Hello everyone.

 

Last night I was able to capture Mars with my Celestron C8 and my ASI224MC camera from my backyard in the southwestern side of Puerto Rico.

 

Atmospheric conditions were superb last night although the ground not so good, while capturing we got hit by a 4.1 earthquake 😱

 

Here's the details.

 

Telescope: Celestron C8 SCT and a Televue 3X Barlow
Camera: ZWO ASI224MC & Astronomic L2 UV/IR Cut Filter
Mount: Orion Sirius EQ-G

This is a very good image, especially given you used a longer effective focal ratio that is usually best for your camera. The seeing was clearly excellent. Normally, a 2X Barlow is the best fit for a SCT and a ZWO 224MC camera.

May I ask how long the vids where that you took, and how many frames you kept?

 

What software did you use?

Processed the best 25% of 24,699 frames, It was a 4 min video in Autostakkert.

The workflow was as follows

 

  1. Processed the best 25% of 24,699 frames in Autostakkert.
  2. Color balance and stretch in Registax
  3. Wavelet sharpen in Astra image
  4. Contrast and Saturation adjustment in PS.

Those are the software I like to use.

Great image. I have a C8 and that’s what I am hoping for over the next few weeks - seeing allowing!

Thanks, definitely it worth the try and better that Mars is getting closer for its opposition in October 13th

Good work! That is the benefit of the good seeing we get here in Puerto Rico :)  

I felt the earthquake too that night. Thankfully not too strong. Let's hope it stays calm.
