I have been imaging in monochrome for quite some time except with a DSLR for Neowise.
I see there is new offerings of cooled OSC out. I'd like to maybe buy one that would get closer to my DSLR sensor size.
What are the good ones out there that offers the best price/quality ratio without having to remortgage the house? ๐Ÿ˜‰ and what filter would be needed to offset Bortle 5 light pollution? I see prolong has a few filters available.

Thank you

I guess ASI2600MC Pro or QHY268C would be good choices. Both about $2000.

Then there's older ASI071MC Pro about $1700.

 

If you have mono then why do you think you need colour ?

DX or APS-C image sensor format being approximately 24x16 mm (Nikon). FX-format sensor measures 36x24mm (Nikon).

 

I have a ZWO ASI294MC-Pro which is cooled and has a 4/3" Sony IMX294 CMOS sensor and 4.63ยต pixels. The price is fair at $1,000. There are newer cameras out there with FX sized sensor such as the ZWO ASI6200MC-Pro with 3.76ยตm pixels at $4,000.

 

I am currently using a dated Orion Sky Glow filter in a Starizona Filter drawer but will be saving my money for a mult0band filter (~$400).

 

There are a lot of choices out there from ZWO and QHY. Have fun, and if you like, the members here will gladly spend your money.

I use the 2600mc pro with a triad ultra but it also worked great with the l-enhance filter and for full spectrum i use the l-pro when needed otherwise i just remove gradients in PI

ASI 2600MC Pro is a great cooled color cam and it is 26MP, APS-C sized.

 

I am also Bortle 5 and I use an Optolong L-Pro for broadband targets and an Optolong L-eXtreme for narrowband.

Isn't it the ASI294MC-Pro that has really bad amp glow?
Hahaha I know I can get lots of money blown away in this hobby just by reading this forum. ๐Ÿ˜ณ๐Ÿ˜

How do you use those filters? With a drawer or they are screwed on in the sampling train?

I had a 294MC pro before moving to the 1600MM ... fabulous camera, amp glow calibrates out without issue. I used the Optlong L Pro filter in SQM 19.5 skies . Below is a stack of only 10 90 sec subs with minimal processing ...

Moving to a filter drawer but my FF/FR can have 2" filters screwed on in the front.

I've not had good luck with any lp filters for the 2600 and my Bortle 5 skies.  I bought the celestrin lp filter and it works to a point.  I still get gradients in the east and west.  To the North is horrible....Indianapolis is 6 miles north and I get magenta and green gradients if I shoot in that direction.  I'd love to know if there was a filter that would help with that severe a light gradient.

I have absolutely no issues with amp glow from my 294MC Pro

 

I use the Altair Tri Band filter and find it does an excellent job from my crappy home skies.

 

I was using the 5 position 2" EFW populated with the Tri-band, IR/UV, Oiii and Hb filters but found that I really just image with the Tri band now so I switched to the ASI filter drawer for just the Tri Band and IR/UV filters and moved the Hb and Oiii filters back to my manual wheel I use with my 11 Edge for visual use.

I use this awesome drawer. It is a drop in replacement for the ZWO 21mm spacer.

What do you use the IR/UV filter for? I am waiting on delivery of my 294MC Pro and was under the impression that they are not really necessary for DSO imaging, just planetary.
