Astrophotographer 10

I don't know as the kit hasn't arrived yet. They mailed it over a month ago and it must be delayed due to the virus. Yes the 16200 is a good match for the scope. I do find that but I also find the ...

A beautiful image. Love the red Ha areas you picked up. Greg.

Anyone tried Luminar 4? They promoted very heavily about a 1 click sky replacement feature using AI. Greg.

The Samyang 12mm F2 does have considerable blue fringing wide open though so it really needs to be stopped down. Greg.

Yes I realise the limitations when imaging untracked and 13 seconds makes a lot of sense. It just a nasty limitation. There are lots of trackers on the market these days and not very expensive ...

Good one Jared. Greg.

Oh right, I thought I had seen you post about the AP Honders before. I found out recently that AP has an update kit for the RHA to reduce halos and reflections. Something later versions had. Mine ...

Premium Japanese ED glass is FPL53. If they don't state that's what it is then it will be a lesser grade ED glass (still good). ED doublet would not be that great for imaging and is likely to ...

I have used a Vixen Polarie for years and its easy to use, very reliable and easy to polar align, well fairly easy. I also have a Fornax Lightrack 11 and its also a nice unit but has to be reset ...

I 2nd what Jared said. I have a Redcat 51 and its a cool little scope/lens. With some tilt adjustment it can handle a full frame camera which is impressive and its very sharp. Handy for ...

I see lots of excellent images these days from people using something like a Stellarvue SV70 or 80. https://www.stellarvue.com/telescopes/ Stellarvue has flatteners, reducers for their scopes as ...

A solid image Jared. I have a similar setup. I use a FLI ML16200 which is a good camera for sure and 6 electron read noise at the slower digitisation rate. Is this the Officina Stellare 12 inch ...

Don't expect too much from 13 seconds total exposure time. I would increase that considerably to get deep enough to be able to capture deep colour. These modern Sony based cameras have low read ...

I get the green quite often and one time in particular I was amazed at how bright it was. The orangy colours though I tend to only get slight trails. Is this at altitude? I know you have lots of ...

Yes but there is a magnification factor by using a smaller sensor. Its the same as the magnification you get from cropping. Greg.

On buying these lenses off Ebay. I prefer a Japanese seller, usually a shop, as they have very high standards and seem to be very honest. The lenses I have bought that way were all in better ...

I don't think the fact they were designed for 60mm x 70mm film means the crop factor is larger than normal, its your sensor size but I may have that wrong. I have the 645 300mm F4 EDIF lens and it ...

I have used lots of Pentax old lenses. The best one is a 300mm F4DIF with 2 ED glass elements. I used it quite a bit: https://pbase.com/gregbradley/image/170433412/large There are several images ...

I have used a number of different types of lenses for astro. There are some excellent lens 2nd hand that have ED glass in them. Pentax 645 F4 EDIF is a lens I used a lot in the last year. It has 2 ...

Autofocus usually does not work on stars. It probably would on the moon. But you really want to do manual focusing. Set ISO to 6400, open up the lens aperture. Point camera at a bright area of ...
