Imaging with 200P

[Stu Wilson]

After reading through the great threads on the 130pds imaging im wondering what others are achieving with the larger 200p.

Ive only got 2 months or so under my belt so after lots of advice etc and would to see everyone elses results to hopefully look forward to in the future.

My setup is 200p on a NEQ6pro Canon 650d (Unmodded) all Unguided.

Using the GOTO features BYEOS DSS and Photoshop.

Heres some of my attempts so far:-

These are really nice images.

Sounds like we are at a similar stage  I have a 200p, EQ5 and Canon 350d, again unguided. I would be interested in the exposure time and number of subs that you used for the DSOs. 

[Stu Wilson]

Most DSO are 50 lights 5 darks 90 secs exposure at 800. DSS to stack and PSP to tweak.

[Swithin StCleeve]

I'm going to sound really thick here, but what is a 200p?

[Stu Wilson]

Skywatcher 200p

[Swithin StCleeve]

Okay, thanks. It's the same telescope I have, so that's made the post all the more interesting. I'd be over the moon with those galaxy shots, (or, DSO's, as someone called them. I had to think about that one too! I'll get used to the lingo, one day).

90 second exposures on an unguided telescope and you have no discernible star trails. Crikey, i'll get small star trails with anything over 20 second exposure, simply using an unguided tripod mounted camera.....

Thanks Stu.

Did you use use any flats? The reason I ask is that I can see some vignetting in the last galaxy shot. I am no expert and am not being critical at all but adding flats to the DSS stack helped me get rid of the vignetting. I thought flats were a bit too tricky to bother with and wouldn't make a difference but I understand they are at least as equal important as darks!

Cheers

[Stu Wilson]

No i didnt use flats. Like i say new to this and big learning curve. Took me hours of messing with photoshop to start even seeing anything from my stacked images.

I took some unguided Jupiter film that was all over the place, but I ran it through Pipp (some asrto on-line imaging software) and it stabilised the image amazingly.

Im using neq6pro mount and guiding is pretty good as long as polaris setting is good.

You got a pic?

It's my very first attempt at Jupiter using a DSLR and stacking. I've got a long way to go with planetary stuff.

His mount is still motorized, tracking in Right-Ascension. But most mounts have small imperfections in their gears, which would make the stars move slightly ever so often. Guiding is using a camera to track these motions, and making the mount move in the opposite direction, correcting the "mistakes". Not having a camera do that, is unguided
Indeed if his mount wasn't moving at all, he would have trails in less than a second at this focal length.

Cracking shots btw OP.

They're lovely images. All you need now is to guide and take flats. I use the GradientXTerminator plugin in PS so I don't take flats. I find it excellent. Some would disagree!

Then it's a case of learning more techniques in processing! In PS, check the Histogram for colour balance. I alter each channel in Levels to ensure the left hand side of each peak line up. Then there's another nice plugin for PS: HLVG (Hasta La Vista Green) which removes the green tinge. GradientXTerminator also has a colour balance option which I use

Was Jupiter a still or vid?

Jupiter was a bad vid

I don't know what you did to process your Jupiter vid, but I put mine through PIPP which crops and also produces a vid file that's compatible with Autostakkert!2 which I use to stack. Then I bring the resultant TIFF into Registax for the Wavelets processing. Then to Photoshop to tweak if necessary. You can also use Castrator to crop out the black sky before stacking in Autostakkert!2. It's escellent.

Thanks for that. Ill have a look.

Just a few from me, as my 200 hasnt been used as much as it should have since i got the 135mm f2 lens:

Stu, Emyliano and U235

You have all produced some stonking images in this thread. Great inspiration for those of us just starting out at the bottom of what seems like a very long ladder.

Its great to see what a bit of perseverance can lead to ( and also the ever lengthening list of 'toys' to add to the collection :-)) )

 

[Stu Wilson]

Nice images :-)

[Stu Wilson]

Had a go last night. (Testing out different camera settings) These two images are both 4 x 240 sec subs of M51 and M101 @ ISO1600 no darks or bias just a mess around trying to figure everything out. (LIGHT POLLUTION IS REALLY BAD HERE TOO) so im thinking without a guide camera maybe stick to lots of images @800iso
