Astrophotography is…

Expensive Time Consuming Frustrating Steep Learning Curve

Page 10: Ed Ting Lowbrow June 15, 2012. Astrophotography is… Expensive Time Consuming Frustrating Steep Learning Curve.

Inexpensive (Relatively) easy Fun

Page 11: Ed Ting Lowbrow June 15, 2012. Astrophotography is… Expensive Time Consuming Frustrating Steep Learning Curve.

Video is just a series of stills run together.

If you take enough stills, some of them are bound to catch moments of good seeing.

We have software (Registax) that will throw away the images in bad seeing, and keep the good ones.

Stacking the good ones brings out detail in the images.

C90 Image from 2011

The lowly computer webcam. Philips ToUcam (L), SPC900NC (R)

Page 14: Ed Ting Lowbrow June 15, 2012. Astrophotography is… Expensive Time Consuming Frustrating Steep Learning Curve.

Resolution is low (640 X 480) One shot color reduces this even

further Some rows of pixels are masked off,

reducing pixel count even more Jupiter will not even come close to

filling the chip (200 pixels across is excellent)

1 Gb of video one image 7K – 50K

Page 15: Ed Ting Lowbrow June 15, 2012. Astrophotography is… Expensive Time Consuming Frustrating Steep Learning Curve.

Some of the best planetary images EVER have been taken with this method.

A modified Philips ToUcam $129 list, about $100 street Uses the Sony ICX098QB chip,

640X480, ¼”

Page 17: Ed Ting Lowbrow June 15, 2012. Astrophotography is… Expensive Time Consuming Frustrating Steep Learning Curve.

$350 - $810 depending on model Uses the Sony ICX098QB chip, 640X480, ¼”

Page 18: Ed Ting Lowbrow June 15, 2012. Astrophotography is… Expensive Time Consuming Frustrating Steep Learning Curve.

$800 - $1000 Flea uses the 4X more sensitive Sony ICX618 chip

Webcam (NexImage, ToUcam, etc) Telescope with 1.25” focuser Laptop running 1) Capture software,

2) Registax (both are FREE) LOTS of hard drive space

4000 mm to 4500 mm is ideal

8” f/10 SCT with a 2X barlow 4” f/8 refractor with a 5 X barlow 6” f/8 reflector with a 3X barlow 80 mm f/6 refractor with 3X and

2.5X barlow stacked

Start collecting barlows!

Step 1 – Sorting through individual frames

Page 30: Ed Ting Lowbrow June 15, 2012. Astrophotography is… Expensive Time Consuming Frustrating Steep Learning Curve.

Step 2 – Align the good frames

Start with the moon Venus is easy but not terribly

interesting Jupiter is the next easiest Saturn is a little more difficult Mars is not easy Uranus is hard
