Films???

Posted By Robert Watters
Hi Don,

I think you should rephrase your question to: What film is best for astro-photography? No one film will have any advantage over the next as far as the scanner is concerned, it just scans whatever you put in it. Your results will depend on how well the film captured the object of your desire.

That being said, I've heard nothing but good praise about the Kodak E200 slide film. I think the proceedure is the same for scanning slides but I'm not 100% on that. Hypered Kodak RG200 is being used by some. If you can still find some, then Kodak PJ400 is good (but dis-continued). I and a few others have been using Fugi's NPH400 and think it does well. I think Fugi HQ or HG 400 (I'm not sure which) is doing well also. There are others but I can't think of them now.


Have fun with your new toy.

If it was RED I would be tempted :-)

Posted By Robert Watters
Me too. Pearl magenta just doesn't do it for me. :-)

Aww, what the heck, for just a couple more thousand on top of the $55,000 you can have it any color you like!!

Compuer Enhancement

Posted By Robert Watters
I've never worked with B&W yet but I would think some of the processing would be similar. CCD's shoot in B&W and I hear of people processing those shots, although I think they use specialized software for this task. It might be worth while to ask a similar question over in the CCD Forum as to what kind of processing is used and how much you can expect to gain.

I haven't heard of too many people getting those transparency adaptors for flatbeds to work very well (at least for this application), so you could probably expect to see quite a bit of improvement going to a dedicated slide and neg scanner.

OIII or Ultrablock for 9.25

Posted By Robert Watters
Hi Michael, This is a cut and paste of what I posted for Jarno in the "LPR filter light throughput" thread. It was posted in reguards to a 6" scope but you will experience similar results because I did my test with a C8.

""Jarno, I had the oppertunity to do a side by side comparison with someone elses Orion Ultrablock and my Lumicon O111. The O111 had better contrast and was a tad brighter. They do darken the back round quite a bit. I've used the UHC in the past but not side by side with the O111. From what I can remember the UHC had a brighter back round and slightly less contrast. IMHO, I think the UHC or the Skyglow would be the ones to look at for a 6" scope"".


Hope this helps in your decision.

M31 With Meteor

Posted By Robert Watters
Thanks for the comments everyone.

Hey Rick, you missed 2 outstanding nights (12th & 13th), almost the best I've seen it there at our site. It wasn't very steady but the transparency was excellent. We'll get out in the first week of Aug. or so.

Andy, the pic was done with no filters, just two 45min shots combined for the final results.

Kevin, can't wait to see your pics. Finally checked your web site out. Nice! Keep up the good work. Did you use the Tak for your shots of M31?
I took my shots on the 13th and we were seeing quite a few short, fast meteors. Alot of them seemed to originate from the Cygnus area, but there were some that came from the Perseus area so it could be an early one.

Meteor observed impacting the Moon: impossible??

Posted By Robert Watters
Video astronomers have recorded impacts on the dark side of a partial phase moon during meteor showers. I don't recall what magnification they were imaging at but all they were able to record is a small flash, no dust clouds. I doubt the dust would be seen except with a very, very large impact and only if it happened right on the edge of the disc.
Even when they crashed the moon probe (Clementine I think) into the dark side of a crater no plume was visible and there were alot of scopes observing that event.

I can't say for sure if he saw what he thought he saw or not. Highly unlikely though, unless it was a monsterous object.

Thanks for posting it Augie.

Daniel, you ought to see the enlargement he had done after some processing. This pic pales in comparison.

Don't get me wrong this is still a great pic as displayed, But to see the enlargement up close and personal is a whole different story.

Digital Camera Photography...

Posted By Robert Watters
The Nikon Coolpix 995 seems to be the top choice among many. It allows up to a 1min shot. I think this topic just came up a week or so ago in the CCD forum, look under the thread titled: "Digital camera with long exposure capability".

Sunspot (ahem) #69, 2002/8/15

Posted By Robert Watters
Because of your post I dusted off the 80mm F11 and Baader filter to take a look today. This spot is huge!! Probably the biggest I have observed this solar max. I could only make out some of the finer detail at times because of the high, thin sirrus floating through but it still was an incredible sight.

I'll be trying to keep an eye on this one for the next few days.

Thanks for the post, Robert W.
