Whether you’re an amateur astronomer seeking to upgrade your telescope setup or an experienced astrophotographer needing a lot more precision, the Skywatcher Wave150i Harmonic Mount is designed to meet your needs. This blog introduces you to the Skywatcher Wave 150i Harmonic Mount’s key features and explains why it’s a standout in its class. Please note: […]
If you have a telescope and want to enhance your night-time observations, there are tools and techniques you can use. One approach involves using Astronomy filters, which are important accessories that can isolate specific wavelengths of light. This helps to reveal fainter deep-sky objects with greater clarity. Filters come in various sizes and mounting options […]
For long exposure astrophotography of Deep-Sky Objects, autoguiding is a must. Read our guide to learn what Autoguiding is, and why you need to do it.
Read our review of the Optolong L-Ultimate Filter – a 2-inch Filter designed for Colour CMOS Astronomy Cameras that makes light-polluted, narrowband astrophotography a breeze.
After using many different types of light pollution filters – one filter that stands out the most is the L’eXtreme filter by Optolong.This filter boasts a 7nm range in the Ha (hydrogen) and Oii (oxygen) bands, which is comparable to dedicated narrowband filters – that offer 7nm. The L’eXtreme filter allows me to photograph deep-sky […]
I will show you what can be done without too much effort using a One Shot Colour Camera (in this case a ZWO ASI294MC Pro) and the Live Stacking feature of the ZWO ASIAIR Plus. The filter I used was the Optolong Le’Nhance filter (which captures LRGB plus some narrowband emissions all in the one […]

Hi, my name is Gerald and I am the Sales Specialist at Optics Central.My speciality is telescope configuration and astrophotography. I am a graphic designer and photographer by trade and have 8 years experience in astrophotography. I started […]
This is part 3 of my series on astrophotography with filters. Last time I explained how the human eye sees in colour, using three different types of cone cells. We use one type for sensing red light, one for green light and one for blue light. The different channels are then recombined in our brains […]
This is part 2 of a series of blogs about filters and narrowband astrophotography. Bill explains how filters work, why you might use different filters and what a photo taken through a filter looks like. In the previous blog, I went into a bit of my own history: how from DSLR photography, I gradually moved […]
This is part 1 of a series of blogs about narrowband photography. In this introduction part, Bill talks about how – and why – he moved from taking astrophotographs with a plain DSLR to a monochrome CMOS camera with filters. It’s all about how you want the hobby to develop Astrophotographers aren’t normally wealthy people. […]
