A little help with imaging

Hello, I've just got my hands on a ZWO ASI120MC Colour 1/3" CMOS USB2.0 Camera.

I had a bash at Jupiter a couple of months ago using a Celestron NexImage 5MP camera and the results were rubbish and I had to send it back twice due to a fault with the camera.

Anyway fast forward to the other night and I had a go with the ZWO. I know it's now not the best time to try to capture images of Jupiter but I had a go as well as Mars.

From what I can see my images are still pants ! lol ! I've see much much better pic here !

Are the files I create using RegiStax 6 meant to be so small ? 883KB - 444KB ?

Could I get better Images if I get out of Stockport Town centre and into an area away from pollution and I don't mean light pollution just heat and rubbish in the atmosphere ?

I'm using a SkyWatcher  SKYMAX-150 PRO with the camera, and I set the limit of frames to 2500 for the AVI.

Any help would be very much appreciated .

I've attaches one picture of Jupiter and the Mars picture in my gallery for anyone to have a gander at ! LOL !

not a lot wrong with that image, if you want to make it bigger try using a 1.5 drizzle setting in registax

Thank you I will give it a try. Ive only used RegiStax a few times and I'm only just getting tio gripps with it.
Kind regards Andy

Hi Andy, that looks like an amazing shot mate.  the amount of detail especially in the more temperate zones (towards the poles) is really nice, i have not had much of a go at imaging but the little I have tried has come out quite well - all be it with a very old Toucam 840 webcam through the 11" - so in comparison a very nice image from the 150.

I've just tried to ramp up the frame rate to 60 fps on Mars - initially I was losing more frames than keeping in SharpCap, but the other night I think it was purely down to the seeing more than the actual capture as Mars was wobbling all over the place - even with the raw avi, detail was hard to focus on - it was that unsteady, also, I'm not very good with processing, but the end result was really good (to me anyway!!!)

Here's the only ones that I could post so far - I think a few more years at it and I should get a little better ( I think the Jupiter could do with more fiddling with though.)

best Jupiter 1

Thanks - Paul.

when you get to the Limit screen there is a drizzle box, tick it and set it to 1.5

or select re sample and select 1.4 - 2.0  to increase size accordingly

have used both the drizzle and resample but can't really see any difference in quality between the methods

I'm not familiar with your setup but that is a pretty good shot of Jupiter. Better than my first and most recent. 

Many thanks. At least I seem to be going in the wright direction.

I was about to give up. It's hard without any one to help guide you in the right direction.

Thanks again Regards Andy

Hi thanks for the support.  It's a tough nut to crack planetary imaging !

It's good to know I'm going in the right direction as I'm more used to photographing birds and there are lots of people I meet that can give advice.

Planetary imaging not so many ! lol. I'm the only person I know locally apart from the local telescope shop and I don't like to bother them to much.

I see so many great images here and on Youtube  I felt my meager efforts were rather poor.

Kind regards Andy

Hi Andy,

I think that is a cracker for a first few attempts. I also think that there is a lot that could be improved with processing as you gain more experience. I do not do  planetary imaging any longer but I would be very proud of that capture. On the other hand and without being condescending, producing top class planetary images such as the ones that you have probably seen here or elsewhere  takes a lot of experience, patience, and perseverance as well as top notch equipment, you already have the equipment so just learn to be patient.

Regards,

A.G

Nice 1 Andy, if you trawl through the amount of cameras that are available now and the prices you have to pay for them, it can become a very expensive part of the hobby, I've never really been too bothered about any imaging - just so happens that I had a Toucam  already and as the guys have said on this thread it takes a large amount of different things to fall into place and I think the more expensive cameras will give better results from what I  can gather and the different things being, camera chip size, better seeing conditions, high focal length, planet height above the horizon, planet size, location well above the ecliptic, high pressure and sky transparency to mention but a few - all these play a major part in getting a good set of images.

The other night, I was trying Mars for the first time this apparition, not expecting too much due to low height and a relatively small ( ~15 arcsecs) disk and with a small chip on the Toucam, the images were that unsteady that i was having trouble even focusing, but once stacked (about 6000 frames) it gave me a very soft image, once adjusted in the wavelets the detail was there and with a slight contrast and brightness adjustment produced the above image.

On the other hand, Jupiter from March was an absolute wonder - not for imaging - just sitting at the EP with the Binoviewers in, the amount of detail visually was probably one of the best nights I had for many years and I've been observing for many years now - the atmosphere was as steady as a rock - even early evening when you would expect a terrible view due to the heat leaving the ground just after sunset - the amount of detail was breathtaking, the vivid colour of the GRS and band detail will stick with me for along time to come - so amazed I just took maybe 2 avi's all of 4 minutes in length !! and just sat at the EP's for the rest of the time just astounded, so, on that night I just forgot about the imaging and settled myself for an absolute treat from THE gas giant!!

Paul.
