Re: pin-holes in Baader AstroSolar filters

Posted By Robert Watters

I would redo it, the black marker trick does nothing to block the IR and UV rays (not that much will be gettting thru anyway). Are you sure it is the Baader material? The reason I ask is it usually does not develop the pin holes that the other similar types do.

If you do decide to redo it make sure you don't stretch this material at all, just get it to be as wrinkle free as posible. Some light, loose wrinkles are fine.

For those of you that think the wrinkles don't matter you might want to take a look at this.

M42

Posted By Robert Watters

I finally got to try my new 6.3 R/C out after having it for better than a month now. Took a couple of shots from the back yard, not too bad considering the light polution.

Here it is, a single 15 minute shot of M42 with a C8 and the new 6.3 R/C on Kodak PJ-400. It has been cropped after the vignetting was removed (not centered!) and slight tweeks to the curves and levels in PhotoShop.

Let me know what you think.

M42-Rework

Posted By Robert Watters

I decided to post another version of my M42 after seeing how dark it looks after I posted it. The original on my screen doesn't look that dark so here it is lightened up a bit.

CCD vs Film and resolution?

Posted By Robert Watters

I keep hearing this statement from several different sources: "CCD's have a ways to go before they match the resolution of film".

Is this statement accurite? I find it hard to believe with all the CCD pitures that I have seen posted all over the web and here by out resident pro's that this is true. Some of the best shots I have seen have been taken with CCD. The film equivelents don't seem to be close at all. The only thing the film seems to have an edge with is the wide field stuff and even then I've seen some wide field CCD pictures stitched together that have much better contrast, detail and color.


So what gives? Let me know what everyone's opinions are on this matter.

M45

Posted By Robert Watters

This is a shot from a couple of months ago that I just had developed.

It was so long ago I'm having trouble remembering the details. :-)

2 x 40 minutes with a ST-80 F5 refractor on Kodak PJ400 film. Slight tweak on the curves and levels in PhotoShop.

Comments appreciated,

IC410/405/417

Posted By Robert Watters

This is a shot I took a couple of months ago but it has been stuck in the camera untill just recently. IC410 is centered in the pic with IC405 (Flaming Star) on the right. IC417 is at the top centered. M36 is just out of view at the top left.

Shot thru a ST-80 F5 (400mm) refractor and is two 40min. shots stacked with Kodak PJ400. One of the shots was trailed a bit so it's not as sharp as it could be.


Comments appreciated,

Digi-Scope Camera?

Posted By Robert Watters

Well, I'm thinking about taking the plung into the digital realm. Right now I'm leaning towards the 4MegaPixel Cannon Powershot G2. It has a 52mm threaded adapter for accessories like macro and telephoto add on lenses. I want to stay in the $450 range.

Was wondering what some of you guys use for digi-scoping.
Are there any makes and models that really have an advantage over the others for digi-scoping?


Thanks,
Robert.

Mother Robin

Posted By Robert Watters

I know, add another Robin pic to the list. But I just had to test out my new Canon Powershot G3 and she was the only prey (I mean subject) around. She was doing her best to stay put because of the 3 eggs she is sitting on. Thankfully I didn't scare her off.

Shot in full auto mode which equaled 1/125 at F4.
