The Dark flats should look just like dark frames, not green you need to cover the scope to take them, and should be the same length as the light flats….👍🏼

OK, probably need to explain better what I have done, the green image was a flat frame, I had to include one to take the dark flats. The image were the dust bunnies are flipped is probably because I had to put the image into gimp to stretch it. The darks are dark, and all times are the same in flats and dark flats. Hope this makes sense. 

Hello all,i am having issues calibrating my flats in APP,for some reason i am still seeing dust bunnies when i finish processing.

I have attached some screen shots,the green coloured one is with a filter and not touched,the others are stretched .

Any help would be greatly appreciated.

Just over 2.5 hours, just to see what was there.

102ed 533mc pro, only light frames so lots of back ground stuff going on.

Just over 2 hours on this,hope to add more tonight if skies stay clear.

102ed, zwo 533mc with 0.8x reducer,

Might get some help here. 

Around 2.5 hours on this,should have been double that but dont know what went wrong....most pleasing thing is i have finally got rid of the dust bunnies,i may have been using wrong length of flats.

102 ed...0.8x reducer and 533mc.

Don't be afraid to use the 2-sigma stretch -- it uglifies things, but points up problems nicely. In fact I use it all the time to identify gradients and such. I never save an image that way -- blecch! -- but it's a very useful tool. 

Is this in APP.?

Just load the file, double click it in the file list at the bottom and then check the "stretch" box on the right hand side if not already selected.

Will check that out, have the laptop imaging atm. 

I'm using APP, where would I stretch one of the flats. 

Just under an hour or 180 sec subs,with questionable flats ans dark flats,just cant seem to get flats to work right,but will hopefully work it out.

102 ed,533mc.

Its right. 21mm + 16.5mm + 11mm + 6.5mm = 55mm

Nice one, so all good?

looks ok if spacing correct?

That's were my confusion is, the spacing, not sure what way the train should be. 

Any one..... Possible clear skies tonight. 

Hello all, just a quick question about my setup, have I got this right, 0.8x reducer, filter drawer and 533mc. 

My RKE 28mm, apparently fairly rare first run Edmonds. Amazing floating views. 

Could only get 50 mins on this and  fairly bright moon but hoping to add lots more if weather permits, obviously just lights.

224?

 

Fat fingers... Lol

You won't go wrong with the ZWO 224 mc. 

Personally I don't think it's anything to worry about, it looks like tiny dew spots nothing serious. 

Hello and welcome. 

First is diamater of mirror and second is focal length. 

Hello all, I am thinking of upgrading from my 102ed to maybe a 5" frac, it will mostly for imaging with I bit of visual. It would be a used scope with maybe £1000 tops.It will be used with a zwo 533mc Pro. 

Any advice would be greatly appreciated. Paul. 

Thanks, will give it a try. 

Hi all i was just processing images i took last night and while doing so this message popped up.......any ideas.

First clear night for a very long time,3 hours of 300 sec subs,all lights, full moon.
