Hi Guys,
Just a quick question primarily about thermals and visible heatwaves. I set my scope up this morning as the sun finally made an appearance to look out from my bedroom into the back garden (I opened the window first). It was a frosty morning and I was hoping I would avoid any thermal interference. Alas I was still seeing it. I am waiting for a better carbon fibre tripod to arrive this week so hopefully that will reduce the vibrations a bit but I think what I am seeing is probably normal. I just didn’t expect to see it in colder weather (it was -1 this morning)
I have made a video of what it looks like (it’s not quite as bad as the video makes out as the image is sharper through the eyepiece but it gives a good indication of the effect I see though the eyepiece too).
This little camera was about 80-90 or so meters away with the scope is set to 60x zoom and I thought it would be a good test sample to demonstrate what I am seeing. The reason I ask the question of is this a normal effect is because I have owned reasonably long camera lenses in the past (although not as long as this scope (I think 25x is about 1250mm) and I have never detected this in and out of focus effect.
This video is quite heavily cropped but hopefully you can see what I mean.
