Can’t use the new AstroShader

Used to take T-CrB (mag 12) nova everyday, while weather permits in the past more than a year. Ever since after version update, since late June., the updated app can not produce good enough picture. Can you provide the older version such as the 1.0.38, the version just before the v1.2.0, so that I can continue to picture the T-CrB. Thank you.

I can’t take clear pictures of the planets anymore, yet it still works a bit

I used to be able to take good clear shots of all the planets with this app such as Jupiter and Saturn. Nowadays, whenever I try to do Saturn again in the morning, it would often appear very blurry no matter how hard I try to change the settings in the app. But it would work for some of the other planets such as Mars, Neptune, and Uranus. Sometimes even Venus too. I’m curious if there is a specific setting besides changing the ISO and exposure time to make them clear again or if there needs to be some additional update to compensate for this problem. Please let me know if there’s anything I can do because I want to take clear photos of the planets with my telescope like I once did before. Thank you so much for your understanding. And please fix it to make it the same good old version again. I beg you developers, please!

Response from developer

There was an issue with v1.2.0 affecting alignment v1.2.1 has resolved this!

Love it

Great app

Doesn’t stack

I tried for an hour to image M13 with this software. I tried different amounts of exposures, exposure times, iso, and stacking methods. Every single time I tried imaging all I got were long stretchy blobs and star streaks. I could clearly see a good image during the capturing process but as soon as the post processing begins it just turns in to streaky nonsense. The app doesn’t even have app support to contact someone for help.

0/5 stars.

FAQ

What is AstroShader used for?

AstroShader is an application designed for capturing, stacking, and editing astrophotography images. It allows users to take photos of the night sky and process them directly on their mobile device, simplifying the workflow.

How does AstroShader differ from traditional astrophotography workflows?

Unlike traditional methods that require transferring images to a computer for alignment and stacking, AstroShader performs these processes live during image capture. This integrated approach streamlines the entire astrophotography process.

What are the key features for capturing images?

Key capture features include setting the number of exposures for stacking, exposure time, ISO, white balance, camera type, and a countdown timer. It also offers manual focus control and the ability to pause capture to reposition equipment.

What editing tools are available in AstroShader?

The app provides a comprehensive set of editing tools, including image stretching, background extraction, multiple histogram curves for tonal adjustment, sharpen layers with blending, brightness enhancement, saturation, black point, temperature, and tint adjustments.

What file formats can I save my images in?

You can save your edited astrophotography images in various formats, including HEIF, PNG, JPEG, and TIFF. The option to save as a 16-bit TIFF is particularly useful for further professional editing.
