M42 from my future observatory site


Bill Long
 

Not all of them are bad. It is a game of camera roulette which I don't seem to win very often. 😉

The Gerd CTU is the right way to go, the built in "tilt plate" from ZWO is not very good at all. Your camera may be fine, and only need a tiny tweak to get it working perfectly. Others have had that experience, although I suspect its more of a F ratio thing. Faster = more problems when tilt is present. The smaller pixels on those cameras also bring their share of issues when tilt is present as well. 

My plan is to stay on the sidelines for this IMX455 and allow other manufacturers to release theirs. Atik and SX are both working on one, and both of them take great care in ensuring their sensors are squared. For those wanting to buy now, I would suggest the QHY600. Its on sale too. :)

Hi Bill, thanks for letting me know.. I wish I would have found this on-line before I purchased because  once I have my mind set… as soon as I saw the ad I pulled the trigger.  I did search a bit and noticed people talking about the need for a big (68mm) tilt ring  in front of AOG (which I have with the used package I found).   Almost entirely the discussions I found were about vignetting, and not really high tilt.  I do know there is the potential for light leakage around the 68mm tilt ring so need to fix that, but should not be a big issue.  The guy I purchased from did suggest the Gerd  Neumann CTU if I wanted a better tilt system for small amounts of tilt because the tilt ring is hard to adjust for small amounts of tilt.  I’ll keep my fingers crossed.   If I find it hard, I’ll get a Gerd Neumann CTU.    With all I have invested, donuts are unacceptable.  

I’d consider that much tilt, as your saying, a reason to return the camera.. wow.    Did you talk to Sam (I think that’s him at ZWO)?    Maybe he would have taken it back. 

I just purchased 2” Chroma filter set (3nm nb), but still waiting for the OIII which was just shipped.    I ordered my adapters from precise parts and will not get them till mid january.       

I wonder if there is any way for me to test this now?     Today I’m trying to wish the clouds away to get a view of the conjunction.    We have the Vermont pea soup over us even thought astrospheric says it should have been clear since 10am until around 5pm.       I’ve had one clear night in about 35 days.

I hope your skies are better!

On my ASI6200 it was so severe that I had one triad of the Gerd Neumann CTU maxed out and still didn't have enough to fix that portion of the chip. In my book that is way too much tilt and looks more like sloppy QC (more likely complete lack of QC) on the manufacturers behalf.

I'm eyeballing that Apx60 from Atik. They have a process they follow to get their chips flat when they build their cameras. I suspect QHY does something similar as those have less users experiencing terrible tilt. 

All 5 cameras I've owned from ZWO have had massive tilt problems. Buyer beware.

They canned CosMos due to Covid19 then when they announced their imx455 camera the name changed to Apx60.

Apx60? We can order Atik CosMos Mono or color from dealers with this IMX455 sensor, but which are not on the Atik site? Apx60 therefore replaces the CosMos?

Their OAG (QHY OAG-M) bolts directly to their CFW3 series wheel. Small prism on it (8mm x 8mm) but good enough for a Lodestar x2 chip.

That does not sound good.
The main problem i see with the QHY cameras is the lack of a good filter wheel with off-axis guider capability. (unless I'm missing something)

Hi Bill,
I think you are talking about the QHY294M-Pro. Some of us have received one, started testing it and wiping away the flaws of youth. Personally I use Sharpcap-pro and with the latest drivers. There are 2 modes, an 11M and a 47M an AD Sample Depth of 14bits in 11M and 12Bits in 47M. A test on NGC7635-M52 with my 130GT shows an advantage in oversampling the 47M mode.
The sky is not too much with us at the moment to make many and QHY still has some progress to make on the drivers in the 47M mode in the opinion of some.

Hello Robert,

Wonderful shot.  Just curious about the subs you threw out because of high humidity.  In what way were they so much worse than the others?

I have been eyeing the ASI12600, so I need to remain on the CFO's good side for a while yetEmoji

Hello Robert,

Wonderful shot.  Just curious about the subs you threw out because of high humidity.  In what way were they so much worse than the others?

I have been eyeing the ASI12600, so I need to remain on the CFO's good side for a while yetEmoji

Significant tilt. The QHY600 may be better. Less users reporting issues with those.

What kind of problems? I'm looking to buy one, but not if there are significant issues.

Looks great!

I had nothing but problems with my 6200 mono, but the smaller chip seems to be doing well. 

The new 4/3 mono with two different effective pixel sizes is really interesting. I picked up the QHY 284M Pro to check it out.
