Hello!

 

I have a fairly basic setup but am hoping to continue to improve the quality of the images I am able to capture. I am using a Celestron 127 SLT with a Nikon D3400 and a 9mm focal length eyepiece from my rooftop in NYC. I am pretty impressed with what I am getting so far, but I know I should be able to capture higher quality stacked images, especially with a 10+ minute 1080p/60fps video and AutoStakkert!2. 

 

Does anyone have any advice for how to capture 1:1 pixel data / live view data from the camera? From what I have read, that might be a key I am missing to really boost my images.

 

I looked through the forums and have not found anything. 

 

Thank you for the help!

To do true high-resolution planetary imaging, you really need 1:1 pixel resolution.

 

Unfortunately, 1080p video trashes that because it takes the 6000 original pixels on the sensor, and downsamples/decimates them to 1920 pixels.

 

You can theoretically get something closer to 1:1 with something like BackYardNikon, but Nikon slows the framing rate way down in Live View when zoomed in, and the jpeg compression of the live view makes them nearly unusable for high-resolution planetary work.

 

Sorry.

 

Jerry

Re: planetary lucky imaging

AFAIK, Nikon DSLRs (the entire line) do not have the trick mode (e.g., central region 1:1 crop) feature 

   <--- actually (again AFAIK) recent Canon DSLR also no longer have that feature any more

 

Re: Deep Sky Objects

- LiveView (in any form) is not the correct approach

- high frame rate HD video type of capture then stack is not the appropriate approach

 

BTW, D3400 is in the low-tier (a.k.a. teaser tier)  in the Nikon DSLR line-up, many advanced feature for AP are simply missing.

Really appreciate the help here. Unfortunately, it looks like I bought the wrong camera!

I caved last night and bought the Neximage 5 by celestron. Bought on amazon, though so hopefully if I don't love it I can return it. I was thinking of getting a second hand T2i, but realize that the tiny FOV would still mean i would likely still need the laptop to control the camera without bumping the telescope too much. I will let you know how this works out!
