Dear Group,
I am going to use the kodak Elite Chrome 200 slide film for some long exposures of m42. As a first timer, I need some advice on:

length of exposure? I plan on stacking the scanned TIFs.
where should I get it developed?

I am using a Orion 80ED with a Canon EOS at prime focus. f/r is 1/7.5. I am guiding this with a LPI on a APEX 127 through Autostar.

with kind regards,

Lawrence

I have a problem with a commercial sponser. They did not respond to my repeated requests for price and photo. I have no way of rating this sponser. This is in response to an ad placed on astromart classifieds.

What should I do?

I found this on the outlet site:

Is this mount for real? does anybody have any feedback on the relatively fast optics for this 16" beast. can you do astrophotography with this?

with kind regards,

I have been looking at the prices for Coronado H-alpha solar filters...truely astronomical .

My budget won't hack that, but can I use a baader film filter on the front of my ED80, with a H-alpha filter on the eyepiece to get the same effect?

with kind regards,

I just found Mike Covington's nifty little program, and it indicates that 6 minutes is sufficient for my little scope, elitechrome200, and for m42.

For all who don't know the link, here it is:

I'm going to try the local photo lab to get this (they usually will give a cd with tif files as well as the slides).

Can I rate them here, or would that be un-astromarty?
with kind regards,

I have finally gotten a response from the vendor by email. They did in fact get my email. The problem was that this was an advertisement which included the phrase "or best offer", and included an offer to send a photograph by email.

According to the vendor, they never sent out a photo, nor did they legitemately consider "best offer's". They sold the advertised product within five minutes of placing the ad, so the vendor had no intention of accepting best offers. I would have paid more than the asking price if given the chance.

Fairness is often in the eye of the beholder.
