Very nice image Dan. Try using Pixinsight's SCNR to convert the green into a nice blue. I've also been imaging NGC6992 and have collected over 10hrs of rgb data. I combined the data and was shocked at the amount of stars in the image. The nebulosity was difficult to see. I'll need to reduce the amount of stars to bring out the main subject

Hi Steve, i used SNR down to 70% to reduce the green but tbh the blue imo is quite a turquoise look so left it there, but yes maybe down to 60 wouldn't hurt. Starnet ++ is fantastic for stars and can use as a mask as well, so mask the stars and pop the colour in the nebula with messing with star colour. thanks again

That’s really good. Stars nice and colour just right in the nebula. 👍🏻

Many thanks, appreciate it . such a beautiful target

Or better still a used C9.25 ... As for getting a planet on a small chip, make sure finder is aligned as well as possible to camera, defocus the scope a bit and ramp up the gain, it's much easier finding a big bright donut than a tiny planet.

Thank you

If you have already a HEQ5, you should consider a Skymax 150 or even a 180 for planetary imaging, I think.

 

N.F.

 

Thank you I'll take a look. I was looking at some cheap 200p's yesterday as I already own a 2 and 3x Barlow

That's a great combo, you won't be disappointed!

Thank you! just need some clear skies!  all the best

Oh I see... well plenty of people do get great planetary images with a dob, though I'd suggest budgeting for an equatorial platform if you go down that route.

A 200pds would be fine, 8" aperture is enough to get some real detail, couple it with a decent 3x or 4x focal extender and you should be able to get some nice images. 

Whatever you do, I'd think about getting an ADC too, money well spent in my opinion! 

Great thanks Craig, appreciate it mate

If you already have a heq5 why would you want to get a dob? Just plonk an 8" tube on there and you'll be fine. A C8 would be good but also consider a mak or an 8" newt. 

the dob was more due to not having to keep taking my frac off the mount but the more I think of it a tube def seems the better option. Is the 200pds any good? I had the 130 and it was great so image the 200 should give a lot my FL for planetary but keep the imaging situation well 

Moved on from my 600d to the asi 294mc Pro and optolong L-enhance. Hurry up clear skies!!

I suggest you check the 'Planetary Imaging' section of the forum to see what gear others have been using.  It's not impossible to image with a Dob (and it's not impossible to cross the Atlantic in 🙂a rowboat. )  But the best tool for the job is a SCT of aperture 8" or greater.  The depth of focus makes it easy to attach imaging accessories - cameras, atmospheric dispersion corrector, flip mirror, filters.  As for the mount, either an alt-azimuth or a equatorial mount will serve, but it makes the task a lot easier if the mount is rigid, tracks, and has a minimum of backlash.  Without accurate tracking, a planet will go out of  a 320x240 pixel ROI very quickly.  The CPC800, for instance ticks all the boxes with its substantial fork mount, mimimum backlash, and GoTo but unless you get a great second-hand deal may cost more than you want to spend.   I also tried using a C8 on a EQ-5 Pro Synscan mount, but by comparison with the CPC800, the amount of backlash was quite annoying, and the potential for a 'meridian flip' when working near meridian transit equally annoying.

And you need a good finderscope - just getting a planet onto a small camera chip is a challenge in itself.

Thank you Geoff, some useful info appreciate it. I have a 50mm guide scope i could use for my finder and i was hoping to use my HEQ5 for the tracking, im wandering if a larger PDS would be the better way to go tbh ?

Morning, I have a dso set up but as per usual in this rabbit hole of a hobby im also looking to grab a fairly "cheap" planetary set up.

I already have a asi 224 so ideally would like to use that in conjunction with an 8" or 10" Dob. I had an XT8 dob a while back (that i now regret selling) but always struggled to image with it, could someone advise on the best extentions and materials needed to make my 224 work with an 8 or 10" dob for imaging mars this coming oct.

many thnaks

Nice one, I might try something like this myself

Thabks Adam, yea give it a go mate it really works well ! Good luck

From what I can remember the L-Enhance isn't great for galaxies.

Cheers mark. Just watched a vid on the L pro on andromeda and it looked like it worked very well!

Hi, I've had some spare time, a chop saw and some wood so I make a wind/ street lamp protector for my rig. It worked really well last week so pretty happy overall.

I've since lowered the middle bar as it interfered with a high target and also punched holes in it for an eyepiece stand 😎

It tucks away nicely down the side of the house and has wheels to move around.

At a guess I would say you won't need anything too strong. Maybe an L-Pro or IDAS D1 for Bortle 5 skies, though it will depend on if there are any strong light sources nearby.

I have a street lamp Mark but I made a make shift cover for that so I'm ok, I more want to pull some colour out but suppress the LP a little.

Am i right in saying the L pro isnt great for galaxys or is that the l enhance?

A lot will depend on what type of light pollution is nearby.

There's some handy info on this video.

 

Thanks Mark, will have a look at this video for sure. Just really torn on what to buy so hopw this helps my decision 

Hi, I've been looking at the L-enhance, L-pro and tri band filters and posted a wanted add for one on SGL...

I've been sat thinking and I ideally want to block some LP but also enhance some colour from my targets, I used to have a HA filter for my dslr before I switched to CMOS and just found on the sparse clear sky nights I just couldn't finish a HARGB.

Is an UV/IR cut filter the better option for me? 

I live in bortle 5 skies and try to get 2 -4 hours per target time permitting.

Does the L enhance shoot narrowband or does it just enhance the colour while blocking some LP? 

Many thanks for any input 

Dan

Hi , just before i pull the trigger on a new cam (switching from dslr) ive noticed that on astronomy told in the ccd suitablity it suggests there maybe slight under sampling at ok seeing due to it being "2.15 pixel where as it suggests being between 0.67 -2. is this really going to affect anything for mew at all? its a lot of money to spend and get the wrong cam   Im using an 80ed with a0.8x reducer/Flat.

The reason i didnt want the 183 is because it really impacts my fov?!

will the 294mc pro be ok for this scope?

thnaks

I have an older AA80 triplet and love it. The optics are as good as they look.

That's great to know and fills me with confidence many thanks

Now that looks a really nice piece of kit... good luck with it 👍

Thank you I'm very excited to get out there. Will possibly post a review at some point 

Been imaging with a newt for about a year, have now pulled the plug on my first ever frac. What beautiful engineering!! I'm so impressed, I hope it works as well as it looks and feels

It would but you can use a flattner with it and the 61 is F6 and the reduced GT71 is F4.7 so much faster due to the larger aperture. £1060 with the WO guide scope and the flattner. It would be less with a no reducing flattner. But you will do well either way I would think.

Adam

I think id grab the 71 if it had a 1x flatner, i really dont want to go to 336mm FL, is the 71 that much better then the 73? and due to the 71 being a triplet is there still a huge need for the flatner?
