Canon EOS D60

Posted By Joe Bruessow

I am wondering if any of you have heard anything about the new Canon EOS D60 35mm format digital camera? The review on the following link shows a 4 minute exposure with virtually no noise! Huge array, 35mm format, can be used for everyday and astro use... hmmm.. sounds promising! Your thoughts... Maybe astrophotography/ ccd imaging will take another turn... I have heard rumbings on tech tv about a new chip perhaps this is it?

The scope has a built in barlow... I had one that I bought for fun a year or so ago and it wasn't bad for the $$$ spent... may I ask what you have observed or specific impressions you have had? ... What sort of 12" scope are you getting now?

My first pics...

Posted By Joe Bruessow

Well, I have taken the plunge into CCD imaging. I've been into visual astronomy for many years but have always been intrigued by CCD's. I have had a 12" LX200 for a few years and finally decided to give imaging a try. Last winter I purchased a $50 webcam and got some great images of the gas giants. Then I bought Ron Wodaski's book and realized that I am now knowledgeable enough about this technology to give it a try.

So, this past month I sold a couple of small scopes and bought a used ST7 non-E imager and a used Optec Maxfield f/3.3 reducer. This seems like a pretty good beginner set up with the equipment I have. I have attached the first of my images which is a 4 minute unguided exposure of NGC 891 I took last night (through a #8 yellow filter to reduce chromatic abberation introduced by the reducer). I want to learn how to get a respectable black and white image before even considering looking ahead to LRGB. Your tips for how to enhance this image would be greatly appreciated.

Second, a technical problem with my camera/ software (CCDsoft version 5). I can take fine unguided pics with the main CCD... but when I attempt to image with the guider chip in order to callibrate and autoguide the shutter does not appear to stay open. If I set the exposure to say 10 seconds the shutter dialogue box in CCD soft shows the shutter opening for perhaps a tenth of a second then shows it closed for the rest of the exposure and the resulting image looks like a dark frame with hot pixels. Any ideas as to what I am doing wrong? I do click/ select the guider chip before the exposure... but am I supposed to do something else? Thanks!

Technical problem...

Posted By Joe Bruessow

Some of you may not have read my previous post about my first pics but at the end it asks about a potential problem with my camera (ST7) / software (CCDsoft version 5). I can take fine unguided pics with the main CCD... but when I attempt to image with the guider chip in order to callibrate and autoguide the shutter does not appear to stay open. If I set the exposure to say 10 seconds the shutter dialogue box in CCDsoft shows the shutter opening for perhaps a tenth of a second then shows it closed for the rest of the exposure and the resulting image looks like a dark frame with hot pixels.

Best CCD mount for under $3,000

Posted By Joe Bruessow

I am thinking of getting a quality short focus newt. (approx. 10" to 12"), a C 9 1/4", or a Mak-Cass or Mak-Newt. in the 8" range for ccd and visual work. I'd like to hear recommendations on a mount. I know of several mounts but would like info from actual users. I wish the Williams Optics GT1 was still available but that appears to be gone? BTW... I was going to get a Meade LX200 GPS... and still may, but I want to look at all of my options... quality of photons is becomming more important than quantity as time goes on. Thanks

Telescopics Newtonian Primary Mirrors

Posted By Joe Bruessow

Anyone have any ideas as to the quality of Telescopics mirrors? Any first hand experience?
Thanks!

Saturn 2/28/03

Posted By Joe Bruessow

Not too good... but considering how bad seeing has been here in Michigan, I'll take it. 12"LX200 at f/18.

MI 250 Mount Thoughts...

Posted By Joe Bruessow

I am considering one of these mounts for a 12.5" f/4.5 RF Royce Newtonian or a C14. Any thoughts on the tracking of this mount for CCD work with the proposed combos? Goto or older non goto version.

Thanks!

Which would you keep?

Posted By Joe Bruessow

I have quite a dilemma... I have a 10" f/6 Zambuto dob but have just come into a 16" f/5 Intermountain Optics primary which could also be made into a fine dobsonian. I love planets and deep sky. Which would you pick and why? I can only keep one... as well as a C14, and a couple of small refractors, and...

I know... aknowledging you have a problem is the first step in the healing process.

Thanks guys...
