Testing the Svbony SV240 Multi-Narrowband Filter

By Naztronomy • Posted on 7/10/2025

I had the opportunity to test the Svbony SV240 Multi-narrowband filter for the last few months. Due to weather, I only had two nights of imaging with it! But I made the best of it. In the video above, you can see my thoughts on it but the gist of it is that it’s a cool filter but I don’t see myself using it every day.

Here is the result of NGC 6960 that you saw in the video. Also known as the Western Veil Nebula and Witch’s Broom Nebula:

Also known as the Witch's Broom Nebula, this was taken with the Askar 71F, ASI2600MC Pro, and the new Svbony SV240 filter. Total integration time is one hour.

I really like that the bright star there is not throwing out a massive halo.

Svbony SV605CC Astrocam Review vs the ZWO ASI533MC Pro. Same sensor but $200 less?

By Naztronomy • Posted on 7/3/2025

You all know that I like Svbony, mainly because they make affordable astro gear and t he SV605CC is no different.

It’s an astro cam with an IMX533 Sensor, the same 1″ diagonal sensor that we find on the ASI533MC Pro by ZWO but it costs $200 less! $599 vs $799. How does it perform against its rival?

From the thumbnail, you can see that it’s missing the USB hub in the back but that’s pretty much it. The results were great and if I had the opportunity to, I would have bought the 605CC over the 533MC, but unfortunately, it wasn’t yet released when I got my first astrocam.

To test this, I piggybacked my Askar 71F with the ASI533MC Pro on top of the loaner Svbony SV550 Triplet with the SV605CC. This is what it looked like:

Let’s take a look and compare images of M3 and M13 taken with both of these astro cams on the same night.

On the left, we have the ASI533MC Pro and on the right we have the SV605CC. M13 on top and M3 on the bottom. Which do you like more?

Smart Telescope Script Update – Officially in Siril!

By Naztronomy • Posted on 6/23/2025 • Updated on 7/2/2025

I’m happy to announce that my Smart Telescope Preprocessing Script in Siril is now officially in the Siril Scripts repository. Which means that you can easily grab it from the Siril’s “Get Scripts” menu without having to go to GitHub.

Watch the video above to see how to update it and the new look of the script. At the time of this post, I have also included an Autocrop functionality that calls upon another script in Siril. It’s still in beta but the version should be 1.0.1.

Siril Python Script for Smart Telescope Preprocessing

By Naztronomy • Posted on 5/29/2025 • Updated on 5/31/2025

The next step of the Siril Preprocessing Script is live! This time it’s in Python format and it gives you a LOT more control over how you want your data stacked.

I highly recommend watching the video above. And when you are ready, get the script from my github here: https://github.com/naztronaut/siril-scripts

Have suggestions or comments? Let me know in the video’s comments section or create a new issue on github.
