A Planetary Nebula (Sh2-188) and a Check (Astrophotography)
Ғылым және технология
Sh2-188 is a faint, but interesting looking planetary nebula. It lies in Cassiopeia, a little more than 700 light years away. It is estimated to be around 7,500 years old.

Great video and thank you for continuing to put out quality, informative clips. I posted a question after your unboxing of the EQ6R Pro asking how it performed and could you recommend it. You wanted some run time before you provided your opinion. I have been following all your videos since and it seems to be behaving well. Could you comment now? Also, could you compare and contrast your CGX and the EQ6? I am still trying to weigh as many factors as I can before I take the leap and buy a mount. Thank you again and please keep up the great work.

Thanks Christopher, after using the EQ6-R Pro, I really like it. It guides well, it has never failed on a meridian flip. My CGX has failed the meridian flip many times with an RA Switch Fail or Dec Switch Fail (the mount needs to be powered on and off when this happens). My CGX has needed maintenance in the past. Maybe my EQ6-R will need maintenance in the future, but time will tell. But after almost three years, I'm still using the CGX. The EQ6-R mount handles a smaller payload though, so if you have a big scope - you might need a mount that is more heavy duty.

@@ChucksAstrophotography Thank you for the feedback. Informative as always. I have a vintage Celestron 8" SCT-SE and no astrophotography gear yet. I am thinking the EQ6-R Pro will have enough muscle. Interesting comment about never buying another Celestron. I have been reading and watching as many reviews as I can find and I have been getting the feeling Celestron might not be quite up to par. Going to take the plunge into this moneypit of a hobby called astrophotography as a Christmas and BDay gift to myself so I will be making a decision soon. Thank you again for all the time you put into your videos and in replying to folks. It is truly helpful. Take care.

Nice image Chuck! Many congrats on getting published again and for the windfall! Doesn't the infrared on the security camera interfere with your capturing? Just curious..obviously it doesn't looking at your results, the reason I'm asking is I have a security camera looking at my Rolloff shed and was wondering if there is infrared light impact from this security camera that could bleed over to my imaging run? Thanks in advance. You out takes cracked me up yet again.

Windfall, lol. My cam is so small and far away from my scopes, that I don't see how it could possibly make a difference. The only way to prove there is an impact is for someone to capture some subs and show a with-and-without night cam comparison. My cam is nothing compared to the fog lights my neighbors have turned on in their backyards. Thanks peeb.

The reason I ask is I am having LP problems big times and trying to problem solve on how to control it, I have another Cam, call this Cam B, pointing down the side of my house toward my obs, the cam at the back of the house call this Cam A also points at my obs, (Like an "L" shape) when looking at Cam B via the software, the IR coming from Cam A lights up the whole area and was wondering if my scope camera was picking this up as well, just curious that's all. When I seen your set up I had to ask the question. My alternative now is to turn off the IR for Cam A before an imaging run to see if this helps, also I need something to take out the street lights that's causing the problem initially as well! LOL!

Gorgeous image, Chuck. It's an unusual one. Almost looks hairy! Can I ask, does the ir emitters on your cloud cam interfere with your imaging? I was going to set up a similar night cam, but somone told me on a forum it might affect my imaging. Certainly doesn't look like it's bothering your data.

Hey Chuck, Do you use 1.25" filters? They say on ZWO's site that there is no vignetting up to F5.0. Does that mean that 1.25s are okay with f7.5? Not quite sure what "up to" means; less than f5 ie. f7.5 or more than f5 at say f2.8.
