Optolong 7nm H-alpha filter.
Clip filter to fit canon aps-c models such as the 600d i have used this in. Image attached to show what I've been able to achieve with this filter with the 600d with my basic skills.
In excellent condition as seen in pictures.
Have found this 7nm to be far superior to the Astronomik 12nm I have used in the past. Producing higher contrast, punchier images
Have proof of purchase from 365 astronomy if required.
£115 including postage.
For sale is my Celestron SkyPortal WiFi adapter, which is pretty much brand new. I only brought it on the 4th July 2020 (photo attached). I am unable to return to Amazon so thought I would sell it to try and recoup some money.
it works perfectly and is in faultless condition, it’s just I prefer to use the hand-controller on my scope as this is what I’m personally used to.
selling for £85
