C means it is a capacitor. There will be a printed number on the device. Use this if you want to replace it. This part is cheap, but you will need to solder this tiny part. Can be done with a fine tipped soldering iron and a steady hand. Good luck -
That's about as grab 'n go as it gets. I like this simple setup.

I like your eyepiece cap. Btw, us that dew on the grass? That doesn't bode well.

Show us your dual scope set ups

I just wondered, why the double finder? Yes, at least a Nikon-strap man. -

I like your "view down the barrel". -
I understand the problem. If only there were calibration frames to delete trees ...

"Blobs" count as well. But I wonder why you haven't got M81 and M82 in your list? these are certainly easier than many others in your list. Cheers,

Great effort, Neil. I guess you keep us updated as you fill your checkerboard? How far south does one have to travel to have a chance to catch them all? Messier was french, so I wonder if Olly would be able to see them all from his site? BTW, I make small marks in my sky atlas whenever I spot/image an M object. Not quite as fancy as your system. Good hunting!

Even the cables are colour coordinated, BRG. But since it's a movable (kind of) rig, how do you polar align such a beast?;-) -
Nice image. There are two ways to go with this camera. One way is to use it as a standard DSO imaging camera and go for long exposure times to get more signal; or you can stack LOTS (hundreds, or more than 1000) of short exposures, and use the fact that these cameras have very low read noise. http://www.astrokraai.nl/viewimages.php?id=250&cd=7 Good luck.

I like the way you captured the dark dustlanes in M81. Great image. -

Ha filter on DSLR for moonlit nights
wimvb replied to Magnus_e's topic in Imaging - Tips, Tricks and Techniques
That's still a good image you have, with lots of detail in the nebula. I haven't tried narrowband yet, but I guess: as the moon reflects allmost all sunlight (wavelength-wise), my guess is that a narrowband filter won't work. The reflected Ha from the moon will interfere with the Ha from the object you're trying to capture. To capture the faint details of Ha-nebulae you'll still need a dark background; so, no moonlight. Just my thoughts on this. -

Nice image. Very good colours in your image. You already suggested the feedback, more lightframes and stacking.Wim sent from my mobile device

Actually, you've got mych more than just a blob. Try stretching the image some more. I bet you will see lots more detail. You managed to capture the dustlanes in M31.sent from my mobile device

Bode's Galaxies M81 and M82 Approximately 12 light frames, darks and bias, no flats Light frames 300 secs at ISO800 Equipment: Skywatcher 150P on tracking EQ3-2, Pentax K20D (without long exposure noise reduction) Stacking and processing Pixinsight 1.8 (using Richard Bloch's Youtube tutorial as a guide). Generally too few frames and darks that weren't optimized, so still a lot of noise in the final image. -
