Jupiter 19 March

[rumples riot]

Well here is two shots that I really think are the best images. Seeing was near perfect, but focus was the real issue this time. Maybe next time.

Comments welcome.

Paul.....why didn't you get rid of the dust.......otherwise it looks good.

[rumples riot]

And the other with some noise filtered out. I can't decide which I like more. What do you think.

[rumples riot]

Sorry Tony, I don't know how to do the clone thing in PS. Got any tips. I have in the past only used the rubber stamp and cloned that way. Is there a better way?

[rumples riot]

For those interested I did not touch the colour except to reduce the blue spectrum down. I did not enhance any colours at all. This is how it came out of the toucam.

[Striker]

No need to say sorry......the image looks great.

[rumples riot]

How did you do that Tony?

[Comet Hunter]

You're starting to get some good detail Paul! Well Done. :cheers:

[rumples riot]

Here is one I took at 320 x 280 scale is smaller but much nicer shot.

[iceman]

That is a really nice shot! Well done!

[Comet Hunter]

Are these with or without your IR filter Paul?

[rumples riot]

Andrew these are without the filter. Very still seeing and collimation as close as I can get it. Meaning trying to get the airy disk even all the way round a medium mag star. Collimation is perfect for deep sky stuff and observing, just need it near perfect to get that extra definition with a SCT. Saturation set to 50%, not too high, that way you get the natural colours. No colour manipulation except to drop the blue down a little.

I always shoot at f30 too. That is why seeing and collimation are critical. At f30 with a 3x barlow (tv) the seeing has to be very good. Image scale is critical to get the barges and festoons. I can produce the smaller scale stuff all the time, just want to get the same image scale as Bird and the same definition. That is what I am working on now.

Thanks for the comments and interest.

[Comet Hunter]

Yeah I found that last night with the saturation - on the QC I had it up around 75% but needed to drop it down on the Toucam to reduce the over rich red washout look on Jupiter. I hear ya brother re: large image scale :D

I think the key to trying to get up towards Bird's level of definition for us with USB cameras using the gear we have already is preventing compression as much as possible -> using low fps, making sure captureing laptop/pc is in good health etc (defrag, minimal software installed etc) and also possibly temp control of the primary mirror/OTA would play a big part. Besides scope maintenance (tracking, collimation etc) I think thats about as much as we can do without buying new gear ..:confuse3:

[rumples riot]

Yeah like Bird said to me, getting to know the limitations of your scope and getting around them is half the battle. With collimation you start second guessing yourself and wonder if it is just right or not. I need a really clear night to get it just so. Hoping tonight will be good. I think I might go back to 5fps as most of my shots are taken at 10. this leads to loss of quality with the compression. So now the wait is on. Don't want to sell my scope because it is a good imaging platform. Great for deep sky stuff and now that it is fully rigged for it I need a couple of moonless nights to test the alignment and do some shots on the D70.

The learning curve for digital is very steep.

Nice jupiter images!

If you can control the thermal problems in and around the scope, then I'm sure you'll be on track to getting great images. If there are thermal problems then no amount of collimation, tracking etc will help.

Only when you're in thermal equilibrium can you really benefit from those other things. I spent the best part of 10 years living here in Canberra and suffering from severe thermal problems the whole time before I figured it out.

p.s. I've updated my website, drop by and have a look. feedback welcome.

nice one paul :)
rich! :)

[Comet Hunter]

Yep, I've been thinking the same recently Paul, if I did this over again I'd get just a SCT OTA + eq mount but I've come too far to now... I plan to start on my temp control project in the next week or so - if all goes to plan should be able to cool inside OTA (similar to Bird's setup - pelt.) + when in action barely warm the corrector enough to keep the dew away while trying to avoid tube currents..all managed by the laptop/PC :D

Nice Mars work there Bird, even with a Toucam! I reckon you could get a lil' bit of detail of Uranus on a good night (even if only as much as that as you got from Ganymede...:confuse2::poke::compute r::whistle::jump2::) )

[Striker]

Nice Paul...and you got a moon and shadow as well...looks great.

[Comet Hunter]

lol..cant wait till you get into imaging Tony :D

[rumples riot]

Well finally reprocessed the best avi. I think that this is so much better than previous attempts. Not as much detail, but does not look over processed.

Am I just dreaming or is this actually better than the previous attempts?

[rumples riot]

This is the scale that this above image started at for those who are interested.

[Comet Hunter]

Yep, for sure the best yet! Not overprocessed just to get the details out (but thats just me)...congrats! is this at 10fps?

[rumples riot]

Yeah 10 fps

[Comet Hunter]

As much as I hate losing overall frame count maybe try 5fps...After my initial test last night the lower fps (5) gave more detail over the more frames 10fps of the same time period....
