August 2021 - Anyone playing tonight

  • Jkulin changed the title to August 2021 - Anyone playing tonight

Well there will be nothing doing for me for a while as I have bought yet another scope. As we know the more money you spend the more cloud cover that develops. Maybe I should have just spent a quid on a cheap eBay scope.

Typical! I have bought another scope and it is forecast heavy rain for the next week. Sorry everybody.

Just found this above on the July thread, think it was terry posted it up.

 

So it's all your fault we are having all this awful weather.

I've just been given a very clear night as a surprise, given a hopeless forecast from CO. Have started capturing Lum to add to last week's Iris RGB. Hopefully will get 4 hours in mostly astro darkness, but will need to keep an eye on it in case the forecast clouds arrive.

Tonight is completely different to last night. Last night the dew point was less than half a degree from the actual temperature, so was very humid, and guiding was terrible. Tonight the dew point is 8 degree below the actual temperature, guiding is great, seeing is still not perfect, but 100% better than last night. The jet stream is going to be 36 m/s tonight, so that could account for the less than perfect seeing.

 

Last night my guiding was getting up to 1.2 RMS on occasion. Tonight a completely different story. No wonder this hobby can frustrate at times. 😃

You have good guiding tonight Brian. I wish we in my area of the UK had decent nights as it has been good during the day but as soon as the sun started to set it clouded over 😞

Hi Terry. Just looking at your SvBony article and there doesn't seem to be any way to post a reply. Found the problem. There is no reply box enabled in the whole Hardware, Adapters, Bolts section of the site. Have to let admin know.

That happens to me over here too, and it used to happen to me when I lived in the UK. It's so frustrating after having a clear day, then the clouds come in.

Thanks Brian I’ll let Paul know.

I'm setup with the RedCat51 for first light. I decided against the dual rig tonight as I only have a narrow window of opportunity tonight before the clouds come. I just want to see what the field of view is like in comparison to my Stellarium simulation. Also looking for edge to edge pinpoint stars just in case I need to adjust the camera tilt mechanism.

So just playing around with it for now not going for APODs 🌜

 

IC1318 is the target as there is fair bit of nebulosity in the area although I might take a snap of Andromeda too. Using the OSC camera tonight too as I haven't ordered the DSD focuser yet so would have to be running outside adjusting focus with the mono camera every filter change.

I reckon with that scope Terry, you would have no problem getting the whole N American nebula in the frame.

Yes I hope so. The simulation seem to be good and have been fairly accurate in the past within Stellarium.  Green has turned to amber for me though in the weather apps such is the fickle nature of the UK skies but still hoping I get a little imaging time later on.

First sub is in and it has sharp stars corner to corner. Focusing the RedCat51 manually is very sensitive and needs a very light touch. I ordered the DSD focuser for the RedCat earlier today so should have it in place Thursday or Friday and go to auto focusing again. It’s surprising how reliant you become on automation.

 

As I type the clouds have covered my target so I might wait for 30 mins or so before calling it a night. I got what I wanted.

I didn't get much data last night and as it happens I was only able to integrate 36 minutes of RGB from my OSC using the RedCat51 due to cloud. I purely wanted to see what the FOV was like and see if there were any issues with coma on corner stars as had been reported on other forums.

But happily none was seen and the RedCat is good to go. The DSD focuser should be with me tomorrow.

 

In the meantime here is 36 mins (6 x 6minutes) processed showing good field of view and sharp from corner to corner. The target is IC1318 not that that matters. I didn't reduce any of the stars. The image is spoilt by the big one with lots of halo around it but I'm not too bothered. Not after any merits for this one.

 

Guiding was very poor too due to wispy clouds.

Looking good for only 36 minutes. 20 or 30 hours will look fabulous as long as you miss Sadr. 😁
