Dolphin Head Nebula (SH2-308) - 15 degrees above the horizon


jypeng@...
 

Hello
I like to share one of the difficult targets I acquired recently.
This Mach2GTO was tracking (20 minutes guiding) my target very well just 15 degrees above the horizon. No modeling this time due to my model is all above 25 degrees above. 
Excellent mount, Great job, AP!
Thanks,

Wow, that is one beautiful image. I vote for it as the image of the day. Out of the many details in the image, I was most impressed by the near transparent outer shell and the difference between it and the inner more solid material of the nebula.

Excellent image.

Looking at your equipment and numbers, your camera is ASI6200MM which uses Sony IMX-455 sensor. The pixel size is 3.76uM but you said 1.88uM?

Captivating!  Well done!

The image was likely resampled.

Superb image.  I know how bad the sky is from Palo Alto, living in SJ.

Hi Peter,
I run PI PhotometricColorCalibration on the drizzle integrated version. The final version was resampled 50% to the original scale. Thank you for your comments!

Thank all of you for your nice and encouraging comments! 
Really enjoy use Mach2 and get a lot of good photos since I own it.

I recently used the  Mach2 gto  with the ASI air pro and they worked fairly well. Uou need to connect it as the gtocp2 .(strange but teie) and you must have the USB cable connected from the control box to the ASI air box usb  to allow it to connect it wirelessly. Of course you 
Have to configure the gtocp5 control box to station mode and link to the ASI air wifi.

Only the  go home button on the ASI app does not work and you have to use the keypad to get it to go back to your correct park position. Not sure if there is some step I missed . 

How this will help those  planning to use this setup.
