My new scope! I'm going to the dark side!

[stephenmcnelley]

Good on ya Mike, push the boundaries a little, chances are you will come up trumps with hard work if past imaging results are to be gone by, sounds like an interesting challenge with that combo. A 12" in the back yard,

a dying breed, the old dob owner.............unless of course they owned a eq before like houghy!

Complete bollocks, Davo the dob for visual work will rise again in everyones life at some time
That sort of convenience can be banked on

Welcome to the dark side Mike, I've always thought that dobbers were wannabee go-toers.

[anj026]

Hey Mike

If the 12" GSO is ok on the EQ6 maybe I could get away with a 6" f15.
Just kidding, I don't think I want another equatorial just yet after selling the EQ5. I wish you all the best with the new set up, your planetary images are outstanding.

Cheers

[bird (Anthony Wesley)]

C'mon Mike, bring the 12" + EQ6 to Lostock. You know you want to...

umm, maybe best to check that the camera comes to focus beforehand...

Drawing a very long bow there acropolite..

When i retire from astronomy, poor and broke.... a humble 12-13" dob will be the old faithfull choice at hand, amongst other possibilities, by then i will know what i want to observe.. and have an even shorter attention span..lol.

[Astroman (Andrew Wall)]

YIKES!!!! a 12" on an EQ6 wow thats pushing the boundries, although it can be done easily. One thing that could give you a bit better support would be to get a losmandy dovetail head on ethe EQ6, with the wider dovetail it might give a bit more stability. But you never know it might be right on the money..... I wouldnt be so worries about the weight its the canterlever (I think thats the word) action of the tube that would cause trouble, than the weight. The EQ6 itself can still push around 50lb of weight, visually with a short tube..

Hopefully by then GSo will have a 20" Dob out

[stephenmcnelley]

Stuff that Astro, LOL.... a 20" dob?!! no way when i am 80 years old and a bit feeble... thanks for the thought though..laughing. i am gonna have to work until i am 95 years old to pay off the current debts so the future ambitions aren't to grand, long as i can see and share night time stuff.

Where would I get one of those, Andrew?

[Astroman (Andrew Wall)]

HaThere used to be a guy on the EQ6 yahoo group that made em, if you got the drawings any engineering firm could turn one up.

Oops better get back onto thread topic

[netwolf]

Mike you beat me to it congrats. I am almost there a soon to be equatorial convert. But I think I will eventualy switch the 10" newt for a C9.25 SCT. And keep the 10" as a dob.
Regards

[h0ughy (David)]

LOL Mike you know the score, congrats! now go on get another just for fun!!!

[[1ponders] (Paul)]

Don't worry about the polar alignment Mike. Al got a good lesson last Lostock with K3 and h0ughy got an extended lesson at Astrofest using a reticle, so either way you'll be set.

[[1ponders] (Paul)]

Oh ......... Congrates Welcome to the deep dark. You will get hooked

[sejanus (Gavin)]

hey mike this might be of interest. this is an eq5 i think, using a strut to help support/stiffen up long tubes.

Don't remind me, I have had nightmares ever since

nah I'd never go there

yeh you're both right - i'm planning on putting the 12" on the EQ6, but I won't sell my 10" until I'm sure the 12" is not too heavy for the imaging I want to do. At 10m focal length, even a slight breeze can cause frustration with the planet jumping around the 640x480 field of view - so I need to make sure the 12" is suitable.
If it's not, I'll sell the 12" as a dob and keep my 10" newt and put it on the EQ6.

Does he use it for visual or imaging?
What is the purpose of the chopped off legs? For reaching the EP easier, or better stability with a lower centre of gravity?

It's ok for visual, time will tell how it is for planetary imaging.

Maybe.. it will take up more room in the car and I've got stacks of stuff to bring to Lostock already so there mightn't be room for it.

Why wouldn't it?
It's a 12" f/5, same as my 10" f/5 but a longer FL. My DMK doesn't come to focus at prime focus in the 10", but with a 2x or higher barlow, it's fine.

Enrique had a 400mm aluminium dovetail plate made up - you can see it in the pictures. So the standard one has already been replaced. The new longer, stronger dovetail plate apparently increased stability noteably.

Thanks Paul, good advice.. i'll hit those 2 up

From Mick Pinners thread, i'm quoting Geoff:

The platform is stable, but that's not why I want to go to an EQ mount. I can align the platform no problems and generally get good tracking, however at very long focal lengths it highlights any imperfections along the tracking line and it can go from having the planet in the FOV to scooting off the FOV without touching anything.
It's also only got a speed control in RA, so I'm constantly adjusting it to keep the planet centered. I want to be able to sit back and have the accurate consistent tracking on an EQ mount, with a hand controller to make the adjustments in both RA and DEC!
It will be especially helpful when imaging the moon, and trying to find the feature of interest by just using the hand paddle to pan around the moon.
Try doing that with a dob at 10m focal length while looking at a laptop screen!

Thanks all for your encouragement and feedback. I'm really excited about the prospect of more relaxing imaging. The goto will be very handy for Neptune and Uranus later this year too And with accurate tracking i'll be able to do longer exposures to get more brightness and detail out of those faint buggers.

I am looking forward to getting an ED80 in the future to do DSO work with my 350D, but planetary/lunar imaging will always be my #1 love.

I'll also be getting the dob base for the 12", so I can still use it as a dob for quick visual use if I need to.

Thanks, i'll post more pictures after Saturday!

afaik he is just visual but i saw it in action and it works fine. he chopped the legs to reach the EP, alas doing so makes the foot print smaller and therefore less stable. there are ways to combat this to i believe

[wavelandscott (Scott)]

Congrats Mike...that doesot sound like th dark side at all!

Hope you enjoy it!

CS, Scott
