Hello,

 

I wanted to share my image of Jupiter with an Io transit from last night. It feels great to get  this level of detail with just 6" of aperture. No barlows were used, just the ASI178MC at prime focus and ZWO ADC. Capture in SharpCap and processing in Astra Image.

Great result, Gustavo! Which mount did you use?

An iOptron AZ Pro, the raw video lasted around two minutes, around 4,000 frames.fe93bef76c2300f822b2c8d2cf829ca0.jpg

Thanks! I am looking at this scope for my next upgrade.

I already have that mount.

If you can get Google to translate it, my blog shows all the steps it took to process the image:

Can't see it, so can't like it or judge, but I will say that you have a very nice little equipment setup. Inexpensive too, as far as decent imaging systems go.

Hey thanks; the bottom ribbon of the image details the equipment used, and post #3 of this thread contains a photo.

Very good work, and your telescope is apparently surprisingly good for planetary imaging. You also had good seeing, which is often the difference between good, and poor images. While larger apertures are preferred, your image shows how well a 6-inch telescope can work on the moon and planets.

Thanks for the comments. To be honest, my seeing was not good! Did you watch the YouTube video in the blog post (link a few posts above)? If it doesn't look that bad, is thanks to SharCap! The seeing-filtered capture feature is a game changer. It lets you weed out the bad seeing frame during capture instead of afterwards during stacking, and makes your videos a lot better than they should be with a simple capture. I assure you, my seeing is mediocre at best. This capture functionality is what is making a small scope sing for planetary (within it's capabilities of course and having an apparently good sample doesn't hurt).

The seeing here along the Gulf Coast is usually poor, or worse too. Perhaps that is the case where you are as well. I have looked at the video, but I have heard of the seeing monitor feature that you have to pay for. Seeing like this is really bad for an 8-inch F/10 SCT, even more so if a 2X Barlow is also in play. I record a lot of video, and at best use 20 percent of it, often I less well under 10 percent and discard the rest. However, smaller telescopes are not bothered as much by poor or mediocre seeing than big ones. There's been many a night where I get quite nice views through my 6-inch, but the views are a hot mess through my 15-inch. That is why I opted for an 8-inch, because I am very familiar with being unable to get anything to focus at all through my big Dob. The seeing's effects are still there in a small telescope, but the smaller image scale ensures it's hidden. Still, you got very good results by any measure. A good warm up for this year's appearance of the planets, and the coming transit of Mercury across the Sun late this year.
