QHY8 First Light.

[AlexN]

Happy to report that I had the QHY8 out for a few hours this evening, and I'm rather impressed with the results.

Heres the images for tonight

M8 30x45sec + 10x60sec.
M20 20x45sec + 5x60sec.
47Tuc 20x30sec + 20x45sec


I have plenty more data to sort through from tonight, M16, M74, NGC2070 to name a few targets..

Only one problem so far is that there seems to be either dust on the QHY8 sensor, or maybe moisture buildup on the chip.. its hard to say.. but there are a fair few marks in the image in uniform locations in each image.. I dont think they are from the scope, as they didnt show up in any of the shots with my DSLR yesterday.. I have inspected the camera since use and there is some moisture in there around the sensor, but i can see any on the sensor itself..

Oh, and the 4th pic is what my neighbors make me live with... :D

Thanks for looking.
Alex.

OH I HATE FLOODLIGHTS TOO!
Nice results Alex! you might have to bake your silicone stuff to stop that ice/moisture forming on the chip?
cheers

Hi Alex

Great series of 1st light images – you’ve been on a very steep learning curve with all that new gear and you seem to have mastered it quite well. Top job.

The M8 and M20 images look too red on my monitor, I think they can be much improved if you can remove the overall red cast and showcase them against a more neutral sky. The blue in the Trifid may pop out more then.

What a bummer about that rotten neighbour!

Cheers

Dennis

Looks promising Alex. Gee those flood lights make for a really tempting target. Did your QHY8 came with a slug gun? :whistle:

Hi Alex,

Great first images man!
I'm glad you finally got some photons on the QHY8 at last.

I'd save the terrestrial shot for the Photo of the Month challenge,
when the subject is: Contemplating Homicide

regards,
Steve B.

Not bad for a beginner and first light with the QHY8 :)

Pzzzzzzzzzzzzzzt, the word bazooka springs to mind for your neighbour.

[dugnsuz]

Very nice first attempts with the CCD Alex - heaps of potential when your neighbours go to bed and turn off the lights.

Considering your images range from total exposure times of 5-15 minutes I think you might be right to be happy with the results/purchase.
All the best
Doug

Good to see you got it all working Alex. I had a fiddle again, can't help myself. It is hard to work these little files but this should give you some idea of what you are capturing. One sugestion is to watch your histiogram with all 3 colours open and adjust each colour independantly. You have plenty of data to work with and a lot of colour but with nearly a full moon and those flood lights you don't stand much of a chance.
Hope you don't mind.

[GrampianStars]

very nice I'm sold great shots :thumbsup:
and
btw a Marlin .22 gauge rifle with Bushnell scope will sort out your lighting issue from a long way out ;)

[Tilt]

:lol:

[Craig_L]

Which scope did you use Alex?

[AlexN]

Thanks to everyone for the comments. I'm really quite happy... appart from the fact that its now been 12 hours since I brought the QHY8 inside and its still got water visible around the CCD... :( I dont thing its supposed to do that..

About the flood lights... I was thinking less about a .22, and more about a .50 or better yet.. some duct tape and a blow torch... nothin like a bit of torture....

Doug, I appreciate the edit. It really clearly shows that Dennis was right, and the background was too red. I'll have to work on that...

Craig_L : They were taken with a William Optics Megrez 102,

good start..as for dust, I too had plenty on the sensor when I got my QHY8

Theo recommends using methylated spirits to clean but I have held off so far, relying on flats to get rid of them, but may Doug or Rob (astrod00d) has tried cleaning

[Tandum]

Glad to see it's all going Alex. You might try asking the neigbours to tilt the lights down for you.

[matt]

Congrats on first light, Alex:thumbsup:

Shame about your neighbours. Are you on talking terms with them?

Might be worth saying g'day and seeing if you can work something out.

I was in a similar situation when I lived in Canberra. My neighbours didn't know their backlight was causing grief until I spoke with them and they were very reasonable.:)

[Astrod00d]

Yep, there was a lot of dust, and a blob in the lower left corner that looked like solder flux, on the sensor when my qhy8 arrived.
I cleaned the dust out with a blower bulb while holding the QHY8 sensor-side down (so the dust falls out not in!). The flux blob came off with methylated spirits on the corner of a tissue. I just dabbed the corner of the tissue on that very small portion of the sensor where the blob was.

I still have dark spots all over the sensor that look like residue left over from factory cleaning, however they're barely visible. One day, when I feel braver I'll clean the entire sensor with methylated spirits.

Last but not least... Great images, especially for a first run with a full moon and floodlights. Need a bit of work on the colour balance, that will come easily if the raw data is good, and it looks good!

Cheers,

Rob

Hi Alex

These shots are much better than previous posting of 350D shots ... well done especially considering those prison camp spot lights ... as suggested if you are on speaking terms with the people I would knock on their door and explain that they are a problem ( the lights not the people :lol: ) in the nicest possible way. " You catch more flies with honey than vinegar " is a good old saying.

If that doesn't work MOVE like I am going to :rofl:

My ST2000XCM had lots of spots on the sensor when I bought it and I removed them with what the SBIG manual recommended ... Isopropyl Alcohol ... available at Dick Smith's for around $7.00 and applied with good quality cotton buds i.e. not sticks with minimal wrapping. Just be careful ... worked well for me !

I'm sure you are going to have a lot of fun with your new gear ;).

:thumbsup:

[drmorbius]

That's great Alex... your neighbour's not coming to Barambah is he?

[AlexN]

Thanks guys...

I've had a play with the levels and color balance on the M8 and M20 shots.. I think the 47tuc image is pretty right as is..

I am on speaking terms with the neighbors, and whilst last night was annoying, its very coincidental that it happened on the night that I was going to image... They are usually well behaved as far as the lights go.. mind you coming into summer they may get carried away with outdoor entertaining in which case I'll have to work something out...

Randall, If anyone at barambah has a white light even remotely that bright, i will personally shoot them. Im not about to drive 200kms to suffer light pollution woes! :D

I've looked at the camera again, and the moisture inside it has dissipated, I will have a go with a rocket blower camera cleaner and see how that goes, failing that, metho or isopropyl and a high quality q-tip might be in order...

Anyways - redone images.

Nice going with the QHY8 Alex. Pity about the neighbours lights - persevere and now is a good time for you to be visible to them and then ask them over to view Jupiter. I know as it works with my neighbours and they now ask if Im going to be out so they dont accidentally switch on a light. Doesnt help Brisbane CBD is only 4.5Km away but work with what you have
Allan.

[Striker]

Keep them coming Alex.

Nice start with the new gear...be careful not to clip the histogram with tuc 47 with too much contrast.

[Matty P]

A great start Alex, you are well on your way now. :)

Looking forward to more. :thumbsup:

[Hagar]

Don't be frightened about cleaning the sensor with Metho or Isopropyl Alchohol. The glass cover on the CCD is very hard and almost everyone I have spoken to on QHY forum recommends cleaning with a Q Tip or CCD cleaning swab and alcohol. I have done it on several occassions and it even helps prevent Ice forming on the CCD.
I use Isoprpyl alcohol bought from a chemist. (Expensive at $35/ 500ml bottle) but it leaves no residue. I also bought ccd cleaning swabs from a local camera store. It pays to do the clean using a magnifying glass as the smallest speck shows up as a big blob on the image.

Give it a go.

[seeker372011]

thats handy to know.

[AlexN]

Got some Isopropyl today.. will give it a clean tomorrow and run off a flat frame to see how I went..

[EzyStyles]

nice first light alex. the reprocessed versions are nice. ouch on the neighbours floodlight :(

[Jen]

:eyepop::eyepop: OMG Alex that light would drive me crazy arhhhhhh :bashcomp::bashcomp::poke: i would go straight over there and pull the fuse out and clip a few wires so they have no power all weekend hahahah :lol:

[Jen]

:DOh Alex i forgot to mention that the pics look great well done :thumbsup::thumbsup:

[AlexN]

Thanks Jen & Eric, Shame I have to go to bed early tonight, its very clear and dry tonight, Every night that I can get out, the whole yard is WET by 11pm, the one night where I have to be up early, dry as a bone... Go figure! :D

[Screwdriverone]

Jeez Alex, dont you ever take your time?

That 47 Tuc is is superb!

Crisp and clear and really well defined.

Well done, the others are great too, but DAMN, that 47tuc knocked off my socks, and I wasnt even wearing any!

Top stuff.

Chris

[AlexN]

Thanks mate...

I must admit, I was ever so happy with the 47tuc image myself.. Looked at it, and high fived myself :)

As far as taking my time... hah.. No! :) lol..

Live life in the fast lane!! :D

[Screwdriverone]

Ha Ha, hi fived yourself, classic.

Its a bit embarrasing when you attempt to do that and miss though :sadeyes:
Keep it up, I look forward to the next $6400 photo (see what I did there? :lol:)

Cheers ;)

Chris

Oh and by the way with the neighbours' lights, one idea is to sneak over when they aren't home, steal some rocks or gravel from their garden if they have any and subtly chuck em at their patio lights, when they find all the smashed glass and the rocks as the evidence, they will think that one of their kids did it, or someone else in their yard. You can then just carry on and say "mate, no idea how that happened??? :innocent: :whistle: :lol:

[Tamtarn]

You have done well with your first try with the QHY8 Alex The reprocessed versions are certainly showing that the data is there. Still seem a little saturated on our monitors but looking better.

Under good conditions your new set up of the C11 & QHY8 should produce some amazing images. Something to look forward to.

[AlexN]

C11 first light should be tonight... dont know if it will be planetary/lunar imaging? or just, some visual observing... but im itching like nothing else to get that big bad boy under the stars! :D Its just so... imposing!! :) I love it, I love it to bits...

[Jen]

:lol::lol::lol: Dont you drive too fast from work to home Alex hahahha i can see you doing 100 miles an hour just to get home hope ya have a good nite cheers :thumbsup:
