Stardust

I found a file from September 20th last year I hadn't processed. It's the region around the star Sadr in Cygnus with the Crescent nebula. Taken in Hydrogen Alpha 41 x 5 min exposures (3hrs 25.mins) Samyang 135mm @f2.4 Atik One-6 camera, Baader 7nm HA filter. Pretty much as wide a field as I can get. #atikcameras #samyang135

they are stunning images, would love to get 147

Great target for the 135mm.  It is a wonderful area and a nicely excecuted image.

It's amazing just how large some of these objects are.  I think the camera has done well for only 2 hrs, wonder how much better it would be with another hour or two.

That's come out a treat, 

Nice to see that area in all its glory,

Looking forward to your next wide field.

well done

Paul

Thanks  that lens is a little gem.  The cone has a lot of nebulosity round it

Im considering a OSC camera in the near future ,  I cant recall the last time I finished a project with my mono CCD, I think it will be up for sale soon,  Im have the 533MC or the 2600MC in mind, It makes complete sense with the weather we get in the UK , seasons change between the clear skies I get .

A nice image for only a few hours integration.

That was my thinking exactly mark, the weather is the main reason. These newer osc  cameras and dual band filters have really come on and opened things up. I still have my mono ccd, it's still better, but one clear night in a month doesn't complete an image.

I think it must be the '533' effect?  I've had less than 2 hours sky time with mine since it arrived 3 weeks ago.    

The weather has started off a but crap this year. Thus week is no better for me.

Very nice indeed! That's what I hope mine will look like with some more data. When I get some 🙄.

 

Thankyou, that was my first good night with the camera  Yes agree that more time is needed but you're off to a running start. Been a very bad start to the year, got to grab a clear night when you can.

The Flaming star nebula in Auriga 1500 light years from us. Nearly didn't process this as I didn't think there was enough data, glad I looked again.

Taken 9-01-21 with my ZWO 533mc Samyang 135mm @f2.8 Optolong L-enhance filter 24x 5 mins = 2 hrs exposure time. No calibration frames

just stunning

Very nice. The square sensor on the 533 looks like a really good match with the Samyang.

Thanks quite enjoying the set up. For a first light with not a lot of data and no calibration frames I'm pleased.

I've just got 97 x 180 seconds on M45  tonight so  hoping that will come to something

First light this week for the Samyang on a new ZWO533, misty night but had to get out there.

Nice effort.The wedge does work rather well. 👍🏻

Non stop rain here today so no observing for me.

 

 

BTW you might want to check the date in the title of the thread. 🤫

OOps calendar was still in November!!

I borrowed a solar wedge to try out today, quite surprised at the detail that's through in a 80mm scope. Only had a green filter to hand.

I found f5.6 right when I had that lens

I have all those filters in a manual wheel , pretty handy for getting the best one for the night

some lovely details

Another go with the Samyang 135 on my Fuji Xt2 with an Altair triband filter

22 x 4 mins @ f2.4 iso 2000

For various reasons I've  not been able to compare the 2 scopes. I hope to get set up for Mars and I suspect aperture will win there 

very nice, i've just done the same with a samyang 135, good to see a comparison

Excellent, the Samyang 135m is a beaut and very nicely framed.

Someone very kindly lent me a WO Redcat so I aim to do a wide field of it like yours with my QHY268C as a test

framing was pure luck as the ccd body was bolted down, just received a lens collar so hopefully will get rotation. Hope you get good results with the redcat, what a nice loan.

Nice one David, was thinking about buying this lens then went and bought a Sharpstar 150HNT f/2.8, regretting it now as I've wasted months trying to get a decent image out of it.

Dave

cheers Dave, I'd been on the fence for ages about this lens, how much use would it get for the price but i'm really pleased with it and will probably use it more than I first thought. Stepdown rings have been suggested to get rid of the star spikes, I don't find them too obtrusive but it's an option. Not sure what size ring to knock it down half or 1 stop.

I finally worked out how to get this attached to my Atik One-6. The main issue is back focus. I bought a ZWO canon/M42 adaptor and had to take some of the thread off in the lathe. This still didn't quite reach focus and a friend told me about the infinity stop adjustment. I can now get to focus, yey, although I will buy one the the bayonet replacement to m48 when FLO have them in stock as I think this will make a more rigid connection.

Processing is what I could remember and this is the result of 14x10 mins HA @F2.8 

I'm happy with this and that the lens is good 

Thank you. I'm pleased with the star shapes and that it gives a decent image at f2, not many lenses are good wide open. Might try f2.8 and will do calibration frames next but pleased what an unmodded camera has picked up. I was on the fence for ages but glad i bought one

Great start, will be even better with more data and calibration frames.

Agree,  it was more of a test of flatness of field.
