Hi Cloudy Nights!
I was hoping I could get an opinion on upgrading my imaging rig.
I have recently purchased a HEQ5 Pro with Rowan belt modifications. I am learning pH2 autoguiding and have got a choice of a 60mm F3.75 guidescope and a 30mm F4 Svbony guidescope.
I have an ASI120mm-S, ASI 174mm, Canon dSLR (astro modded) 100D, Canon 6D (stock) cameras.
I am thinking of upgrading also to a mono imaging with RGB and also Narrowband filters (I think 2 inch filter size)...
I have got a 70mm ED refractor F6 (Altair Astro) which I use for solar H-alpha/white light and wide field imaging. I have a 150 mm Newtonian reflector which I have not started to image with yet.
I have a 90mm F10 achromat refractor (upgraded to a GSO dual speed focuser) for mainly solar and planetary imaging. I have found unsatisfactory results from imaging Jupiter on a first attempt but I did not have a good colour camera (only an adapted Logitech webcam). I think this is because the telescope is an achromat.
1) I was thinking if I can get decent results with the 90mm F10 achromat for imaging galaxies and nebulae, and Messier objects, NGC galaxies etc.?
Or 2) will I need a bigger ED or apochromatic refractor ? such as 102 mm or 120mm refractor. I have a 150 mm Newtonian reflector which I am preparing to use for imaging...
Many thanks for your help.
