Hi to everyone, I used to do some astrophotography in the past with a Celestron AVX and DSLR but after few month had to give up for several reasons, including light pollution (I'm living in zone 3 east London), and also working shifts. Now I want to start again, and this time more serious. I've been searching around for a couple of months to choose all the gear and I'm quite happy with the list so far although it's a bit over the price I planned at first.
I will get an William optics Z73 with his 50mm guide scope, a flattener/reducer 0.8, light pollution filter IDAS D2 and as camera I will use a Canon 600D modded and I will buy a ZWO 183MC Pro, after so much research, I'm very happy with the scale and framing I will get with this combo, but I'm starting to get confused with the mount.
My first idea was to go for an HEQ5 Pro, as my previous experience with the AVX has been awful, then I realized that the FLO, sells that mount with belt modification and also some cleaning and tuning if required, I heard that it's a big improvement over the stock one and the price it's ok, but another important factor for me it's portability. Unfortunately, my garden doesn't allow me to do much so I will need to carry around on trolley, for a km walk, I'm a strong person and been doing plenty of time with the AVX, so my confusion came recently when the iOptron mounts entered my radar. I start comparing the heq5 pro with belt, with the iOptron cem25EC and the CEM40 without encoders, and I'm so unsure of which to buy, the cem25 seem to be the equivalent of heq5 at least speaking of payload, but in some threads I read people saying it's a bit fragile so kind of remove it from the equation although the weight it's interesting for my situation, then the cem40, seem to be quite similar on weight to the heq5 but with higher payload and that's interesting too as I will buy a C11 at some point.
Now it will all come down to the accuracy of tracking I guess, how the heq5 and cem40 would compare on tracking and guiding? If the cem40 it's better, I would probably go with that since it holds more and would last longer as I don't plan to get anything bigger than a C11, but if the skywatcher it's better, I could decide to go for that, and when I move to a place with better garden then get a second mount with higher payload.
Apologise for the long post and my english.
I like live stacking as I can see the image develop and it saved my hard drive being cluttered up with thousands of images.
The downside, I have found is that if a cheeky wisp of cloud comes over, it often gets included (in spite of trying to clamp down the FWHM settings). Some of my images then have a like a grey smear over them.
Then after and hour of live stacking I find it looks just like a greasy smear over the picture- which is a real pain to try and post process out.
Always seems to happen when I pop indoors to make a drink etc.
I noticed that there was a setting on SharpCap. to save the stack- save and reset. Which I have not used yet.
So Im thinking maybe I should do shorter live stacks eg. 30s for 5-10 minutes and then stack the results in A!S or DSS, so I can weed out the poorest sets, and I least I get something.
Gives me a chance to do any slight re-adjustment too.
Is a stack of stacks the same as doing a longer stack?
My rusty school maths says it should be - but thought I'd see if anyone else does this.
(I guess the setting wouldn't be there otherwise)
Hi is anyone using Regim to stack using a dslr modded , currently trying to work out the settings in regim , im using a modified canon 1000D , do i need to set up libraw within regim ? if anyone has good success in using regim i would be interested in hearing what settings you are using .

This is probably silly, but anyway here it goes....
What would happen if say someone intended to shoot 100 of 60sec subs of orion nebula or Andromeda, and clouds rolled in the middle of the session or just got bored and stopped for a hot beverage.
Now this poor fellow is left with only 50 subs and starts thinking of copying and renaming these 50 subs in the same folder (unaltered or with slight denoise or slight Gaussian blur) and stacking all of the 100 subs?
