BYEOS in planetary mode: EOS 1000D vs webcam

[Vox45]

Hi all,

I see in BYEOS that there is a 'planetary' mode. I own a 1000D ... how does that compare to a webcam? Do I still need to buy a webcam to do planetary or simply use my Canon in planetary mode ?

Yikes ! 18 views and no replies... Either it's a really stupid question (could very be) or a complicated topic ...

Anyone ?

The only issue with running a DSLR in this mode with BYEOS is that the frame rate will be quite low compared to a dedicated webcam etc when i tried it i could only manage 6-9 fps so could be missing those rare frames when the "seeing is perfect".

The only DSLR that i know of that can run in true crop mode is the canon 60D

I knew that my master plan was too good to be true... Back to the webcam then.

Thanks for taking the time to answer.

Just be aware that some webcams max out at 10fps anyway.

TSED70Q, iOptron Smart EQ pro, ASI-120MM, Finepix S5 pro.

As Alan says, the 60D runs at 60fps in true movie crop mode (by itself!). I got mine as refurbished so i was pleased with the price i paid.

I own a 1000D and from wikipedia I got this: "3 fps for 514 JPEG frames or 1.5 fps for 5 RAW frames"

darn !

Any webcam (I hear Phillips are the best) you guys would recommend ? Or should I go with something like an Orion StarShoot from the get go ?

Don't feel you can't have a play with a dslr. I got this with an 1100d, not great but we can all see its mars

Well if I can get the same result I'd be satisfied. I am a beginner and I don't put the bar too high. What you just showed here is way above what I expect, so cheers to you for giving me hope

Thanks

I agree with Scott dont be put off giving the DSLR a try i even had a go a Jupiter myself with my 400mm fl scope and camera.

Don't think DSLR are not capable of excellent planetary imaging.  Jerry Lodriguss has an entire book on that subject alone (see here).

Most DSLR will give about 20 to 25 fps when connected to a computer, except the T4i which is not capable of more than 10 fps.  If you get less that those numbers in means your computer is the bottleneck, not the camera.

When doing computer assisted planetary imaging with a DSLR you need to make sure you are using live view 5x zoom mode.  This will give you a 1:1 pixel resolution and the best quality.

Hope this helps,

Here are my Mars and Jupiter from my first try at using my 1100D for planetary, using APT. From memory I was getting about 13fps.

This was with a 12" newt and 4x barlow though. Next time I'll try a webcam and see if that works better.

I believe the Canon 600D has a 3x crop mode using the centre of the sensor, according to Cheap Astrophotography.

Nice pics Knight

Thanks for the tip Guylain I will give it a try !
