Is that your giant Cassegrain in the video? I like really wide field astronomy, gathering as much light as possible--no mirrors. I have refractors, and those pretty new little shorty Vixen wide angle binoculars that look like opera glasses. But I've thought a lot about getting a smaller Mak recently, maybe something under 200mm--Vixen, like their 110.

It been cloudy the whole damn time so far in Nor Ca. So I've had no chance in seeing it this time.

Thanks for the post.

wide field astronomy? yes and no.
it's moving so incred fast, that you risk blurrs, so you have to correct for the right galactical axis, and the speed of the comet. and test # frames taken/ sec.
Notice: 20 years ago they had to correct this manually, frame per frame, to make a realistic video of 3 minutes.

see more info the video's of the 2nd author.

Comet C/2018 Y1 (Iwamoto)

This 1 is a once in a lifetime experience:
It is only discovered a few months ago, because its fartest distance from the sun is ... the fartest distance Pluto ever reaches away from the sun, and this distance multiplied by 6.
And it is already returning back to the Kuiper belt.

also it's now in the constellation of Leo, and moving to the right.
