I guesstoemated around f5... but yes... seeing is crucial if high power is craved for.

AWESOME!

Yes, definitely the IR Cut will help.... but remember that with Jupiter, seeing and transparency can make or break your image.

Most likely no one had an answer... but I'd say it's a typo.

Hello and welcome to SGL.

The 6.7mm EP should give you around 140X magnification on the 8" dob.. the size should be a OK size but a 3 or 4 mm eyepiece should give you a nice good size on the main planets.

What about large aperture binoculars on a tripod? Surely that would be a great view of M31.

Happy birthday Gina.... now everyone will always remember you birthday...

Correct

Crystal clear here too.

I can not believe that it has been 50 years, and almost as long since the last moon mission (1972)... People are not even a shadow today of what they were back then... disappointing.

Great work...

Hello All, Does anyone know if there are different Celestron 8" SCT designations, perhaps due to manufacturing dates??? I'm looking at getting another 8" SCT and basically want the most recently manufactured scope I can get... basically trying to avoid a OTA that a warehouse might have had in storage for "5 years". I came across scopes for sale labeled as Celestron C8S and another place labels them as C8A... both are Starbright XLT coated, both look the same, both have the same model numbers (91020 and 91024) both otherwise look the same and both are exactly the same price. The shop that has them labeled as C8S has a few that have the Fastar compatible secondary mirror and others that are not and I'm not sure if that the case with the C8A shop, but the images on the page show a OTA with Fastar also, Is there any difference between the C8A and C8S, and would there be any degradation of the mirror reflectivity if it was in storage for a exended time like 3 or 5 years but didnt see any light? Now I do not know if they were indeed stored for so long so just asking hypethically on this matter but the C8S/A models has me wondering whether one is a older generation than another. TIA, MG

Great shots... I agree that the view in binoculars is much nicer... I thought exactly that when looking at the total lunar eclipse last year through the binoculars and trying to photograph it.

Yeah, seen it, downunder it started no too long before moonset, but still we got a good view.

Yes, I've seen a doco demonstrating this.. the start of a collapsing accretion disc...

Mate, it's a Televue.. you'll love it..... well done on a great choice.

Excellent report of a excellent night.... those views are what we all crave....

Stargazing Moon and Bayond was on ABC TV at 20:00 local time... just finished watching it.... Stargazing Live wasn't on last year, but for the previous two years they broadcast SGLive from Coonabarabran... We needs shows like these to be produced to offset the garbage that is on TV these days....

Yes, I think it would be a good camera to start with. Ultimately you have the Imaging Source cameras, Skyris Cameras and ZWO cameras that are the premium cameras to upgrade to when you out grow the Orion.

Just a web cam type, like a toucam....

I wouldn't use an eyepiece with the barlow for imaging, not necessary unless you want a particularly large scale.... just connect you camera to the barlow, find focus and yes, tracking will help you with the capture of planetary data. To summaries the procedure, the trick is to capture as much frames as possible, like a video at 30fps, than run the video through registax, keep the best 15% and stack them, and use wavelets in Registax to increase detail for a final image... You can also use AutoStakkert to stack, but will still need Registax to show detail.

It is, but if you can find one... snap it up immediately.

Better to have and not need than need and not have.

Come on Avani, you can get closer.. I wanna see the foot prints..... HAHA But seriously, the amount of detail is staggering.
