had to tear down in a hurry due to an incoming storm so I didn’t take any flats and there are quite a few dust specs in the subs that I had to deal with.  Decent data otherwise but I am still learning how to process LRGB and have it look right.  Please PM with any processing suggestions.
 

Scope: AT72EDII 

Mount: Celestron 6SE wedge and pier mounted

Camera: Altair Hypercam 183M Pro

Filter wheel: Starfield high speed 5x 1.25”

Guide camera/scope: QHY 5LII-C/QHY mini guide scope
