Galaxy M101

glenc (Glen) · #1 10-06-2007, 08:15 AM

I drove 5km up to Naughtons Gap last night to look at some northern galaxies.
Saw M51, M63, M94, N4631, N4449 and M106 with 20x80 binoculars.

Also looked at them with the 12" Dob later in the night.

Tried to see M101 with 20x80 binoculars but the light pollution from Brisbane washed it out.
Brisbane is 150 km away in a straight line!!!!

I was going to set up for a lil observing last night, but beer, wallabies and
the jet stream kinda killed the idea. When I got up about 5am this morning
it appeared the jet stream had gone, which was confirmed online.

So tonight hopefully it'll stay clear.

Re: Naughtons Gap

I could hear the wind but the ridge on the south side protected me from it.

Glen M101 is just to far north for me as I have a 10deg high ridge just where it would transit.
I have observed 99 Messier objects, the 99th a long time ago.
I will have to go further North to get the whole lot.

I propose an astro camp next year inland from Cairns at the new moon in August/September. The northern Milky Way should be visible then. Is anyone interested? e.g. Mt Surprise 30/8/08.
Latitude 18.25 S, elevation 450m, 17.6 clear days vs 2.1 cloudy in August.

CoombellKid · #7 10-06-2007, 11:31 AM

Would you be able to nab the rest of the messier objects from the Cairns area?

I would have to go back over my logs, but I'm sure I've nab 100 messier objects
from Coombell. Although the objects in my list at the very northern end were
quite difficult.

regards,CS

glenc (Glen) · #8 10-06-2007, 11:36 AM

M81 & M82 are the most northerly M objects at dec +69.
M81 transits nearly 9 degrees above the horizon in Darwin.
Darwin is usually clear from May to Sept. (Climate change excepted!)
You can see M81, M82 from Darwin at 8pm in May.

I would be in that,but would have to give Duckadang a miss to be able to afford it

Maybe we could pool transport araingments

glenc (Glen) · #10 10-06-2007, 12:00 PM

Pooling transport is a good idea Ron.

CoombellKid · #11 10-06-2007, 12:14 PM

I would be keen too : ) pooling transport would be a great idea

I'm giving Duckadang a miss this year. Too much on, plus I want
to save for a bigger scope. Thinking of building a 16" dob either
that or buying one, but I hear the LB 16" a top heavy so my
ep's might have a lil problem considering they weigh upwards
of 390gm each.

But I would be keen on the Cairns trip next year.

glenc (Glen) · #12 10-06-2007, 12:48 PM

M31 would be 30 degrees above the horizon at 2am on 30/8 from Mt Surprise.

astroron (Ron) · #13 10-06-2007, 02:18 PM

M31 gets up to a reasonable hight from my location, but I was amazed how much higher it seemed from Mackay.
I think that would be a Astrocamp to look forward to.

CoombellKid · #14 10-06-2007, 06:08 PM

Glen,

Have you been to Mt Surprise before?

Can you give me the coordinates so's I can plug them into SNP.

We got cloud coming in from the SW at present Grrrrr!!!!....

regards,CS

glenc (Glen) · #15 10-06-2007, 08:36 PM

Been there once.
Latitude: 18.15 °S Longitude: 144.32 °E

duncan · #16 10-06-2007, 11:07 PM

Hi all,
I'd certainly be in a camp to Mt Surprise. I usede to go up there a lot years ago to dig for gemstones in Particular, Topaz,Amethyst and Aquamarine (Beryl). September is ideal, not to hot and still nice and cool at night.
Cheers.

glenc (Glen) · #17 12-06-2007, 04:38 AM

Looked at 3 galaxies last night with the 12" Dob @ 115x, N3621 was nice and bright, N2997 was faint and N3109 was long and very faint.
The bright star in N2997 was not a SN.

glenc (Glen) · #18 12-06-2007, 04:53 AM

An alternative to Mt Surprise is Undara Lava Tubes.
http://www.undara.com.au/

I wrote to them and this was part of the reply.
"Thank you for your interest in Undara Experience.
We do offer a 15% discount for all group reservations. (To apply for a group reservation you will need to have over 10 people in your group.)
We also have a large open area within our lodge. The ground however is extremely hard, however throughout past experiences it has been a prime area for star gazing and astronomy."

I notice on Google that they have an airstrip which might be suitable for astronomy.(lat -18.191, long 144.611, alt 750m)
http://maps.google.com/maps?f=q&hl=e...=13&iwloc=addr

Too much cloud interference for observing here last night, the jet stream
wasn't much help either.

astroron (Ron) · #20 12-06-2007, 01:18 PM

Contrary to my earler post I was able to see M101 last night , my report in my log as follows.
20:00 temp 9.5 C seeing 8-10 trans 8-10.this (was not the conditions at this galaxy as it is very low down) but the seeing was still very good for a so far north object, only 8.5 degs above the horizon
Large grey oval with exstensions, brighter in the centre, 14th mag forground stars seen in front of the galaxy.
Spent quite some time trying to tease as much detail as I could.
This observation makes this my 100th Messier object
