Jupiter and Celestron C8

[astroavani]

Two pictures to demonstrate the potential of a telescope of 200mm in planetary photography.

The Facilities Policies of seeing was not good, high relative humidity associated with strong wind with a very high turbulence.

Yet the photo shows potential, then it would be possible to get a good night?

Setup: Celestron C8 + ASI 224 + L filter Astronomic

Capture of about 15,000 frames 5000 with the top stacking.

Excellent images

[northcanadian]

More beauties!!!

[Stargazer33]

Another example of how I am not making the most of my C8! Thanks Avani!!!

Great images as usual. I really, REALLY need to get back out and do some imaging.

[laudropb]

Very nice images which what can be done.

[Aussie Dave]

Another very good example of what can be achieved with an 8" SCT and a good astro imaging camera.

Avani would it be ok to use a 2x or 3x Barlow with an 8" scope? Will some sharpness in the image be lost?

[michael.h.f.wilkinson]

Very nice indeed. I tend to stack fewer images. With the ASI120MC (same pixel size as the ASI224 used here) and a 2x TeleXtender I got some decent results with the C8 last year

They are a bit noisier than the above but the detail is similar

[astroavani]

Very good job Michael, we have to take into account that you used a big resize and in this case the details tend to disperse. I'm using almost always a 2X Powermate and rarely an Tele extend 3X. In my case and because of the particularities of my seeing realized that use the Powermate yielded sharper detail, as when I use Tele extend 3X the details tend to be smoky.

Did you notice that in my capture Ganymede presented albedo spots?

I found this a fantastic thing for just a C8.

[astroavani]

Hello Aussie! You should use on a Barlow 2x or 3x as they give you a more adqequado sampling to work with a C8 at f / 20 or f / 30. Which one to use will depend on the particularities of seeing each night.

Only recommend the use of Powermate or quality Barlow proven because with them you do not lose anything sharpness in the image.

I used 1.5x drizzle. Normally I rescale those down by a factor of 1.2, but couldn't find those files quickly. Jupiter was close to opposition at the time, which helps with the size.

Hi Avani. I haven't tried my Barlows with my webcam.

I only have a standard Celestron 1.25" 2x Barlow, OPT 1.25" 3x ED Barlow and a Bintel 2" 2x ED Barlow. I don't have a Powermate yet.

Which Barlow would you recommend or should I not use any of these?

[Gazabone]

Very nice. I'm looking forward to having another go at Jupiter on my C8 with the Atik Titan I got last year

[Stephen Green]

  They are very nice images great detail

Very nice pictures.

Jupiter is my favorite. I hope to take my first pictures this year of some of the planets with my Skywatcher 127. 

[astroavani]

But should use fellow Aussie! If your Celestron is the Last I recommend using it, this Barlow along with Orion Barlow ultrascópic are long, very suitable for planetary and lunar photography. But as I do not know the other suggest test and see which will give better result.

[SnakeyJ]

Great images from your C8's Avani and Michael, excellent resolution in both.

[symesie04]

Lovely images. 5000 frame stacks? Your pc chew on that for a while. By the way I assume you mean 2000mm focal length right?

Thanks Avani, I will test them to see which Barlow works best.

[astroavani]

Hello simesie04, actually forgot to mention that I used a 2X Powermate, then the focal length of 4000mm was. My PC has HD SSD because due to high speed of ASI 224 (130 fps) a good quality machine is required.

[Pete Presland]

They really are superb images Avani. You certainly getting the most out of the C8, ASI 224 set up. How does the 224 compare to other cameras you have used?

[astroavani]

hello Pete, the great advantage of 224 is high speed it can achieve, often work with more than 200 fps. This combined with high sensitivity in the IR provide films with lower noise and thus better quality.

[Ruud]

Awesome images, Avani, and very good tips as well. Thank you!

[astroavani]

Hello Pete! The great advantage of 224 over other cameras I've had is the big catch speed combined with good sensitivity in the IR. This allows you to freeze the seeing and reduce noise.

So tempted to get a replacement for my 120mm and also with colour there will be less processing!

[knobby]

are you using a IR filter Avani,the 224 has a clear window doesn't it ?
