  1. To reduce reflections when taking a picture through an eyepiece with your cellphone, try adjusting the angle of your phone or dimming the surrounding lights. Great image, by the way.

  2. It’s impressive to see such a detailed capture processed entirely through an iPhone app like Astroshader; I’ve been experimenting with smartphone astrophotography using a basic adapter on my old telescope, but the results are often grainy. Your success with the Celestron 127SLT makes me wonder if better optics are my next logical upgrade—did you use any specific settings in the app to manage noise or exposure?

    1. Thanks for sharing your experience with smartphone astrophotography—it’s a rewarding challenge, isn’t it? For noise management with Astroshader, I found that using its stacking feature for multiple short exposures, rather than a single long one, really helped clean up grain; better optics like the 127SLT’s definitely provide a cleaner signal to start with. Feel free to share what telescope you’re using now—I’d be curious to hear how your experiments progress.

      1. Thank you! I enjoy learning new things. I just checked out this app, which was previously unknown to me. It looks like I’ll have something new to explore when the scope is busy on its own.
