Neil,
You'll find that magnitude numbers are highly deceptive when observing galaxies. The magnitude is a measure of the total light arriving from the object. If the object has a large apparent area (M 33) it will look relatively faint, while a more compact target (M 82) will appear much sharper. Surface brightness is a much better indicator of how an extended target will appear.

I have not used any type of imager , but I have had problems with not enough out travel , so I use a 2" extension tube. The Moonlite on my refractor must have over 4" of travel and is so easy too focus. I had planed to use the MCHP on my C6-R , because of the go-to functions of the Atlas, but will try an use the 12" LB and my Telrad and SV finder with it's illuminated eyepiece. I can locate most familiar M objects and larger NGC, it's the faint fussies, that I would like to use a go-to drive to help locate these objects. I'm concerned about being able to focus with a 9" monitor and yet not destroy my or other peoples night vision. I really don't want to have to add a 4" monitor to my scope, it already has balancing problems. See my counter weight system for my LB.

Bill


Try remounting counterweight system 180 degrees. Your problem is having all the weight on one side of the tube so at zenith it wants to tip backwards. Equalize the radial weight and everything will work good.

Point taken, but there must be a general rule of thumb for at least starting out whith the setting for the camera, and how long of an integration time is required for bringing out detail without burning out the image. I know this will not only change from object to object, but from scope to scope as well. I'm just looking for some one to let me know what settings they use. Even if it's just an example of a specific object, I could at least have a jumping off point, and adjust from there. This, like I said, could help a lot of people here at least start close to what they will end up using.

Add NGC 891 to your target list. It's a ghostly looking distant edge-on galaxy in a bright star field.

If you haven't seen it yet, you'll love it!
This is exactly how it looks on my monitor, using the 28" StarStructure.

My Round table platform is in town, out for delevery tomorow. I will be looking for sucker holes, for the next few days, and Thursday looks like it's on for about 3 days of clear skies, into the weekend! I know it's just Sunday, but I belive in positive thinking!

All right everyone, my Round Table Platform just showed up here at my work! :jump: :waytogo: :gve: :bounce: :flexible: :whee: :drool5: :yay: All I can say is, WOW! This thing is very sharp looking. It's a little heavier than I thought too. I'm really glad that I went with the larger 28" platform. I can tell that it's going to be very stable with the Orion. The only thing I wish it had is a more in depth manual. I'm sure I'll be able to figure everything out, but there could be more explanations giving how important it is to use it correctly.

The craftsmanship is top shelf! I'm at work right now, as I stated, but when I get home today I'll post some pictures.

I can't wait for first light with this thing. Now I can really see what my Mallincam can do! Of coarse it's cloudy today, and tomorrow, and Wednesday, but Thursday through Sunday look GREAT!!!

By the way, keep feeding me targets, if you think of any I haven't listed.

Neil

Thanks guys! I'm really happy with it.

I need to figure out what type of non-slip surface to put on it, so my scope doesn't fall off :bigshock:

To all the round table owners out there, how did you attack this problem? Brian does send you 3 grip squares that you can attach to the table, but is there a better choice? We are talking about the cost of the stuff on top of the table being at risk!!! I can see how the grip tape would prevent an accident, but if there is something you guys are using, please let me know. Pictures are also helpful!

Clear enough skies!

You know that "no skid" rubbery stuff they sell for putting in drawers might be just the trick...

So far, Neil, I'm just using the skid pad stuff that Brian included - seems to work just fine... at some point I may work up some sort of "jig"... but between bad weather and family medical stuff the last few weeks, I've not gotten out once in 2 weeks!

Glad your RTP finally arrived!

Thanks for chiming in Dave. Sorry to hear about the hectic last couple of weeks. I hope things get better soon!

I went ahead and used the three squares that Brian included. After testing it, the scope didn't slip a bit. I'm actually doing a test run right now to make sure that all is well. I'll have pictures up in about 50 minutes at the end of the platforms travel.

I really got to give some more props to Brian! It truly is a work of art.

Clear enough skies!

OK, this thing is awsome! Not a single worry about the stability of the scope sitting on top. It was very quiet too.

Here is the grip tape applied. I did as the instructions suggested, and put two pieces on the north runner, and one piece in the middle of the south runner.
