Hi

Don't forget the full moon too;) 

We sometimes image from a city centre location and find that the CLS filter works great and allows us longer exposures than unfiltered but remember that it is light pollution dependent and we've just discovered that there's not much you can do against the moon.

With a 10" I'd say maybe 2 minutes would be enough? The CLS may get you double that. Be prepared to experiment; you've a good while before m3 rises anyway, so practise on the open clusters. Go for as long as you can on the globular.

Do post your results.

Cheers and good luck.

Thanks 😊

I thought moon would be far away from m3 by the time it's high enough to image . Yes gotta do some experiments tomorrow.

I've heard lp filters give a blue image ? How to process those photographs ?

Hi everyone

I want to use the local clubs equipment tomorrow night and I'm planning to shoot some bright open clusters(m41.47) and a globular cluster(mostly m3).

I live in a bortle 6 area and the setup is 

Gso 10 f4, neq6, unmodded 700d, ASI Guide scope and 120mm camera for guiding . We can guide upto 5mins easily .

So I was wondering on how long do I expose the frames, iso etc

I have no hopes to point at a Galaxy cause I know I won't see anything because of light pollution (I may be wrong just a guess )

Are light pollution filters effective?

Thank you

Just curious, what guiding setup would be ideal to start with the 130pds on heq5 to good more length on the subs ?

Hi.

Which refractor would you'll recommend to mount on a eq 3 mount with RA tracker or sw staradventurer both having Max payload of 5kg.

Or should I go for a lense like 134 f2 or something. Need this for widefield nebula etc.

Thank you 😊

Hi , are images clicked using a ra tracker and eq3 mount eligible for this challenge ?

Hey everyone

I am looking forward to purchase a laptop with good battery life to use it for astrophotography as I have to move out of the city to do astrophotography. About 5-6 hrs of power is good enough .will be running software such as stellerium,PhD and APT on it . Any recommendations?

Thank you 😊

Hey everyone,

I was thinking of taking out the astronomy clubs equipment to do some astrophotography. A Gso 10 f4 , neq6 and my Canon 700d unmodded. A ASI Guide scope and guider

I am thinking of either the crab nebula or M78

I remember that the crab shows up in a 30sec test shot. M78 was not that impressive in a exposure with same settings . I can do 3mins guided exposure . I can strech it up to 5 but don't wanna risk it cause of wind .

Will be back home by 1am or something so was planning about 2hrs of data or maybe a little more .

M78 looks bigger in the FOV .crab is small but is unique .

Any advice on which of the targets will be good for a 2hrs imaging session ? Don't wanna waste time on doing too many test shots .

Thank you 😊

Hello 

A solar eclipse is upcoming and I dont wanna miss a chance to photograph it

I was wondering if I use a cardboard sheet, cut it according to size of camera and apply solar filter on it, will it be safe to use with the dslr by placing it above the lense? 

Thank you 

The lagoon sub is nice 

Moon though the clouds. 

And my attempt for the lunar halo with my phone 

Looks like Dave is in a good mood

IT looks like a bazooka 

I think I'm eligible. No processing done. Gso 8inch dob. Saturn is with a c14 and manual tracking (cge doesn't work) using a 3mtr focal length scope is hell for me as I'm a beginner  

There are some telrad charts available. Very helpful. 

As yours is goto. You need the view finder very little actually. ?

I once was awake all night shooting constellation and when I went home 120km away I realized they were jpeg!!!!! 

Nice image! A flat will make it professional

Nice image. Which lense /scope did you use?

Yes, but be aware that a long journey to an 'orion class site' might prove disappointing.

By orion class site. Do you mean a place where the orion arm can be seen? What do you feel will be the naked eyed limiting magnitude of the site? At my dark site. 20km away from a town I can see it very well. 

That's a nice image. I think there is a little of more blue in it. 

IT may be my screen.

@Stub Mandrel. 

Which type of eq 3 do you use?  Goto or with ra motor drive?

Confusing polar alignment and star alignment I think , drift alignment can be done with any GEM mount.

Dave

Yes just Googled it. Will give it a try

But isn't drift alignment done with a goto mount? 

I think this is a good place to post my question. 

To start with I have  a eq 3 mount with ra motor drive and no polar scope. I got 3mins exposure with a 50mm lense. 

I am thinking of using a Astele 95mm makustove for lunar, solar and hopefully some bright dso. 

I know that f ratio is too much. 

I may use a 150/1200 reflector. 

Question 

1- how can I improve the polar alignment without a polar scope 

2- with the 150/1200 scope how much second exposure can I expect. 

3- have I provided the necessary details? 

Thankyou

i hate them and also like them actually.

depends of what type of object im shooting. like clusters, i hate spikes.

now im confused on what to buy after reading this forum

130pds or evostar 80ed

You shot it at 300mm? Great image! Stars look good also. You should have taken more subs but of 2mins.my opinion I may not be the best
