Thank you for the photographs. The daylight images of Saturn are very impressive.

Daylight captures of Venus and Mercury, 11 March 2025 from Pensacola, FL. I used a Note20 running Astro Capture, ASI290MM with 742nm IR ProPlanet filter, and my 50+ year old C8.

Some daylight planetary images from 5 March 2025. I shot Jupiter and Mars about 20 minutes or so before sunset. Over the years daylight planetary imaging has become something I just like trying. Venus is always easy and quite visible in the finder. Jupiter is harder but still usually visible in the finder. Saturn and Mars are difficult, I've never seen either in the finder. Mercury is usually not too hard, once I sync the mount to the sun, the GoTo usually puts it in the field of a 32mm eyepiece. The camera and eyepiece are not parfocal, so I have to practice switching from eyepiece to camera with something easy like Venus. Bright stars are surprisingly easy, the pinpoint provides exceptional contrast with the sky background. Depending on the season, I use Capella or Vega to check collimation, both are easy to catch in daylight.

 

These were all taken with a Note20 running Astro Capture, ASI290MM, and my 50+ year old C8. For the planets, a 742nm IR ProPlanet was used. No filter for Capella.

Wow, these are fantastic! It's always impressive to see what can be done with daylight planetary imaging, especially with a setup that includes a 50+ year old C8!

 

Also, that's a great point about using bright stars like Capella and Vega for collimation checks.

 

The images themselves are excellent, especially considering they were taken so close to sunset.  The detail on Jupiter is impressive and Callisto is clearly visible. And using Astro Capture and the ASI290MM is a testament to the capabilities of modern smartphone astrophotography.

 

Thanks for sharing your experiences and these inspiring images!

Dear Majinsoft,

 

I've just downloaded the Astro Capture Android application and I should say that it's great! Frankly I didn't expect that my humble phone could get real time preview of my ASI camera.

 

One question, if you don't mind: both the preview and the saved TIFF images are grey-scale instead of color, is there a setting which I can change to get color images?

I am using an ASI 585 MC Pro color camera.

 

Kind regards,

 

Andras

Dear Andras,

 

Currently, Bayer-patterned images are displayed and saved to optimize performance. Debayering, which is required to reconstruct a full-color image, can be performed on a computer. 

 

We understand that in-app debayering is a highly requested feature and it is planned for a future update. However, I am unable to provide a specific timeline at this moment.

You can use OpenCV easily for bayer to rgb conversion. It has well optimized functions for it

Thank you, it makes sense to avoid the processor load on a mobile device.

I will try to save a FITS file and Debayer it with Siril.

Yes, this is the current suggested workflow.

Thanks for the suggestion, is very welcome.
