Comet C/2023 H2 (Lemmon) - Has anyone seen it?

#1

Post by StarBru »

Last night, I came home from a 10 hour workday and was determined to get a glimpse of Comet C/2023 H2 (Lemmon). I looked up its position in Stellarium. It was in the constellation Aquila. So even though I saw clouds moving in, just after the sun set and it was getting dark, I set up my Meade ST-80mm f/5 on the Twilight II mount and waited. It was supposed to be around magnitude 6.7, so I thought no problem!
:confusion-shrug:

While I waited, I swung the scope toward Saturn and looked at it for awhile with a 6.5mm, and then a 4.5mm eyepiece and enjoyed a much sharper image of Saturn than I had seen through this telescope a few Saturdays ago, so the seeing must have been somewhat good. When I thought it was dark enough, I aimed my scope with a 25mm eyepiece toward Altair. The clouds were really getting close now. I then star-hopped east to the star Beta Aquilae (Alshain), then southeast to Eta Aquilae, then northeast to Theta Aquilae, then turned my scope south and east to where I believed the comet was located, but I just couldn't find it. I had to wait while a few clouds passed, and then I scanned the whole area between the constellation Capricornus and Aquila north, south, east, and west between the two constellations. Didn't matter, no comet, and more clouds!
:Astronomer1:

I took a break to eat dinner, hoping the clouds would go away. After dinner, more clouds! I scanned the area south of Theta Aquilae and east of Eta Aquilae again where the comet should be, but no comet and now too many clouds. I scanned the area back and forth, but no comet. As Aquila would soon be too low to the horizon and the clouds were ever thicker, I decided to call it quits for the night.

Tonight the comet has moved into Capricornus but there are just too many clouds, so no comet hunting tonight. Has anyone seen this comet?! :?

I haven't, but I also haven't been looking. I hope someone get an image of it.

A good effort Bruce.
Hopefully another opportunity will happen soon.
Here it is trying to decide if it will rain or snow so no viewing happening.

Have not seen it. I fortunately I was able to catch the comet of last January/February one evening in Ursa Minor with the 102 mm frac. It had a greenish glow and slight hint of a visible tail. Will have to try for this one!

Unfortunately, Aql and friends are behind the Big Blue Spruce by the time I'd be able to observe. :handgestures-thumbdown:
I'd have to head to a dark site or something with a more open SW sky.

That's great you that you saw it! I figured it must have been fainter than predicted. Unfortunately, I missed it on Nov. 10th when my sky was perfectly clear and it was supposed to be closest to us at a magnitude of 6.4. I'm just now getting better from my virus and I just wasn't feeling well enough on the 10th. It's supposed to be cloudy here until Saturday. I'm planning some comet hunting then (still in my backyard) with some of my bigger scopes. We shall see!

It's ideally situated for me to be able to frame it up from my backyard. I've currently got the mono camera on my E.S.152 but I'll give it a shot the next clear night we have here in Vegas. I'm sure it will not be ideal conditions with my light pollution here but I will attempt it.
