Advanced Request Planning (SPA-1-CMOS)

[Phil Misiowiec]

I'm considering capturing the Polaris Integrated Flux Nebula using SPA-1-CMOS and would like your advice.

1. Ideal sub length. To pick up the IFN, thinking that at least 300 seconds of exposure would be necessary. I'm just concerned about Polaris being overexposed. Perhaps this is a scenario that requires at least two runs, using varying sub lengths. Note: there's already a series of observations in the system that were captured in 2021 with the SPA-1-CCD (FLI PL16083 camera) at 600 seconds for reference.

2. When imaging at home (Bortle 6/7) with cameras that have the IMX455 or IMX571 sensor, I find that I can get great images without using a luminance filter and applying BXT. I'm considering doing the same here. Thoughts?

Thanks,
Phil

Hi Phil, 

I have some frames made with SPA1-CMOS with the Polaris in the field. I will send it to you shortly via email that you can check it and decide what's best for your session. 

 

Clear Skies,

Ernesto

Thanks, Ernesto! The 300s subs look nice - Polaris isn't blown out and you can see some of the IFN dust.
