Yes, the bigger the scope the bigger the transport problem.

1. Buy a station-wagon.

2. If you know someone else interested in peering through your scope, use their car.

3. Borrow a bigger car on viewing trips.

4. Last resort - use a trailer (not recommended).

For transporting the OTA, consider the padded bag option ... I did this for my GSO 10"
It works a treat & means I can carry the OTA & the base at the same time.

I like option No. 2, but people I know, who would be interested, also drive hatchbacks. For me it's too soon to be thinking about going bigger. I'm sure there is lots of interesting things my new 8" Dob can show me. It should keep me busy for quite a while.

There is also the possibility of an excellent product called a 'Roof Boot'.

It's amazing how much will fit in them. The only problem some people have is reaching high enough to load/unload one.

After a long wait, we had clear skies for one night over Victoria last night. So I took today off and spent last night with my Dob near 90 mile beach. Just got back.

Had an awesome time! Thanks to all who responded on this thread for helping me get started.

This is what I managed to find:

Omega Centauri & 47 Tucanae I already checked out from my back yard. Much better this time without the light pollution. ditto m42. Dark skies really up the wow factor for these objects!

Things I saw for the first time:

Eta carina & tarantula nebula. Not only these objects themselves but also the areas of the sky they're in are astonishing. I spent ages looking at and around these two.

ngc5128 -- yes Andrew, I saw the hamburger!
m83 --- core clearly stands out, but no structure (no hint of spiral arms)
m104 --- faint but there, not much structure
n3918 --- blue planetary did show hint of blue, but maybe I imagined it because it was very faint. I lost it when I upped the magnification.

I looked and looked for ngc3132 but could not find it. Maybe it's too faint.

By the end of the night I got much better at star hopping. Initially I found it really difficult, because the scope shows so many more stars than the charts I printed do (with all stars to mag 10). Eventually, I worked out thja I could rehearse the star-hop journey from a bright star to target with the binos before attempting it with the Dob. The $26 I spent on a 2nd hand 7x50 was well worth it. (The Andrews 10x32 "bonus" binos are not so useful. Too much magn., too little aperture.)

Finally, Jupiter was the best I've ever seen it. At 300x it was just starting to show a little atmospheric shimmer. Really need tracking at 300x though. Saw the GRS for the first time this morning.

Was out till 5:30am. The thought of sleep had not crossed my mind all night. It hit me after I packed up and started driving. I had to struggle to keep my eyes open to make it back to my accommodation some 5kms from the site. Slept till early a/noon.

Well done Janos.

Isn't it amazing what you can see from a dark site.

You certainly whittled away on your 'search for' list.

I got fogged in again last night at 2:00a.m. so had to give it away.
You certainly had a long night to take it all in.

Hope you can get to 90 mile beach often.

Enjoy!

Janos

nice to see you got away to some dark skies and found the ghostly hamburger. You mentioned that you had trouble finding n3132 (Eight Burst Nebula). Your 8" should easily be able to see it, but I guess you have to know what to look for. When you look directly at this planetary it will appear starlike (ie the star imposed near the central star dominates the view). When you look just away from it to a neighbouring star you will notice (with averted vision) a haze / fuzz around the target - almost like it is out of focus. Did you have a detailled enough star chart when you hunted it down? If not, get into some planetarium software like CdC and make your own finder charts.

Also, recently I have found that using high powers can help with planetary nebula. Infact when you hunt for this I would suggest starting at around 70 to 100x magnification to help it stand out from stars. Do you have a UHC / OIII as this will also help in identifying the planetary (using the blinking method)?

regards

Andrew

Janos, I don't know if you have any star charts or atlas's. IMO, the Herald-Bobroff is the best Astro Atlas (about $100.00). Sky Atlas 2000 is pretty good.(loose leaf). An excellent ref. book is Hartungs Astro obs. for Southern T'scopes ($80.00). (bit light on, but O.K.). Burnhams lot more detail ,but there's 3 editions.(southern hemi).
Orion area from H.B.AA.
ps. Black stars on white.(not enough light).

Thanks for the tips re finding n3132. I used two charts to help me navigate:

http://members.optusnet.com.au/~jano...-nav-small.jpg

The top one is an overview with all stars to mag 6.5 and ngc3132 near the top right corner. The bottom one is a zoom-in on target with stars down to mag 10. The circle is 5 degrees in diameter.

Don't have any filters and I'm missing out on the mid range magnifications. I have 7 Ploessls but still nothing between 10 and 20mm. (Andrews was out of stock of 15mm when I ordered the Dob.)

Do you have a barlow? If not, that'd be my next must-buy item, it'll give you all the mid-range mags you need.
