It could still be droop. Either in the focus tube, DSLRs are heavy, or the camera itself if you are using a nosepiece. Also it is not unheard of for the sensor to be tilted in the camera.

Have you tried rotating the camera and seeing if the corner most affected moves?

As long as they don't have to self isolate as soon as they land! 🤪🤧😷

Fitting a crab apple in somewhere might be a plan...  and there's crab apple jelly, too

I wondered where all those little crabs on the beach came from! So they grow on trees! Making jelly from them sounds a bit icky though! 🤪 

Both very nice images. Well worth the wait I would say Lee! 

Lovely sharp images Craig! I'm going to have to upgrade my Windows XP computer so that I can download updated software. 

I believe you need to change the properties of the folder that your subs are in. Right click on the folder and then select 'Properties'. Then uncheck the box that says 'Read Only'. 

I think that is right? HTH

That's a very nice image! Pin sharp detail on the full image. I'd say you don't need to do anything more than you are doing now!

Nice surface detail in your images Paul. Especially the ejecta from Copernicus, wrinkle ridges and crater chains.

Glad you're enjoying your astronomy again Chaz!

It takes me over an hour to set my equipment up so I know what you used to go through. Unless I really make the decision early that I'm going to go out (not easy with the poor forecasts) I can't be bothered half the time. 

Not a book, but this lecture is very informative:  

Hope this helps.

Wow; what 'scope are you using? I don't think I've seen M81 filling a frame like that before. Real shame about your RGB data. I hate it when you think you've got good data only to find out that's not the case. 

You're welcome. I know it is very hard to step away from something. You always think 'if I just do this or tweak that...' and that's when the wall falls down!  I believe that is a big problem for artists (painters etc.), knowing when to stop.

I think I prefer the one you posted on Tuesday with the tweaked palette and dynamic range to be honest. It looks more natural. The artifacts around the red giant towards the right hand side are also more apparent in the latest image. 

I know what you mean. It seems like you should post the same day, or certainly within 24 hours of obtaining your subs sometimes. Normal day to day life comes first though, as it should. As long as I can get something that I'm not too unhappy with, I'm not too fussed about how long it takes.

Very nice image Rodd!

Certainly sounds like you had a bit of a battle of attrition to get your subs! I think the end result justifies your sticking with it. As for 27 hours of subs!!! I dream of 27 hours view of a single object.

I think most things in this hobby are 'no pain, no gain'! It takes me, probably, over an hour to set up my equipment and then it quite often clouds over just as I go out after letting the 'scope cool down for an hour or so. Either that, or it remains clear, but my equipment doesn't want to communicate between its various parts. 

I had a look at your Flickr pages. You have some lovely shots of the various phases of the Moon. Good definition even when zoomed in.

Despite using a Bahtinov mask and 'Bahtinov Aid' in APT, I think my focus is a bit on the soft side. It was, however, the first time I had done any serious astrophotography for such a long time that I decided to post anyway. 

Lovely sharp images Steve!

A couple of mosaics of the Luna terminator from the 6th of Feb. I kept the roi quite small to obtain about 80fps and captured 5000 frames in each video. These were then sorted in pip, stacked in Autostakkert2, wavelets in RS6 and stitched in MS Ice.

So sad to hear this news! I remember Heather Couper from the TV in my youth. She was so passionate and engaging about science and astronomy. A sad day. My thoughts and condolences go to her family and friends. 

I've used a couple of layers of self-amalgamating tape on my particularly nasty Celestron CGEM mount knobs.

YouTube has lots of really informative videos on astro image processing in a number of programs including Photoshop. 

Signed.

Brighton & Hove Albion also have a massive training ground built 10 - 12 miles away on the edge of a village called Lancing. The development, which is about to have a large extension is built on a flood plain and right up to the back gardens of dozens of homes.

The training grounds floodlights illuminate the sky for miles around. Since the development, the gardens of the homes have started flooding; which they have never done before. The council in there wisdom are also in the process of agreeing to a development of 600 new dwellings and an IKEA store on another part of the flood plain!

Back in December of 2018 I bought a  Startech 7 port powered USB  hub, which I fitted to my new on 'scope DIY power hub. After a long break from imaging I am finally getting back into the swing of things after watching a few YouTube video tutorials on the various programs that I use.

Anyway, the other night I was simulating an imaging session to test out the various options only to discover that four of the seven usb ports weren't working. I looked up Startech's website and found that they have an online returns form. I duely filled in the form, including a copy of the receipt from an online retailer and sent it off.

The next day I received an email to say that my request for a replacement under warranty was approved and shortly after another email to say the replacement had been shipped! To be honest I thought they would say that it had been too long since the purchase, so I was very pleasantly surprised to receive a positive response and so quickly too.

What excellent customer service.  Well done Startech!

Very nice. Lovely subtle colours. I don't think I've seen this target showing so much depth before.

I used these on my power distribution box.
