Optolong L-Pro filter review

Optolong L-Pro Filter Review

|Star Clusters|5 Comments

I’ve recently had a chance to review the Optolong L-Pro filter (2 types) for astrophotography from my light polluted backyard in the city. Unlike many of the filters I used in the past, the L-Pro is suitable for both stock and astro-modified DSLR cameras. (It includes a UV/IR block). I've always had trouble collecting images with an accurate representation of star color when imaging from the city. It's something I spend a lot of time correcting during the image-processing stage of my projects. My hope is that the Optolong L-Pro filter lives up to its description of allowing more starlight…

telescope mount for astrophotography

The Foundation of Every Great Deep Sky Astrophotography Rig

Over the past 8 years, I’ve had the pleasure of using a number of telescope mounts for astrophotography. Some of them were substantial imaging platforms that included features such as autoguiding and periodic error correction (PEC), while others simply tracked the night sky at sidereal rate in a compact and portable package.

Don't get me wrong, dedicated astronomy cameras and heavy duty mounts are great, but my latest imaging session in the backyard was a breath of fresh air. In this post, I’ll share my early results with a new compact refractor telescope, the William Optics Zenithstar 73 APO.  I’ve managed to collect some exposure time on a number of deep sky objects using a crop-sensor (modified) DSLR. My experiences with the Z73 have reminded me how much I enjoy deep sky imaging throu…
